Mouse freezing by left edge on Ubuntu 16.04

Vladislav

I just installed ubuntu 16.04 and found that mouse pointer is like sticking to left edge of the screen.
It does not move if it is close to left screen edge.
When the speed of the mouse is small, it keeps to move a bit.
Did anybody have this problem??

Exactly the same here. But I'm using a freshly installed Fedora 26 KDE. When mouse is moved close to left edge of screen (10 to 40 pixels) it stops moving visually, but the desktop still gets updated events as though it has moved (detected by a tooltip that is displayed when the coordinates of events reach the "Start" button at the bottom). When the X coordinate slightly increases - moves to the right, the pointer jumps to current event coordinates instantly.

Hi Vlad,

The issue you are describing looks to me like the workaround for a known issue on the Intel GPU driver for Cherry Trail SoC which otherwise may cause thew system to freeze.

It seems odd but it actually solves a much worse problem.

Had the same problem until today on ubilinux.
While experimenting with tear free video output, I noticed that specifying Driver "intel" in Device section of /etc/X11/xorg.conf file fixes this problem for me.
Here is an example of minimal xorg.conf which should do the trick:

Section "Device"
    Identifier "Intel"
    Driver "intel"
EndSection

So far everything seems to work ok, will keep watching.
