Title:
Display corruption on intel haswell Macbook Air
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am experiencing frequent display corruption after installing Ubuntu 17.10
on my 2013 Macbook Air (version 6.2).
The display flickers with a corrupted image for a brief second before
returning to normal.
Booting with nomodeset removes the corruption. I have tried some of
the workarounds listed on the archwiki for screen flickering on intel
(https://wiki.archlinux.org/index.php/intel_graphics#Screen_flickering).
They did not work for me.
Also. I don't think this is related to any specific applications,
because I get the corruption regardless of distro and desktop
environment.
Even though the corruption happens regularly (at least once every 10
secons), I have also found a way to manually trigger it. If I run lm-
sensors, the display will show major corruption for a second.
