# CrossDesk Privacy Policy
|
||||
|
||||
Last updated: August 8, 2026
|
||||
|
||||
[中文](#中文) | [English](#english)
|
||||
|
||||
## 中文
|
||||
|
||||
### 适用范围
|
||||
|
||||
本隐私政策适用于 CrossDesk 桌面客户端及项目提供的默认网络服务。用户自行部署或指定的服务器由相应服务器运营者负责，其数据处理方式不在本政策控制范围内。
|
||||
|
||||
### 网络通信
|
||||
|
||||
CrossDesk 是远程桌面软件，需要通过网络完成设备发现、连接协商及远程会话。客户端可能进行以下网络通信：
|
||||
|
||||
- **默认服务：** 未启用自托管时，客户端会连接预配置的 CrossDesk 服务（`api.crossdesk.cn`），用于设备注册、信令、网络地址转换（NAT）穿透，并在无法建立直接连接时提供中继。
|
||||
- **版本检查：** 客户端启动时会从 CrossDesk 版本服务（`version.crossdesk.cn`）获取最新版本信息。当前即使启用自托管，版本检查仍会访问 CrossDesk 版本服务。
|
||||
- **远程会话：** 用户主动发起或接受远程连接后，CrossDesk 会根据使用的功能在设备之间传输屏幕画面、音频、键盘和鼠标输入、剪贴板文本以及用户选择传输的文件。剪贴板文本可能在远程会话期间自动同步。这些数据可能通过直接连接传输，也可能在必要时通过配置的中继服务器转发。
|
||||
- **自托管：** 用户可以在设置中指定自己的信令及中继服务器。自托管服务器的日志、数据保存和访问规则由其运营者决定。
|
||||
|
||||
### 处理的信息
|
||||
|
||||
为提供上述功能，CrossDesk 可能处理：
|
||||
|
||||
- 连接所需的设备标识及认证信息；
|
||||
- IP 地址、端口、连接时间、连接状态等必要的网络元数据；
|
||||
- 版本检查请求产生的标准网络请求信息；
|
||||
- 用户授权的远程会话中处理的屏幕、音频、控制指令、剪贴板及文件内容。
|
||||
|
||||
### 信息的使用与保存
|
||||
|
||||
- 设备标识、连接设置及用户偏好会保存在本地设备上，以便后续使用。
|
||||
- 通过官方信令和中继服务处理的信息仅用于建立、维持和转发 CrossDesk 连接，以及服务运行、安全防护和故障排查。
|
||||
- 中继传输的远程会话内容仅用于实时转发，不用于广告或用户画像。
|
||||
- CrossDesk 桌面客户端不包含广告功能，也不会主动上传诊断日志、崩溃报告或用户行为分析数据。
|
||||
- 自托管服务器可能保存的日志和数据由其运营者控制，请向相应运营者了解其隐私与保存政策。
|
||||
|
||||
### 用户选择
|
||||
|
||||
用户可以：
|
||||
|
||||
- 配置自托管服务器，以替代默认信令和中继服务；
|
||||
- 决定是否发起或接受远程会话；
|
||||
- 决定是否选择并传输文件；
|
||||
- 结束远程会话，以停止会话数据传输；
|
||||
- 删除 CrossDesk 的本地配置、缓存及日志文件。
|
||||
|
||||
### 政策更新与联系方式
|
||||
|
||||
本政策可能随着 CrossDesk 功能或网络服务的变化而更新。更新内容将在本文件中发布。如有隐私相关问题，请联系 [junkun.di@hotmail.com](mailto:junkun.di@hotmail.com)。
|
||||
|
||||

|
||||
|
||||
## English
|
||||
|
||||
### Scope
|
||||
|
||||
This Privacy Policy applies to the CrossDesk desktop client and the default network services provided by the project. Servers deployed or selected by users are operated by their respective administrators, and their data-processing practices are outside the control of this policy.
|
||||
|
||||
### Network communications
|
||||
|
||||
CrossDesk is remote desktop software and requires network communications for device discovery, connection negotiation, and remote sessions. The client may perform the following communications:
|
||||
|
||||
- **Default services:** Unless self-hosting is enabled, the client connects to preconfigured CrossDesk services (`api.crossdesk.cn`) for device registration, signaling, network address translation (NAT) traversal, and relay when a direct connection cannot be established.
|
||||
- **Update checks:** On startup, the client retrieves current release information from the CrossDesk version service (`version.crossdesk.cn`). Update checks currently continue to use the CrossDesk version service even when self-hosting is enabled.
|
||||
- **Remote sessions:** After a user initiates or accepts a remote connection, CrossDesk transmits the data required by enabled features between devices. This may include screen content, audio, keyboard and mouse input, clipboard text, and files selected by the user. Clipboard text may be synchronized automatically during a remote session. Data may travel over a direct connection or through the configured relay server when necessary.
|
||||
- **Self-hosting:** Users may configure their own signaling and relay servers. Logging, retention, and access policies for a self-hosted server are determined by its operator.
|
||||
|
||||
### Information processed
|
||||
|
||||
To provide these functions, CrossDesk may process:
|
||||
|
||||
- device identifiers and authentication information required for connections;
|
||||
- necessary network metadata, such as IP addresses, ports, connection times, and connection status;
|
||||
- standard network request information generated by update checks; and
|
||||
- screen, audio, control, clipboard, and file content processed during a remote session authorized by the user.
|
||||
|
||||
### Use and storage of information
|
||||
|
||||
- Device identifiers, connection settings, and user preferences are stored locally for subsequent use.
|
||||
- Information processed by the official signaling and relay services is used only to establish, maintain, and relay CrossDesk connections and for service operation, security, and troubleshooting.
|
||||
- Remote-session content passing through a relay is used only for real-time forwarding and is not used for advertising or user profiling.
|
||||
- The CrossDesk desktop client does not contain advertising functionality and does not intentionally upload diagnostic logs, crash reports, or behavioral analytics.
|
||||
- Logs and data that may be retained by self-hosted servers are controlled by their operators. Contact the relevant operator for its privacy and retention practices.
|
||||
|
||||
### User choices
|
||||
|
||||
Users may:
|
||||
|
||||
- configure a self-hosted server instead of the default signaling and relay services;
|
||||
- choose whether to initiate or accept a remote session;
|
||||
- choose whether to select and transfer files;
|
||||
- end a remote session to stop session-data transmission; and
|
||||
- remove local CrossDesk configuration, cache, and log files.
|
||||
|
||||
### Changes and contact
|
||||
|
||||
This policy may be updated as CrossDesk features or network services change. Updates will be published in this file. For privacy-related questions, contact [junkun.di@hotmail.com](mailto:junkun.di@hotmail.com).

