![apt-get upgrade 之后,每当我在“显示”中更改某些内容时,显示器就会冻结](https://linux22.com/image/868834/apt-get%20upgrade%20%E4%B9%8B%E5%90%8E%EF%BC%8C%E6%AF%8F%E5%BD%93%E6%88%91%E5%9C%A8%E2%80%9C%E6%98%BE%E7%A4%BA%E2%80%9D%E4%B8%AD%E6%9B%B4%E6%94%B9%E6%9F%90%E4%BA%9B%E5%86%85%E5%AE%B9%E6%97%B6%EF%BC%8C%E6%98%BE%E7%A4%BA%E5%99%A8%E5%B0%B1%E4%BC%9A%E5%86%BB%E7%BB%93.png)
如果我打开显示器并更改任何内容,从分辨率到禁用或启用其中一个显示器,只要我单击,我的显示器就会冻结Apply
有时我仍然可以看到鼠标移动。然后我可以进入CTRL++来解冻监视器。当然,更改不会应用。ALTF1sudo service lightdm restart
这是在华硕 k56 上新安装的 Ubuntu Desktop 14.04.1,配有外接显示器。在今天升级之前,它运行良好。
我正在使用带有 nvidia 的 bumblebee。它们工作得很好,因为我可以运行 optirun glxspheres64 并在 Steam 上玩 CSGO。而且我可以更改显示而不会冻结。冻结开始了后这次升级。

和:
$ sudo apt-get install -f install
"0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded."
我认为这是这个错误。显然有相当多的人受到了影响。
答案1
现在似乎已经修复了。我xorg-edgers-ppa
从sources.list.d
目录中删除了:
sudo rm /etc/apt/sources.list.d/xorg-edgers-ppa-trusty.list.save
或更好:
sudo add-apt-repository --remove ppa:xorg-edgers/ppa
然后运行更新和升级:
sudo apt-get update && sudo apt-get upgrade
然后重新启动X
:
sudo service lightdm restart
现在我可以随心所欲地编辑显示设置了!谢谢你的帮助。
