升级至 20.04 后三台显示器设置失败

编辑

没有备份，没有怜悯。我重新安装了整个系统，清除了安装。没有区别。看来这个问题要么是我的设置所特有的，要么与 Ubuntu 20.04 有关。

原来的

升级到 20.04 后，我的三显示器设置坏了。我现在只能激活主显示器。我正在运行 nvidia-driver-440 包。

如果我将刷新率设置为 144 Hz，主显示器分辨率将翻倍至 3840x1080 像素。我必须滚动才能到达屏幕的最左端或最右端。如果我将其设置为 60 Hz，分辨率将重置。

此外，我无法通过 ubuntu 显示设置或 nvidia-settings 打开其他两个屏幕。它们被列为显示器，我可以在菜单中激活它们，但应用配置后，它会重置为仅主显示器。显示器退出省电模式一次，然后恢复省电模式（电源按钮闪烁）。在启动过程中，所有屏幕都显示启动屏幕。

所有显示器都插入 nvidia 卡。

很高兴得到任何帮助。