## 简介
|
||||
|
||||
CrossDesk 是一个轻量级的跨平台远程桌面软件，支持 Web 端控制远程设备。
|
||||
|
||||
CrossDesk 是 [MiniRTC](https://github.com/kunkundi/minirtc.git) 实时音视频传输库的实验性应用。MiniRTC 是一个轻量级的跨平台实时音视频传输库。它具有网络透传（[RFC5245](https://datatracker.ietf.org/doc/html/rfc5245)），视频软硬编解码（H264/AV1），音频编解码（[Opus](https://github.com/xiph/opus)），信令交互，网络拥塞控制，传输加密（[SRTP](https://tools.ietf.org/html/rfc3711)）等基础能力。
|
||||
|
||||
## 系统要求
|
||||
|
||||
| 平台 | 最低版本 |
|
||||
|----------------|---------------------------|
|
||||
| **Windows** | Windows 10 及以上 (64 位) |
|
||||
| **macOS** | macOS Intel 15.0 及以上 ( 大于 14.0 小于 15.0 的版本可自行编译实现兼容 )<br> macOS Apple Silicon 14.0 及以上 |
|
||||
| **Linux** | Ubuntu 20.04 及以上 |
|
||||
|
||||
## 使用
|
||||
|
||||
在菜单栏“对端ID”处输入远端桌面的ID，点击“→”即可发起远程连接。
|
||||
|
||||
|
||||
|
||||
如果远端桌面设置了连接密码，则本端需填写正确的连接密码才能成功发起远程连接。
|
||||
|
||||
|
||||
|
||||
发起连接前，可在设置中自定义配置项，如语言、视频编码格式等。
|
||||
|
||||
|
||||
### Web 客户端
|
||||
浏览器访问 [CrossDesk Web Client](https://web.crossdesk.cn/)。
|
||||
输入 **远程设备 ID** 与 **密码**，点击连接即可接入远程设备。如图，**iOS Safari 远程控制 Win11**：
|
||||
|
||||
在浏览器中输入远程设备 ID 和密码，无需在控制端安装桌面客户端。

|
||||
</p>
|
||||
### Windows 服务（CrossDesk Service）
|
||||
CrossDesk 在 Windows 平台提供本地辅助服务 **CrossDesk Service**，服务名为 `CrossDeskService`。该服务用于锁屏、登录界面和安全桌面等受保护场景下的远程控制增强能力，包括：
|
||||
- 上报远端当前是否处于锁屏、登录、凭据输入或安全桌面状态；
|
||||
- 支持从控制端发送 `Ctrl+Alt+Del`（SAS）；
|
||||
- 在锁屏、登录和安全桌面阶段转发键盘、鼠标输入。
|
||||
|
||||
图片来源与更新方式见 [截图说明](docs/images/README.md)。
|
||||
Windows 安装包会自动打包 `crossdesk_service.exe` 和 `crossdesk_session_helper.exe`，并在安装时注册为按需启动的 Windows 服务。CrossDesk 客户端启动时会尝试启动已安装的服务；当本机没有 CrossDesk 客户端进程运行时，服务会自动退出。卸载客户端时会同步停止并移除该服务。
|
||||
|
||||

|
||||
|
||||
## 下载与安装
|
||||
|
||||
前往 [GitHub Releases](https://github.com/kunkundi/crossdesk/releases) 或 [官方网站](https://www.crossdesk.cn/)，按系统与 CPU 架构选择安装包。
|
||||
|
||||
| 平台 | 当前源码 / CI 基线 | 安装方式 |
|
||||
| --- | --- | --- |
|
||||
| Windows | Windows 10+，x64 | `.exe` 安装包；便携构建也受支持 |
|
||||
| macOS | macOS 14.0+，Intel / Apple Silicon | 选择 x64 或 arm64 的 `.pkg` |
|
||||
| Linux | Ubuntu 20.04+，amd64 / arm64，glibc 2.31 基线 | `.deb` 安装包 |
|
||||
| iOS / iPadOS | iOS 16.0+，arm64 真机 | 原生客户端；使用 Xcode 构建并签名，CI 产物为未签名应用 |
|
||||
| Web | 支持 WebRTC 的浏览器 | 访问 [web.crossdesk.cn](https://web.crossdesk.cn/) |
|
||||
|
||||
Linux 下载后，在下载目录中将文件名替换为实际安装包名称：
|
||||
|
||||
```bash
|
||||
sudo apt install "./crossdesk-linux-amd64-<version>.deb"
|
||||
如果是手动编译或手动部署 Windows 版本，请确保 `CrossDesk.exe`、`crossdesk_service.exe` 和 `crossdesk_session_helper.exe` 位于同一目录。安装或卸载服务需要使用管理员权限打开 PowerShell：
|
||||
```
|
||||
|
||||
**macOS 首次运行：** 按应用提示，在“系统设置 → 隐私与安全性”中授予 CrossDesk **屏幕录制**（新系统可能显示为“屏幕与系统音频录制”）及 **辅助功能**权限，再按系统提示重新打开应用。前者用于捕获桌面，后者用于远程键鼠输入。
|
||||
|
||||
<a id="quick-start"></a>
|
||||
|
||||
## 快速连接
|
||||
|
||||
### 从另一台电脑连接
|
||||
|
||||
1. **准备被控电脑。** 安装并运行 CrossDesk，等待底部显示“已连接服务器”。在左侧“本桌面”查看 **本机 ID** 和 **密码**，提供给控制端。
|
||||
2. **输入对端 ID。** 在控制端右侧“远程桌面 → 对端 ID”输入被控电脑的 ID，点击 **→**。
|
||||
3. **完成密码验证。** 按弹窗输入被控电脑当前的连接密码，确认后等待远程画面出现。需要保存密码时勾选“记住密码”。
|
||||
4. **再次连接。** 成功连接过的设备会出现在“近期连接”中，可通过卡片重连，也可编辑别名或删除记录。
|
||||
|
||||
本机密码旁的眼睛按钮用于显示 / 隐藏密码，刷新按钮用于生成新的随机密码，铅笔按钮用于手动修改。密码统一为 **6 位数字或英文字母**。修改或刷新时需保持连接服务器；等待修改成功、客户端重新连接后，再复制当前密码。已保存旧密码的控制端需重新输入。
|
||||
|
||||
### 从浏览器连接
|
||||
|
||||
1. 保持被控电脑上的 CrossDesk 运行，并确认已连接服务器。
|
||||
2. 打开 [Web 客户端](https://web.crossdesk.cn/)，输入 **远程设备 ID** 和 **密码**，点击“连接”。
|
||||
3. 连接后使用页面提供的显示器、鼠标模式和键盘控件操作远端；手机和平板也可通过浏览器访问。
|
||||
|
||||
如果使用自建服务器，需要让控制端与被控端接入同一服务；Web 部署配置见 [CrossDesk Web Client](https://github.com/kunkundi/crossdesk-web-client)。
|
||||
|
||||
<a id="session"></a>
|
||||
|
||||
## 会话中的常用操作
|
||||
|
||||
远程窗口通过会话标签切换设备，控制栏提供以下操作；控制栏收起时先点击展开按钮。将鼠标悬停在图标上可查看提示。
|
||||
|
||||
| 入口 | 用途 |
|
||||
| --- | --- |
|
||||
| 显示器 | 切换远端显示器 |
|
||||
| 键盘 | 发送组合键；Windows 的 `Ctrl+Alt+Del` 依赖远端服务 |
|
||||
| 鼠标 | 控制 / 释放远端鼠标 |
|
||||
| 扬声器 | 播放声音 / 静音 |
|
||||
| 文件夹 | 选择文件发送到远端，并查看传输进度 |
|

|
||||
| 全屏 | 进入 / 退出全屏 |
|
||||
| 断开连接 | 结束当前远程会话 |
|
||||
|
||||
桌面端可同步文本剪贴板。接收文件的位置可在“设置 → 文件保存路径”调整。关闭主窗口会隐藏窗口并保持程序运行；需要完全退出时使用系统托盘或菜单栏中的退出入口。
|
||||
|
||||
### 在会话中调整画面
|
||||
|
||||
连接成功后，点击工具栏中的 **画面设置**（滑杆图标），直接选择低 / 中 / 高画质、**30 / 60 fps**，以及帧率优先 / 画质优先 / 平衡。选项会发送给当前被控端，无需断开重连；实际画面效果取决于网络、设备与编码器能力。旧版被控端不支持时，菜单会提示并禁用选项。

