Xrandr 添加了奇怪的虚拟屏幕尺寸和平移

Mar*_*ius 5 xrandr display nvidia multiple-monitors display-resolution

我们在工作中拥有灵活的工作空间，所有工作场所都是相同的，但一个屏幕可能在左侧而不是右侧有 DVI 等，因此我需要更改输出，但屏幕尺寸和位置始终相同。

我的问题是，中间有一个 2560x1600 的大屏幕，这个大屏幕的每一侧都有一个 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

但由于某种原因，如果我切换到另一个工作区，大屏幕可能会变成 DP-3，所以我只是用来xrandr寻找正确的输出。

现在的问题是，很多时候，nvidia 决定覆盖我的设置，因为通常我每个窗口上都有一个屏幕，所以它不认为它只是一个大屏幕，而是 3 个屏幕。但是nvidia制作了一个包含所有3个屏幕的大虚拟屏幕，因此左侧和中间工作正常，但是当我将鼠标从中间移动到右侧时，整个屏幕会滚动，就像您在其中只有一个大虚拟屏幕一样中间...

我有什么想法可以解决这个问题吗？输出为：

正如你所看到的，有些平移是疯狂的，它并不是每次都会发生，而且我没有办法解决这个问题。重新启动也没有帮助。

在某些情况下我还添加了一些奇怪的平移。我最终使用nvidia-settings而不是xrandr. 语法更加混乱，但它有效。

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显示名称不同xrandr，您可以使用获取别名nvidia-settings --query dpys。

我刚刚回来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的命令时，我开始看到类似的行为--fb。nvidia驱动程序强制进行一些平移设置，即使我没有使用明确设置它 --panning。

有时设置--fb或--panning两者都可以解决问题，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额外 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，只是注销/登录。我有 GT218M [NVS 3100M]、nvidia-340、Xubuntu 16.04。
