我有兩個監視器，用於在每個監視器上運行兩個不同的應用程式。例如。
- 監視器 A 應該運行 chromium-browser
- 監視器 B 應該運行另一個 chromium 瀏覽器
這應該在系統啟動後運行。
下面是 xorg.conf

在運行等級 2 的初始化腳本中，我有：
startx /path/to/screen-0-app.sh -- :0 -layout Layout0 -config /path/to/displaylink.conf -nolisten tcp vt7 -novtswitch -sharevts &
startx /path/to/screen-1-app.sh -- :1 -layout Layout1 -config /path/to/displaylink.conf -nolisten tcp vt8 -novtswitch -sharevts &
displaylink.conf與 xorg.conf 相同：
screen-0-app.sh and screen-1-app.sh consist of
exec xterm -e xrandr -s 1920x1080 &
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
問題是，我可以讓一台顯示器使用此設定。這意味著以下內容：
在 chromium 瀏覽器中播放 Youtube 影片一個 startx 正在工作，但另一台顯示器似乎空白，它給出的錯誤是：

答案1
顯示器和顯示器不是一回事。
您試圖啟動一個單獨的 X 伺服器並為每個監視器顯示，這不是您想要做的。
您想要啟動一台具有 1 個顯示器 ( :0) 和兩個監視器 (:0.0和:0.1) 的 X 伺服器。
您應該startx調用一次 start up :0，並且腳本應該啟動兩個應用程序，並使用參數將其中一個移動到第二個螢幕--window-position。
如果您的顯示器是並排的，而第一個顯示器的解析度為 1920x1080，左上角為 0,0，那麼第二個顯示器的左上角將為 1920,0。
答案2
達斯說的話。另外，在我們的中，xorg.conf您引用了monitor0(for screen0) 和monitor1(for screen1)，但您只monitor定義了一個部分，即monitor0.
我的猜測是，「找不到螢幕」錯誤是因為 X 正在嘗試查找，monitor1但該畫面不存在。