|
||||
|
||||
## 原生 iOS / iPadOS 客户端
|
||||
|
||||
仓库的 [`apps/ios`](apps/ios/README.md) 提供原生控制端，与桌面端使用同一套 MiniRTC 协议。它可以控制远端电脑；当前不提供将 iPhone / iPad 作为被控桌面的功能。
|
||||
|
||||
1. 按 [iOS 开发说明](apps/ios/README.md) 使用 Xcode 构建并签名，安装到 iOS 16+ 的真机。
|
||||
2. 在首页输入对端 ID，点击连接并填写密码；成功连接后可从“最近连接”中重连。
|
||||
3. 在设置中选择鼠标模式：**相对位置**像触控板一样移动光标，**绝对位置**将触摸位置直接映射到远端画面。
|
||||
4. 点击悬浮图标展开菜单，可切换显示器、显示键盘、控制声音或发送文件。收到的文件位于应用的 `Documents/Received`，可通过传输状态旁的分享按钮导出。
|
||||
|
||||
当前支持接收远端文本到 iOS 剪贴板；界面暂未提供主动发送本机剪贴板的按钮。
|
||||
|
||||
当前支持单指点击、双指右键、长按拖动与捏合缩放；缩放后的双指平移用于移动视图。原生端与浏览器端分别维护，使用入口和手势可能不同。
|
||||
|
||||
<a id="windows-service"></a>
|
||||
|
||||
## Windows 锁屏与登录界面
|
||||
|
||||
**CrossDesk Service**（服务名 `CrossDeskService`）提供锁屏、登录、凭据输入及安全桌面的状态上报、`Ctrl+Alt+Del` 发送和键鼠输入转发。
|
||||
|
||||
安装版会注册按需启动的服务，客户端启动时尝试启动它；本机没有 CrossDesk 客户端进程后服务会自动退出。便携版可在提示窗口或“设置 → 锁屏控制服务”中安装服务，需要管理员权限。该服务依赖客户端运行。
|
||||
|
||||
<details>
|
||||
<summary>手动部署与服务管理命令</summary>
|
||||
|
||||
保留完整安装目录；自行部署构建产物时，将 `CrossDesk.exe`、`crossdesk_service.exe`、`crossdesk_session_helper.exe` 及同次构建输出的全部 `.dll` 放在同一目录。在该目录打开管理员 PowerShell，按需执行：
|
||||
|
||||
```powershell
|
||||
# 安装
|
||||
.\CrossDesk.exe --service-install
|
||||
# 启动
|
||||
.\CrossDesk.exe --service-start
|
||||
# 查看状态
|
||||
.\CrossDesk.exe --service-status
|
||||
.\CrossDesk.exe --service-ping
|
||||
# 停止或卸载服务
|
||||
.\CrossDesk.exe --service-stop
|
||||
# 卸载
|
||||
.\CrossDesk.exe --service-uninstall
|
||||
```
|
||||
|
||||
</details>
|
||||
如果远端 Windows 服务未安装、未启动或暂时不可用，基础远程桌面连接仍可使用，但锁屏、登录界面和安全桌面阶段的控制能力会受限，客户端会提示“远端Windows服务不可用”。
|
||||
|
||||
出现“远端 Windows 服务不可用”时，检查被控电脑的安装和服务状态；普通桌面连接仍可使用，受保护界面的控制能力会受限。
|
||||
## 如何编译
|
||||
|
||||
<a id="self-hosting"></a>
|
||||
依赖：
|
||||
- [xmake](https://xmake.io/#/guide/installation)
|
||||
- [cmake](https://cmake.org/download/) 3.21 及以上
|
||||
|
||||
### Linux
|
||||
|
||||
Linux 构建支持 Ubuntu 20.04 及以上版本的 amd64 和 arm64。发布安装包以
|
||||
Ubuntu 20.04/glibc 2.31 为兼容基线。先安装基础编译依赖：
|
||||
|
||||
```bash
|
||||
sudo apt-get update
|
||||
sudo apt-get install -y \
|
||||
git curl unzip build-essential gcc-10 g++-10 python3-pip \
|
||||
pkg-config binutils dpkg-dev \
|
||||
libx11-dev libxext-dev libxrender-dev libxft-dev libxrandr-dev \
|
||||
libxinerama-dev libxcursor-dev libxi-dev libxfixes-dev libxv-dev \
|
||||
libxtst-dev libxcb-randr0-dev libxcb-xtest0-dev libxcb-xinerama0-dev \
|
||||
libxcb-shape0-dev libxcb-xkb-dev libxcb-xfixes0-dev libxcb-shm0-dev \
|
||||
libasound2-dev libsndio-dev libpulse-dev
|
||||
|
||||
# Ubuntu 20.04 自带的 CMake 3.16 不满足 Slint 1.17 的要求
|
||||
python3 -m pip install --user cmake==3.31.6
|
||||
export PATH="$HOME/.local/bin:$PATH"
|
||||
```
|
||||
|
||||
Ubuntu 20.04 默认的 GCC 9 缺少 Slint C++ API 所需的部分 C++20 标准库，
|
||||
因此上述命令同时安装并在后续配置中指定 GCC 10。
|
||||
|
||||
需要启用 Wayland 捕获或 DRM 捕获时，再安装对应依赖：
|
||||
|
||||
```bash
|
||||
sudo apt-get install -y libdbus-1-dev libdrm-dev
|
||||
|
||||
# Ubuntu 22.04 及以上也可以直接安装系统开发包
|
||||
# sudo apt-get install -y libpipewire-0.3-dev libspa-0.2-dev
|
||||
```
|
||||
|
||||
下载子模块并编译 Release 版本：
|
||||
|
||||
```bash
|
||||
git clone --recurse-submodules https://github.com/kunkundi/crossdesk.git
|
||||
cd crossdesk
|
||||
|
||||
# 已经克隆过仓库时执行这一行
|
||||
git submodule update --init --recursive
|
||||
|
||||
# Ubuntu 20.04 没有 PipeWire 0.3 开发包，安装仅用于编译的头文件 SDK。
|
||||
# 已安装发行版 PipeWire 0.3 开发包时可跳过此步骤。
|
||||
sudo ./docker/linux-build/install-pipewire-sdk.sh
|
||||
|
||||
xmake f -m release --USE_CUDA=false --cc=gcc-10 --cxx=g++-10 -y
|
||||
xmake b -vy crossdesk
|
||||
```
|
||||
|
||||
amd64 构建结果位于 `build/linux/x86_64/release/crossdesk`，arm64 构建结果位于 `build/linux/arm64/release/crossdesk`。
|
||||
|
||||
启用 Wayland 和 DRM 的配置示例：
|
||||
|
||||
```bash
|
||||
xmake f -m release --USE_WAYLAND=true --USE_DRM=true --USE_CUDA=false \
|
||||
--cc=gcc-10 --cxx=g++-10 -y
|
||||
xmake b -vy crossdesk
|
||||
```
|
||||
|
||||
生成 Debian 安装包（必须在对应架构上先完成 Release 编译）：
|
||||
|
||||
```bash
|
||||
# amd64
|
||||
./scripts/linux/pkg_amd64.sh 1.0.0
|
||||
|
||||
# arm64
|
||||
./scripts/linux/pkg_arm64.sh 1.0.0
|
||||
```
|
||||
|
||||
打包脚本会将 Slint 共享运行库安装到软件包私有目录 `/usr/lib/crossdesk`，无需用户另外安装 `libslint_cpp.so`。
|
||||
PipeWire 不属于强制运行时依赖：程序在运行时检测宿主系统的 PipeWire 0.3，
