            Bug ID: 93711
           Summary: [bdw edp] i915 screen flickering after new start
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel

Created attachment 121027
  --> https://bugs.freedesktop.org/attachment.cgi?id=121027&action=edit
output of the lspci -vvv

to differentiate from the bug #91393 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

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.
