Question

I have Lubuntu 16.04. It is running on a Thinkpad X201 using Intel graphics devices (no Nvidia here).

After I watch a video on Youtube or use mplayer to watch a video, the screen flickers black right up to where my mouse cursor is.

It looks like this.

Logging out and logging back in resolves the issue.

Update: This only occurs when the mouse cursor is more than about an inch from the right hand side of the screen.

Any thoughts on how I can fix this?

Answer

Using

sudo apt-get install xserver-xorg-video-intel

fixed the issue for me.

However, now the mouse cursor disappears when waking from sleep. I haven't found a fix for this, but a work-around is to use Ctrl+Alt+F1 and then Ctrl+Alt+F7.