|
||||
没有该运行库时仍可使用 X11（以及构建时启用的 DRM）捕获。
|
||||
|
||||
### 通用编译选项
|
||||
|
||||
```text
|
||||
--USE_CUDA=true/false: 启用 CUDA 硬件编解码，默认不启用
|
||||
--USE_WAYLAND=true/false: 在 Linux 上启用 Wayland/PipeWire 捕获，默认不启用
|
||||
--USE_DRM=true/false: 在 Linux 上启用 DRM 捕获，默认不启用
|
||||
--CROSSDESK_PORTABLE=true/false: 构建便携版本，默认不启用
|
||||
--CROSSDESK_VERSION=xxx: 指定 CrossDesk 的版本
|
||||
|
||||
# 示例
|
||||
xmake f --CROSSDESK_VERSION=1.0.0 --USE_CUDA=true
|
||||
```
|
||||
|
||||
运行：
|
||||
|
||||
```bash
|
||||
xmake r crossdesk
|
||||
```
|
||||
|
||||
### 无 CUDA 环境下的开发支持
|
||||
|
||||
对于**未安装 CUDA 环境的 Linux 开发者，如果希望编译后的成果物拥有硬件编解码能力**，这里提供了预配置的 [Ubuntu 20.04 兼容构建镜像](https://hub.docker.com/r/crossdesk/ubuntu20.04)。该镜像内置必要的构建依赖，可生成兼容 glibc 2.31 的单一 Linux 安装包。
|
||||
|
||||
进入容器，下载工程后执行：
|
||||
```
|
||||
export CUDA_PATH=/usr/local/cuda
|
||||
export XMAKE_GLOBALDIR=/data
|
||||
|
||||
xmake f --USE_CUDA=true
|
||||
xmake b --root -vy crossdesk
|
||||
```
|
||||
|
||||
对于**未安装 CUDA 环境的 Windows 开发者**，执行下面的命令安装 CUDA 编译环境：
|
||||
```
|
||||
xmake require -vy "cuda 12.6.3"
|
||||
```
|
||||
安装完成后执行:
|
||||
```
|
||||
xmake require --info "cuda 12.6.3"
|
||||
```
|
||||
输出如下:
|
||||
|
||||
<img width="860" height="226" alt="Image" src="https://github.com/user-attachments/assets/999ac365-581a-4b9a-806e-05eb3e4cf44d" />
|
||||
|
||||
根据上述输出获取到 CUDA 的安装目录，即 installdir 指向的位置。将 CUDA_PATH 加入系统环境变量，或在终端中输入：
|
||||
```
|
||||
set CUDA_PATH=path_to_cuda_installdir
|
||||
```
|
||||
重新执行：
|
||||
```
|
||||
xmake f --USE_CUDA=true
|
||||
xmake b -vy crossdesk
|
||||
```
|
||||
|
||||
#### 注意
|
||||
运行时如果客户端状态栏显示 **未连接服务器**，请先在 [CrossDesk 官方网站](https://www.crossdesk.cn/) 安装客户端，以便在环境中安装所需的证书文件。
|
||||
|
||||
<img width="256" height="120" alt="image" src="https://github.com/user-attachments/assets/1812f7d6-516b-4b4f-8a3d-98bee505cc5a" />

## 自托管服务器
|
||||
推荐使用Docker部署CrossDesk Server。
|
||||
```bash
|
||||
sudo docker run -d \
|
||||
--name crossdesk_server \
|
||||
--network host \
|
||||
-e EXTERNAL_IP=xxx.xxx.xxx.xxx \
|
||||
-e INTERNAL_IP=xxx.xxx.xxx.xxx \
|
||||
-e CROSSDESK_SERVER_PORT=xxxx \
|
||||
-e COTURN_PORT=xxxx \
|
||||
-e MIN_PORT=xxxxx \
|
||||
-e MAX_PORT=xxxxx \
|
||||
-v /var/lib/crossdesk:/var/lib/crossdesk \
|
||||
-v /var/log/crossdesk:/var/log/crossdesk \
|
||||
crossdesk/crossdesk-server:v1.1.6
|
||||
```
|
||||
|
||||
可自行部署信令服务与 TURN 中继，并在桌面客户端 **☰ → 设置 → 自托管配置** 中填写连接信息。控制端与被控端都需要启用同一套配置。
|
||||
上述命令中，用户需注意的参数如下：
|
||||
|
||||
- [自托管指南](docs/SELF_HOSTING.md)：当前 Compose 部署入口、客户端设置、证书信任与排查。
|
||||
- [CrossDesk Server](https://github.com/kunkundi/crossdesk-server)：服务端源码与发布配置。
|
||||
- [CrossDesk Web Client](https://github.com/kunkundi/crossdesk-web-client)：浏览器端源码与自托管说明。
|
||||
**参数**
|
||||
- EXTERNAL_IP：服务器公网 IP , 对应 CrossDesk 客户端**自托管服务器配置**中填写的**服务器地址**
|
||||
- INTERNAL_IP：服务器内网 IP
|
||||
- CROSSDESK_SERVER_PORT：自托管服务使用的端口，对应 CrossDesk 客户端**自托管服务器配置**中填写的**服务器端口**
|
||||
- COTURN_PORT: COTURN 服务使用的端口, 对应 CrossDesk 客户端**自托管服务器配置**中填写的**中继服务端口**
|
||||
- MIN_PORT/MAX_PORT：COTURN 服务使用的端口范围，例如：MIN_PORT=50000, MAX_PORT=60000，范围可根据客户端数量调整。
|
||||
- `-v /var/lib/crossdesk:/var/lib/crossdesk`：持久化数据库和证书文件到宿主机
|
||||
- `-v /var/log/crossdesk:/var/log/crossdesk`：持久化日志文件到宿主机
|
||||
|
||||
## 开发与反馈
|
||||
**示例**：
|
||||
```bash
|
||||
sudo docker run -d \
|
||||
--name crossdesk_server \
|
||||
--network host \
|
||||
-e EXTERNAL_IP=114.114.114.114 \
|
||||
-e INTERNAL_IP=10.0.0.1 \
|
||||
-e CROSSDESK_SERVER_PORT=9099 \
|
||||
-e COTURN_PORT=3478 \
|
||||
-e MIN_PORT=50000 \
|
||||
-e MAX_PORT=60000 \
|
||||
-v /var/lib/crossdesk:/var/lib/crossdesk \
|
||||
-v /var/log/crossdesk:/var/log/crossdesk \
|
||||
crossdesk/crossdesk-server:v1.1.6

**注意**：
|
||||
- **服务器需开放端口：COTURN_PORT/udp，COTURN_PORT/tcp，MIN_PORT-MAX_PORT/udp，CROSSDESK_SERVER_PORT/tcp。**
|
||||
- 如果不挂载 volume，容器删除后数据会丢失
|
||||
- 证书文件会在首次启动时自动生成并持久化到宿主机的 `/var/lib/crossdesk/certs` 路径下。由于默认使用的是自签证书，无法保障安全性，建议在云服务商申请正式证书放到该目录下并重启服务。
|
||||
- 数据库文件会自动创建并持久化到宿主机的 `/var/lib/crossdesk/db/crossdesk-server.db` 路径下
|
||||
- 日志文件会自动创建并持久化到宿主机的 `/var/log/crossdesk/` 路径下
|
||||
|
||||
## 致谢与许可
|
||||
**权限注意**：如果 Docker 自动创建的目录权限不足（属于 root），容器内用户无法写入，会导致：
|
||||
- 证书生成失败，容器启动脚本会报错退出
|
||||
