Title:
  i915 - after return from suspend display is flickering

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Test this with Ubuntu 20.04 (Mate) beta installer.
  Kernel is 5.4.0-21 #25 (if I remember right).
  All works fine, but after returning from suspend the display is flickering.
  For the installer / USB stick usage that might not be a problem, but the same 
behaviour in a normal environment would be a no go (for using suspend)

  Graphics is driven by an Intel Skylake core-m5 processor.
