![容器:无法启动 mutter(作为带有 gnome 会话的无头 Wayland 合成器)](https://linux22.com/image/205984/%E5%AE%B9%E5%99%A8%EF%BC%9A%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8%20mutter%EF%BC%88%E4%BD%9C%E4%B8%BA%E5%B8%A6%E6%9C%89%20gnome%20%E4%BC%9A%E8%AF%9D%E7%9A%84%E6%97%A0%E5%A4%B4%20Wayland%20%E5%90%88%E6%88%90%E5%99%A8%EF%BC%89.png)
我想做的是
- 一个容器(最好是 OCI 容器),无需将主机会话管理器接口暴露在“其中”即可工作,并且
- 运行 Wayland 合成器
- 有一个 >= gnome40 会话,其中包含所有 UI 元素
- 允许通过 RDP 或 VNC 进行远程显示和交互
因此,这分别规定/建议作为工具:
podman
mutter
(这就是 Gnome 想要的)gnome-shell
gnome-remote-desktop
,随 Gnome42 一起提供
我目前正在做的是
podman run -it --rm -p 9999:9999 ubuntu:22.04
# ^---------------------------------Interactive
# ^-----------------------------Don't keep state after finishing
# ^------------------------We'll need a port fwd into the container for RDP/VNC
# ^------------Not a great fan of Canonical, but 22.04 brings Gnome42

不太确定从这里去哪里。我应该直接启动 gnome shell 吗?
# fresh container to avoid any conflicts
root@7396d1bb8693:/> gnome-shell --no-x11 --wayland --headless --virtual-monitor 1600x1000

也不行。
- 如何在非特权容器中启动无头 gnome wayland 会话?
答案1
我设法在 GitHub 操作上完成以下工作(不确定它是否像 OCI 一样没有特权,所以也许它不能完全适合你):
run: |
sudo apt-get install mutter dbus-x11;
dbus-launch --auto-syntax > dbus-env;
source dbus-env;
mutter --no-x11 --headless --virtual-monitor 1920x1080 &
这source dbus-env
将为进一步的进程连接到显示器设置正确的环境变量。