- 数据库目录创建失败，程序会抛出异常并崩溃
|
||||
- 日志目录创建失败，日志文件无法写入（但程序可能继续运行）
|
||||
|
||||
**解决方案**：在启动容器前手动设置权限：
|
||||
```bash
|
||||
sudo mkdir -p /var/lib/crossdesk /var/log/crossdesk
|
||||
sudo chown -R $(id -u):$(id -g) /var/lib/crossdesk /var/log/crossdesk
|
||||

||||
<img width="645" height="300" alt="_cgi-bin_mmwebwx-bin_webwxgetmsgimg__ MsgID=932911462648581698 skey=@crypt_1f5153b1_b550ca7462b5009ce03c991cca2a92a7 mmweb_appid=wx_webfilehelper" src="https://github.com/user-attachments/assets/a5109e6f-752c-4654-9f4e-7e161bddf43e" />
|
||||
|
||||
### Windows Service (CrossDesk Service)
|
||||
CrossDesk provides a local helper service on Windows named **CrossDesk Service**. Its service name is `CrossDeskService`. The service improves remote control in protected Windows states such as the lock screen, sign-in UI, credential UI, and secure desktop. It provides:
|
||||
- Remote status reporting for lock screen, sign-in, credential, and secure desktop states.
|
||||
- Remote `Ctrl+Alt+Del` (SAS) delivery.
|
||||
- Keyboard and mouse input forwarding while the remote Windows device is on the lock screen, sign-in UI, or secure desktop.
|
||||
|
||||
The Windows installer bundles `crossdesk_service.exe` and `crossdesk_session_helper.exe`, then registers the service as an on-demand Windows service during installation. When the CrossDesk client starts, it tries to start the installed service automatically. When no CrossDesk client process is running on the machine, the service exits automatically. Uninstalling the client also stops and removes the service.
|
||||
|
||||
For manual Windows builds or deployments, make sure `CrossDesk.exe`, `crossdesk_service.exe`, and `crossdesk_session_helper.exe` are placed in the same directory. Open PowerShell with administrator privileges to install or uninstall the service:
|
||||
```
|
||||
|
||||
**First launch on macOS:** follow the app prompts to grant **Screen Recording** (called **Screen & System Audio Recording** on newer systems) and **Accessibility** under **System Settings → Privacy & Security**. Reopen the app if prompted. These permissions allow desktop capture and remote keyboard/mouse input respectively.
|
||||
|
||||
<a id="quick-start"></a>
|
||||
|
||||
## Quick start
|
||||
|
||||
### Connect from another computer
|
||||
|
||||
1. **Prepare the host.** Install and run CrossDesk on the computer to control. Wait for the bottom status bar to show that the server is connected. Share the **Local ID** and **Password** shown under **Local Desktop** with the controller.
|
||||
2. **Enter the remote ID.** On the controlling computer, enter the host's ID in **Remote Desktop → Remote ID**, then click **→**.
|
||||
3. **Verify the password.** Enter the host's current connection password when prompted and confirm. Select **Remember password** if you want to save it.
|
||||
4. **Reconnect later.** Previously connected devices appear under **Recent Connections**. Reconnect from a card, edit its alias, or remove its record.
|
||||
|
||||
The eye button shows or hides the local password, the refresh button generates a new random password, and the pencil button lets you edit it. Passwords use **6 ASCII letters or digits**. Stay connected to the server when editing or refreshing a password. Wait for the change to succeed and the client to reconnect, then copy the current password. Controllers that saved the old password must enter it again.
|
||||
|
||||
### Connect from a browser
|
||||
|
||||
1. Keep CrossDesk running and connected to the server on the host computer.
|
||||
2. Open the [Web Client](https://web.crossdesk.cn/), enter the **Remote Device ID** and **Password**, and click **Connect**.
|
||||
3. Use the page's display, mouse-mode, and keyboard controls during the session. Phone and tablet browsers can also connect.
|
||||
|
||||
For self-hosting, connect both sides to the same service. Browser deployment is documented in [CrossDesk Web Client](https://github.com/kunkundi/crossdesk-web-client).
|
||||
|
||||
<a id="session"></a>
|
||||
|
||||
## Session controls
|
||||
|
||||
Switch devices using session tabs. Expand the control bar if it is collapsed, and hover over icons to see their tooltips.
