我刚刚安装了 Ubuntu 14.04,但我的屏幕分辨率设置得太低:我尝试添加一个新的,但我不断收到
xrandr: Failed to get size of gamma for output default

我试过 :
$ xrandr -q

================================================== ========================== 我昨天在我的 Ubuntu 12.04 上做了一个更新,由于1204_HWE_EOL 的问题,它破坏了我的屏幕分辨率
我回到 Ubuntu 14.04,获得良好屏幕分辨率的唯一方法是从恢复菜单开始,然后恢复启动。

我对决议有同样的问题。我正在使用 VirtualBox 并且分辨率只有一个分辨率选项。
一旦它重新启动,分辨率就已经修复了。
