I have white or black horizontal striped lines on my windows.

lspci :

root@ubuntu15:~# lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated Graphics Controller (rev 02)
    Subsystem: Elitegroup Computer Systems Device 2636

How to fix it ?

Thank you.

Here comes screenshots.

Crappy lines

Looks like bug #1393205 - Intel q35 bug on Ubuntu 14.04 (Screen Artifacts) which is fixed by upgrading to a later kernel (3.19 or later). Make sure you have latest drivers installed as well (sudo apt-get update && sudo apt-get dist-upgrade).

  • Try installing the latest drm-nightly kernel and xserver-xorg-video-intel from xorg-edgers - and if it still occurs ask the Intel developers on the upstream bug.

  • I installed the last drm 4.4.0-994 but it doesn't boot. And my xserver-xorg-video-intel is also the last.

  • What was the error? Perhaps you can try mainline 4.4? Though 4.2 is pretty recent anyway.. Report a new bug on freedesktop.org and mention that it's the same as bug #45092 (you should be able to add a link in the "see also" field). Since 3.19 is specifically mentioned as being fixed, you might also want to give that a try, there could be a regression.

  • It looks like the fix only works for gen4 chipsets but your q35 is gen3. It's a long shot but try this patch.