|
||||
|
||||
| Control | Action |
|
||||
| --- | --- |
|
||||
| Display | Switch the remote monitor |
|
||||
| Keyboard | Send shortcuts; Windows `Ctrl+Alt+Del` requires the remote service |
|
||||
| Mouse | Enable / release remote mouse control |
|
||||
| Speaker | Play / mute remote audio |
|
||||
| Folder | Select a file to send and view transfer progress |
|
||||
| Video settings | Adjust video quality, capture frame rate, and video preference during the current session |
|
||||
| Network statistics | Inspect traffic, packet loss, frame rate, resolution, direct / relay mode, and encryption status |
|
||||
| Privacy screen | Enable or disable the host's privacy screen; hover to see its status and available actions |
|
||||
| Fullscreen | Enter / exit fullscreen |
|
||||
| Disconnect | End the current remote session |
|
||||
|
||||
Desktop clients synchronize text clipboard contents. Configure the receiving directory under **Settings → File Save Path**. Closing the main window hides it and keeps the app running; use the system tray or menu-bar exit command to quit completely.
|
||||
|
||||
### Adjust video during a session
|
||||
|
||||
After connecting, open **Video settings** (the sliders icon) in the toolbar. Choose low / medium / high quality, **30 / 60 fps**, and frame-rate priority / quality priority / balanced adaptation. Changes are sent to the current host without reconnecting; actual results depend on the network, device, and encoder. For older hosts that do not support live video settings, the menu explains the limitation and disables the options.

||||
## Client settings and updates
|
||||
|
||||
Open **☰ → Settings** in the top-right corner and click **OK** to save. Configure codecs and connections before connecting; some settings are disabled during an active session.

|
||||
| Enable TURN Service | Allow relay-assisted connections; check this setting if P2P fails |
|
||||
| Force Relay | Require relay connections when TURN is enabled; turning TURN off also disables this option |
|
||||
| Privacy screen on connect | Automatically enable privacy when this computer is controlled remotely; the controller can toggle it from the session toolbar |
|
||||
| Self-Hosted Config | Set the server address and signaling port, then enable the checkbox |

|
||||
|
||||
### Check for updates
|
||||
|
||||
The client checks for updates in the background after launch. A new version adds an update indicator to the main window menu. Open **☰ → About** to view the version or click **Check for updates** to check manually. When an update is available, you can view its release notes and open the download page.

<a id="ios"></a>
|
||||
|
||||
## Native iOS / iPadOS client
|
||||
|
||||
[`apps/ios`](apps/ios/README.md) contains a native controller using the same MiniRTC protocol as the desktop client. It controls remote computers; it does not expose an iPhone or iPad as a remotely controlled desktop.
|
||||
|
||||
1. Follow the [iOS guide](apps/ios/README.md) to build and sign the app with Xcode, then install it on an iOS 16+ physical device.
|
||||
2. Enter a remote ID on the home screen, connect, and enter its password. Successful connections become available in the recent devices list.
|
||||
3. Choose a mouse mode in Settings: **Relative Position** works like a trackpad; **Absolute Position** maps touches directly to the remote screen.
|
||||
4. Tap the floating icon to expand the menu, then switch displays, open the keyboard, toggle audio, or send files. Received files are stored in `Documents/Received` and can be exported using the share button beside the transfer status.
|
||||
|
||||
The app currently receives remote text into the iOS clipboard. Its UI does not yet expose a button to send the local clipboard.
|
||||
|
||||
Gestures include one-finger click, two-finger right-click, long-press drag, and pinch-to-zoom. When zoomed in, two-finger panning moves the viewport. The native and browser clients are maintained separately, so their controls and gestures may differ. The current native UI uses Chinese labels.
|
||||
|
||||
<a id="windows-service"></a>
|
||||
|
||||
## Windows lock screens and sign-in
|
||||
|
||||
**CrossDesk Service** (`CrossDeskService`) reports protected desktop states and forwards `Ctrl+Alt+Del`, keyboard, and mouse input on lock screens, sign-in screens, credential prompts, and secure desktops.
|
||||
|
||||
The installer registers an on-demand service. CrossDesk tries to start it on launch, and the service exits when no local CrossDesk client is running. Portable builds offer service installation in the prompt or **Settings → Lock Screen Service**, with administrator privileges. The service depends on a running client.
|
||||
|
||||
<details>
|
||||
<summary>Manual deployment and service commands</summary>
|
||||
|
||||
Keep the complete installation directory. For manual deployment, place `CrossDesk.exe`, `crossdesk_service.exe`, `crossdesk_session_helper.exe`, and all `.dll` files from the same build together. Open an administrator PowerShell in that directory and run the commands you need:
|
||||
|
||||
```powershell
|
||||
# install
|
||||
.\CrossDesk.exe --service-install
|
||||
# start
|
||||
.\CrossDesk.exe --service-start
|
||||
# check status
|
||||
.\CrossDesk.exe --service-status
|
||||
.\CrossDesk.exe --service-ping
|
||||
# Stop or uninstall the service
|
||||
# stop
|
||||
.\CrossDesk.exe --service-stop
|
||||
# uninstall
|
||||
.\CrossDesk.exe --service-uninstall
|
||||
```
|
||||
|
||||
</details>
|
||||
If the remote Windows service is not installed, not running, or temporarily unavailable, the basic remote desktop connection still works, but remote control on the lock screen, sign-in UI, and secure desktop is limited. The client will show “Remote Windows service unavailable”.
|
||||
|
||||
If **Remote Windows service unavailable** appears, check installation and service status on the host. Ordinary desktop connections remain available, while control of protected screens is limited.
|
||||
## How to build
|
||||
|
||||
<a id="self-hosting"></a>
|
||||
Requirements:
|
||||
- [xmake](https://xmake.io/#/guide/installation)
|
||||
- [cmake](https://cmake.org/download/) 3.21 or later
|
||||
|
||||
## Self-hosting
|
||||
### Linux
|
||||
|
||||
Host your own signaling and TURN services, then enter their connection details under **☰ → Settings → Self-Hosted Config**. Enable the same server configuration on both the controller and host.
|
||||
Linux builds support Ubuntu 20.04 or later on amd64 and arm64. Release packages
|
||||
use Ubuntu 20.04/glibc 2.31 as their compatibility baseline. Install the base
|
||||
build dependencies first:

## Development and feedback
|
||||
# Ubuntu 20.04's CMake 3.16 is too old for Slint 1.17.
|
||||
python3 -m pip install --user cmake==3.31.6
|
||||
export PATH="$HOME/.local/bin:$PATH"
|
||||
```

|
||||
- [iOS development](apps/ios/README.md): native build and physical-device checks.
|
||||
- [GUI architecture](docs/gui-architecture.md): desktop UI and platform organization.
|
||||

|
||||
Ubuntu 20.04's default GCC 9 lacks parts of the C++20 standard library needed
|
||||
by Slint's C++ API, so the commands above install GCC 10 and the configuration
|
||||
below selects it explicitly.

