我有两个显示器，每个显示器上运行两个不同的应用程序。例如。
- 监视器 A 应运行 chromium-browser
- 监视器 B 应该运行另一个 Chromium 浏览器
这应该在系统启动后运行。

startx /path/to/screen-1-app.sh -- :1 -layout Layout1 -config /path/to/displaylink.conf -nolisten tcp vt8 -novtswitch -sharevts &
displaylink.conf与 xorg.conf 相同：
screen-0-app.sh and screen-1-app.sh consist of

exec chromium-browser --user-data-dir=~/.chromium --window-size=1920,1080 --window-position=0,0 --kiosk --incognito http://www.youtube.com/watch?v=MRbI6LwLz94
another screen consist of different youtube link with same setup
问题是，我能够让一台显示器使用此设置工作。这意味着以下内容：
在 chromium 浏览器中播放 Youtube 视频 一个 startx 正在运行，但另一个显示器似乎空白，并且给出的错误是：

答案1
显示器和监视器不是一回事。
您正在尝试启动一个单独的 X 服务器并为每个监视器进行显示，但这不是您想要做的。
您想要启动一个具有 1 个显示器（:0）和两个监视器（:0.0和:0.1）的 X-server。
您应该有一个startx启动调用:0，并且脚本应该启动两个应用程序，并使用参数将其中一个移动到第二个屏幕--window-position。
如果您的显示器并排放置，并且第一个显示器的分辨率为 1920x1080，左上角为 0,0，则第二个显示器的左上角将是 1920,0。
答案2
Darth 说过。另外，在我们的文章中，xorg.conf您提到了monitor0（for screen0）和monitor1（for screen1），但您只monitor定义了一个部分，那就是monitor0。
我猜测未找到屏幕错误是因为 X 尝试查找monitor1但不存在。
