通过 VGA 打开多台显示器时系统崩溃

通过 VGA 打开多台显示器时系统崩溃

我试图让多屏幕(双屏)在通过 VGA 电缆连接的第二台显示器上工作,但每当我按“屏幕切换”打开复制模式时,系统就会崩溃。基本上,我无法让两个显示器都亮起,因为系统会崩溃。我必须说 HDMI 工作正常,但 VGA 给我带来了问题。我还尝试使用该命令xradr,所有输出都工作正常,因为它们已连接,但当我运行时,xrandr --output LVDS --primary --auto --output VGA-0 --right-of LVDS --auto只有一个屏幕工作,而另一个不工作。

下面那应该是错误日志
