Ubuntu apt 升级 = 1 个显示器卡在 1024x768(同一显卡)

我有一块带 4 个 DVI 输出的显卡。在升级 apt 之前,我的分辨率全部是 1920x1080……现在我只能在一个分辨率上卡在 1024x768 了。

以下是 的输出xrandr

找到了解决方案:运行 xrandr 列出您的显示器(即,为我返回 DisplayPort-1、DisplayPort-2、HDMI-0、HDMI-1)

然后通过以下方式添加所需的分辨率:xrandr --addmode DisplayPort-1 1900x1280

然后只需进入系统设置->显示并从下拉菜单中选择您的分辨率:)
