问题描述
我正在尝试在 docker 容器中启动 Weston。根据我的阅读，这应该是可能的，但它会劫持我的屏幕，我需要强制重启机器才能退出容器。
我有一个用于安装 weston 的 dockerfile。然后我以特权身份运行容器。

ENV GST_VAAPI_ALL_DRIVERS=1
workdir app
copY app/start.sh .
copY app/weston.ini .
copY app/app.js .
CMD ["node","app.js"]
app.js 依次根据 Arch wiki documentation 使用 /sys/class/drm 下的可用内容填充 weston.ini 文件。
最终的 weston.ini 文件位于 /etc/xdg/weston/weston.ini 下。我在使用 Ubuntu 20.04 的 VirtualBox VM 中工作，因此输出的名称和潜在的错误源可能？

设置 weston.ini 后，脚本尝试使用 start.sh 启动 weston 和 cog：
#!/bin/sh
service udev start < /dev/null
weston-launch --tty /dev/tty1 --user root &
sleep 5
cog $1
然而，在此之后我没有进一步，我从 atomic 和 repaint-flush 得到两个错误：
* Starting hotplug events dispatcher systemd-udevd [ OK ]
* Synthesizing the initial hotplug events (subsystems)... [ OK ]
* Synthesizing the initial hotplug events (devices)... [ OK ]
* Waiting for /dev to be fully populated... [ OK ]