# Ubuntu 20.04 has no PipeWire 0.3 development package. Install the
|
||||
# header-only SDK used during compilation. Skip this when the distribution's
|
||||
# PipeWire 0.3 development packages are already installed.
|
||||
sudo ./docker/linux-build/install-pipewire-sdk.sh
|
||||
|
||||
xmake f -m release --USE_CUDA=false --cc=gcc-10 --cxx=g++-10 -y
|
||||
xmake b -vy crossdesk
|
||||
```
|
||||
|
||||
The amd64 binary is written to `build/linux/x86_64/release/crossdesk`; the arm64 binary is written to `build/linux/arm64/release/crossdesk`.
|
||||
|
||||
Example configuration with Wayland and DRM capture enabled:
|
||||
|
||||
```bash
|
||||
xmake f -m release --USE_WAYLAND=true --USE_DRM=true --USE_CUDA=false \
|
||||
--cc=gcc-10 --cxx=g++-10 -y
|
||||
xmake b -vy crossdesk
|
||||
```
|
||||
|
||||
Build a Debian package after compiling a release binary on the matching architecture:
|
||||
|
||||
```bash
|
||||
# amd64
|
||||
./scripts/linux/pkg_amd64.sh 1.0.0
|
||||
|
||||
# arm64
|
||||
./scripts/linux/pkg_arm64.sh 1.0.0
|
||||
```
|
||||
|
||||
The package scripts install the shared Slint runtime in the private `/usr/lib/crossdesk` directory, so users do not need to install `libslint_cpp.so` separately.
|
||||
PipeWire is not a mandatory runtime dependency. CrossDesk detects the host's
|
||||
PipeWire 0.3 runtime dynamically and can still use X11 capture (and DRM when
|
||||
enabled at build time) when it is unavailable.
|
||||
|
||||
### Common build options
|
||||
|
||||
```text
|
||||
--USE_CUDA=true/false: Enable CUDA hardware codec acceleration, disabled by default
|
||||
--USE_WAYLAND=true/false: Enable Wayland/PipeWire capture on Linux, disabled by default
|
||||
--USE_DRM=true/false: Enable DRM capture on Linux, disabled by default
|
||||
--CROSSDESK_PORTABLE=true/false: Build the portable variant, disabled by default
|
||||
--CROSSDESK_VERSION=xxx: Set the CrossDesk version
|
||||
|
||||
# Example
|
||||
xmake f --CROSSDESK_VERSION=1.0.0 --USE_CUDA=true
|
||||
```
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
xmake r crossdesk
|
||||
```
|
||||
|
||||
#### Development Without CUDA Environment
|
||||
|
||||
For **Linux developers who do not have a CUDA environment installed and want to enable hardware codec feature**, a preconfigured [Ubuntu 20.04 compatibility build image](https://hub.docker.com/r/crossdesk/ubuntu20.04) is provided.
|
||||
This image contains the required build dependencies and produces a single Linux package compatible with the glibc 2.31 baseline.
|
||||
|
||||
After entering the container, download the project and run:
|
||||
```
|
||||
export CUDA_PATH=/usr/local/cuda
|
||||
export XMAKE_GLOBALDIR=/data
|
||||
|
||||
xmake f --USE_CUDA=true
|
||||
xmake b --root -vy crossdesk
|
||||
```
|
||||
|
||||
For **Windows developers without a CUDA environment** installed, run the following command to install the CUDA build environment:
|
||||
```
|
||||
xmake require -vy "cuda 12.6.3"
|
||||
```
|
||||
After the installation is complete, execute:
|
||||
```
|
||||
xmake require --info "cuda 12.6.3"
|
||||
```
|
||||
The output will look like this:
|
||||
|
||||
<img width="860" height="226" alt="Image" src="https://github.com/user-attachments/assets/999ac365-581a-4b9a-806e-05eb3e4cf44d" />
|
||||
|
||||
From the output above, locate the CUDA installation directory — this is the path pointed to by installdir.
|
||||
Add this path to your system environment variable CUDA_PATH, or set it in the terminal using:
|
||||
```
|
||||
set CUDA_PATH=path_to_cuda_installdir:
|
||||
```
|
||||
Then re-run:
|
||||
```
|
||||
xmake f --USE_CUDA=true
|
||||
xmake b -vy crossdesk
|
||||
```
|
||||
|
||||
#### Notice
|
||||
If the client status bar shows **Disconnected** during runtime, please first install the client from the [CrossDesk official website](https://www.crossdesk.cn/) to ensure the required certificate files are available in the environment.

|
||||
|
||||
## Self-Hosted Server
|
||||
It is recommended to deploy CrossDesk Server using Docker.
|
||||
```
|
||||
sudo docker run -d \
|
||||
--name crossdesk_server \
|
||||
--network host \
|
||||
-e EXTERNAL_IP=xxx.xxx.xxx.xxx \
|
||||
-e INTERNAL_IP=xxx.xxx.xxx.xxx \
|
||||
-e CROSSDESK_SERVER_PORT=xxxx \
|
||||
-e COTURN_PORT=xxxx \
|
||||
-e MIN_PORT=xxxxx \
|
||||
-e MAX_PORT=xxxxx \
|
||||
-v /var/lib/crossdesk:/var/lib/crossdesk \
|
||||
-v /var/log/crossdesk:/var/log/crossdesk \
|
||||
crossdesk/crossdesk-server:v1.1.6
|
||||
```
|
||||
|
||||
The parameters you need to pay attention to are as follows:
|
||||
|
||||
**Parameters**
|
||||
- **EXTERNAL_IP**: The server’s public IP. This corresponds to **Server Address** in the CrossDesk client’s **Self-Hosted Server Configuration**.
|
||||
- **INTERNAL_IP**: The server’s internal IP.
|
||||
- **CROSSDESK_SERVER_PORT**: The port used by the self-hosted service. This corresponds to **Server Port** in the CrossDesk client’s **Self-Hosted Server Configuration**.
|
||||
- **COTURN_PORT**: The port used by the COTURN service. This corresponds to **Relay Service Port** in the CrossDesk client’s **Self-Hosted Server Configuration**.
|
||||
- **MIN_PORT / MAX_PORT**: The port range used by the COTURN service. Example: `MIN_PORT=50000`, `MAX_PORT=60000`. Adjust the range depending on the number of clients.
|
||||
- `-v /var/lib/crossdesk:/var/lib/crossdesk`: Persists database and certificate files on the host machine.
|
||||
- `-v /var/log/crossdesk:/var/log/crossdesk`: Persists log files on the host machine.
|
||||
|
||||
**Example**:
|
||||
```bash
|
||||
sudo docker run -d \
|
||||
--name crossdesk_server \
|
||||
--network host \
|
||||
-e EXTERNAL_IP=114.114.114.114 \
|
||||
-e INTERNAL_IP=10.0.0.1 \
|
||||
-e CROSSDESK_SERVER_PORT=9099 \
|
||||
-e COTURN_PORT=3478 \
|
||||
-e MIN_PORT=50000 \
|
||||
-e MAX_PORT=60000 \
|
||||
-v /var/lib/crossdesk:/var/lib/crossdesk \
|
||||
-v /var/log/crossdesk:/var/log/crossdesk \
|
||||
crossdesk/crossdesk-server:v1.1.6
|
||||
```
|
||||
|
||||
**Notes**
|
||||
- **The server must open the following ports: COTURN_PORT/udp, COTURN_PORT/tcp, MIN_PORT–MAX_PORT/udp, and CROSSDESK_SERVER_PORT/tcp.**
|
||||
- If you don’t mount volumes, all data will be lost when the container is removed.
