[求助]Ubuntu14.04双显示器,主显示器鼠标闪烁

[jecopeng]

我的电脑是nVidia 310M和Intel双显卡,并且连接了两个显示器共同工作,无论哪个显示器作为主显示器,都会出现鼠标闪烁的情况,请问如何解决呢?
设置中并没有出现未知显示器,禁用未知显示的做法不可行呢.
求大神解决,谢谢!

把下面指令 複製 貼進終端機 執行
1. uname -r
2. sudo lspci -knn
3. sudo lshw -numeric -class video
4. sudo ubuntu-drivers devices
5. nvidia-settings --glxinfo | grep "OpenGL version string"
把結果全部直接 選取/複製/貼上來
