问题描述
我刚刚安装了 ubuntu 14.04，鼠标现在在我的两个屏幕之一上闪烁。另一个屏幕没有任何闪烁。我之前使用的是ubunutu 13.10，没有任何问题。
-
如果我禁用正常工作的屏幕，第二个屏幕将停止闪烁并开始正常工作。
-
如果我禁用闪烁的屏幕，另一个屏幕将继续正常工作。
我已经尝试过这里找到的解决方案：
我的显示设置如下：
我正在使用 X.Org X Server - Nouveau display driver from xserver-xorg-video-nouveau (open source) 驱动程序。如果我尝试切换到专有的 nvidia 版本，然后单击 Apply Changes 按钮，它就会开始并需要永远完成，更改似乎永远不会应用。

最佳办法
将缩放因子从 1x1 更改为 0.9999x0.9999 对我来说很有效
xrandr --output eDP-1 --scale 0.9999x0.9999
