- Snap 版 Slack
slack --enable-features=WebRTCPipeWireCapturer在共享时会显示黑屏（或不显示黑屏） - 屏幕共享在 Xorg 上有效
- 屏幕共享适用于基于 Chromium 的浏览器 (Brave)
- Deb 版本的 slack slack-desktop-4.34.121-amd64 - 共享时黑屏
- 之前我使用的是 Fedora 37，内核是 6.12，gnome 43，slack 可以共享屏幕，所以这绝对是可行的
我在日志中看到，有一些子进程带有禁用 WebRTCPipeWireCapturer 的标志

答案1
较新的 slacks 明确禁用了 WebRTCPipeWireCapturer，但您可以通过直接编辑 JS 资源文件来解决这个问题。有一些完整性检查，并且需要相同的长度，否则 Slack 根本无法启动，但以下命令对我有效4.35.121。当然需要像以前一样传入命令行选项--enable-features=WebRTCPipeWireCapturer和/或将其放在桌面文件中。
sudo sed -i'.backup' -e 's/,"WebRTCPipeWireCapturer"/,"LebRTCPipeWireCapturer"/' /usr/lib/slack/resources/app.asar
桌面文件可以存在~/.local/share/applications/slack.desktop并且不会被更新破坏，但是每次更新后都需要重复 app.asar 修补。
答案2
根据这个线最新的 Wyaland 工作版本是 slack-desktop-4.29.149
可以使用以下命令下载、安装并运行工作屏幕共享
#Download
wget https://downloads.slack-edge.com/releases/linux/4.29.149/prod/x64/slack-desktop-4.29.149-amd64.deb
#install
sudo dpkg -i slack-desktop-4.29.149-amd64.deb
#run and check whether screen sharing works
slack --enable-features=WebRTCPipeWireCapturer
如果 .desktop 文件可以工作的话，请编辑它
nano /usr/share/applications/slack.desktop
