我们的工作空间灵活，所有的工作场所都相同，但一个屏幕可能在左侧而不是右侧有 DVI 等，所以我需要更改输出，但屏幕尺寸和位置始终相同。
我的问题是，我中间有一个 2560x1600 的大屏幕，这个大屏幕的两侧各有一个 1920x1200 的屏幕。
每天上班的时候我通常只是写
xrandr --output "VGA-1-1" --mode 1920x1200 --output DP-2 --mode 2560x1600 --left-of VGA-1-1 --output DP-3 --mode 1920x1200 --left-of DP-2
但出于某种原因，如果我切换到另一个工作区，大屏幕可能就是 DP-3，所以我只是用它xrandr来找到正确的输出。
现在的问题是，nvidia 经常决定覆盖我的设置，因为通常每个窗口都有一个屏幕，所以它不认为这只是一个大屏幕，而是 3 个屏幕。但 nvidia 用所有 3 个屏幕制作了一个大型虚拟屏幕，因此左侧和中间工作正常，但当我将鼠标从中间移到右侧时，整个屏幕都会滚动，就像中间有一个大型虚拟屏幕一样……
有什么想法可以解决此问题吗？输出为：

如您所见，有些平移非常疯狂，并非每次都会发生，而且我没有办法修复此问题。重新启动也无济于事。

答案1
在某些情况下，我还添加了一些奇怪的平移。我最终使用了nvidia-settings而不是xrandr。语法更加混乱，但可以正常工作。
这是一个示例命令：
nvidia-settings --assign "CurrentMetaMode=DP-5: nvidia-auto-select @1680x1050 +0+0 {ViewPortIn=1680x1050, ViewPortOut=1680x1050+0+0, ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}, DP-2: nvidia-auto-select @1920x1080 +1680+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0, ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}, DP-1: nvidia-auto-select @1920x1080 +3600+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0, ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"
您可以使用 获取“当前元模式” nvidia-settings --query CurrentMetaMode。此输出中的显示名称与 中的不同xrandr，您可以使用 获取别名nvidia-settings --query dpys。
答案2
我刚刚重新使用我的旧戴尔笔记本电脑，它有 nvidia 适配器，最近将其切换到 nvidia 专有驱动程序。
xrandr --transform当我使用任何基于命令时，我开始看到类似的行为--fb。nvidia驱动程序强制执行一些平移设置，即使我没有使用明确设置它 --panning。
有时设置
--fb或--panning或两者可以解决问题，例如：xrandr --fb 6400x1600 --output "VGA-1-1" --mode 1920x1200 --panning 0x0 --output DP-2 --mode 2560x1600 --panning 0x0 --left-of VGA-1-1 --output DP-3 --mode 1920x1200 --panning 0x0 --left-of DP-2--panning 2561x1600加上 1px 然后恢复正常，--panning 2560x1600使 nvidia 驱动程序修复 FB 大小。
在某些情况下，我只是厌倦了 xrandr/nvidia 的错误组合，只能注销/登录。我有 GT218M [NVS 3100M]、nvidia-340、Xubuntu 16.04。
答案3
这似乎是 nvidia 的一个错误...我无法将 DP-0 放在中间，只能放在最右边。然后我通过在第一个显示器和 DP-0 之间留出 10px 的间隙来解决问题...这有效。