|
||||
- Certificate files will be automatically generated on first startup and persisted to the host at `/var/lib/crossdesk/certs`.As the default certificates are self-signed and cannot guarantee security, it is strongly recommended to apply for a trusted certificate from a cloud provider, deploy it to this directory, and restart the service.
|
||||
- The database file will be automatically created and stored at `/var/lib/crossdesk/db/crossdesk-server.db`.
|
||||
- Log files will be created and stored at `/var/log/crossdesk/`.
|
||||
|
||||
**Permission Notice**
|
||||
If the directories automatically created by Docker belong to root and have insufficient write permissions, the container user may not be able to write to them. This can cause:
|
||||
- Certificate generation failure, leading to startup script errors and container exit.
|
||||
- Database directory creation failure, causing the program to throw exceptions and crash.
|
||||
- Log directory creation failure, preventing logs from being written (though the program may continue running).
|
||||
|
||||
**Solution:** Manually set permissions before starting the container:
|
||||
```bash
|
||||
sudo mkdir -p /var/lib/crossdesk /var/log/crossdesk
|
||||
sudo chown -R $(id -u):$(id -g) /var/lib/crossdesk /var/log/crossdesk
|
||||
```
|
||||
|
||||
### Server Side
|
||||
Place **crossdesk.cn.key** and **crossdesk.cn_bundle.crt** into the **/path/to/your/certs** directory.
|
||||
|
||||
### Client Side
|
||||
1. Click the settings icon in the top-right corner to enter the settings page.<br><br>
|
||||
<img width="600" height="210" alt="image" src="https://github.com/user-attachments/assets/6431131d-b32a-4726-8783-6788f47baa3b" /><br>
|
||||
|
||||
2. Click `Self-Hosted Server Configuration` button.<br><br>
|
||||
<img width="600" height="160" alt="image" src="https://github.com/user-attachments/assets/24c761a3-1985-4d7e-84be-787383c2afb8" /><br>
|
||||
|
||||
3. Enter the `Server Address` (**EXTERNAL_IP**), `Signaling Service Port` (**CROSSDESK_SERVER_PORT**), and `Relay Service Port` (**COTURN_PORT**) and click OK button.
|
||||
|
||||
4. Check the `Self-hosted server configuration` option and click the OK button to save the settings. If the server is using a valid (official) certificate, the process ends here and the client will show that it is connected to the server.
|
||||
|
||||
5. If the default certificate is used (skip this step if an official certificate is used), download the self-signed root certificate `api.crossdesk.cn_root.crt` from the server directory /var/lib/crossdesk/certs/ to the machine running the client, and install the certificate by executing the following command:
|
||||
|
||||
On Windows, open PowerShell with **administrator privileges** and execute:
|
||||
```
|
||||
certutil -addstore "Root" "C:\path\to\api.crossdesk.cn_root.crt"
|
||||
```
|
||||
Linux
|
||||
```
|
||||
sudo cp /path/to/api.crossdesk.cn_root.crt /usr/local/share/ca-certificates/api.crossdesk.cn_root.crt
|
||||
sudo update-ca-certificates
|
||||
```
|
||||
macOS
|
||||
```
|
||||
sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain path/to/api.crossdesk.cn_root.crt
|
||||
```

Procedure to add a virtual monitor to your system (Windows 10 Only!)
|
||||
|
||||
- Download our virtual display driver from https://www.amyuni.com/downloads/usbmmidd_v2.zip
|
||||
- Unpack the zip file to an empty folder, e.g. c:\temp\usbmmidd
|
||||
- Make sure you read the License.txt file as with any other software product
|
||||
- Open a command prompt window as Administrator (you cannot add a device to your system unless you "Run As Administrator")
|
||||
- Run the following commands:
|
||||
- cd c:\temp\usbmmid (or whatever destination folder you chose)
|
||||
- deviceinstaller64 install usbmmidd.inf usbmmidd (If you are on a 32-bit system, replace "deviceinstaller64" by "deviceinstaller")
|
||||
- Make sure you see the message that the drivers are signed by Amyuni Technologies Inc. This is a confirmation that the drivers went through Microsoft driver signing procedure and are virus free
|
||||
|
||||
- Starting with version 2, the virtual monitor supports the following display resolutions by default:
|
||||
|
||||
1024 x 768 pixels
|
||||
1360 x 768 pixels
|
||||
1440 x 900 pixels
|
||||
1600 x 900 pixels
|
||||
1600 x 1200 pixels
|
||||
1920 x 1080 pixels [Default Resolution]
|
||||
1920 x 1200 pixels
|
||||
2560 x 1440 pixels
|
||||
3840 x 2160 pixels
|
||||
|
||||
After the first step above is executed, you can modify the list of supported resolutions by changing the following registry key:
|
||||
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WUDF\Services\usbmmIdd\Parameters\Monitors
|
||||
|
||||
Up to 10 resolutions can be defined through this registry key. The keys should be named from "0" to "9". The (Default) registry value defines the default monitor resolution.
|
||||
|
||||
Note that the list of resolutions can also be found in the usbmmidd.inf file that accompanies the printer driver. The inf file should not be modified in any way, otherwise the virtual display driver digital signature is invalidated.
|
||||
|
||||
Once you are satisfied with the list of resolutions, you can activate the virtual monitor by running:
|
||||
- deviceinstaller64 enableidd 1
|
||||
|
||||
With version 2, rou can run this command multiple times to add up to 4 virtual monitors to your system.
|
||||
|
||||
The included batch file usbmmidd.bat runs these commands automatically and selects between the 32- or 64-bit version of deviceinstaller.
|
||||
If you are not comfortable opening a command prompt and entering these commands, right-click on usbmmidd.bat and "Run As Administrator."
|
||||
|
||||
That's it. You now have a high definition monitor in your Display Settings. You can change the display resolution, position the monitor, extend the desktop or do whatever you do with a real monitor.
|
||||
|
||||
To deactivate the virtual monitor, run the command:
|
||||
deviceinstaller64 enableidd 0
|
||||
If ou have added more than one monitor, you should run this command multiple times to remove all monitors.
|
||||
|
||||
to reactivate a virtual monitor:
|
||||
deviceinstaller64 enableidd 1
|
||||
|
||||
To completely remove the drivers from your system, you can either go through the Device Manager and uninstall "USB Mobile Monitor Virtual Display", or run the commands:
|
||||
deviceinstaller64 stop usbmmidd
|
||||
deviceinstaller64 remove usbmmid
