href="show_bug.cgi?id=91393">bug #91393</a> I'm creating a new one. It because I have
different symptoms and end solutions offered there do not help.
Here is a video to demonstrate the problem
<a href="https://www.youtube.com/watch?v=DZIR4qnfOH8">https://www.youtube.com/watch?v=DZIR4qnfOH8</a>
With the stock ubuntu 15.10 kernel version 4.2 this problem persists and
there's no way to get rid of it. With the current drm-intel-nightly kernel:
$ uname -a
Linux chrome 4.4.0-994-generic #201601112101 SMP Tue Jan 12 02:02:39 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux
the problem occurs only after a new boot. Then I need (almost blindly) login
into my system and start 'xset dpms force off' command once or several times
and then the flickering is gone even after I resume from the sleep.
