Expected Behaviour:
I expect to continue to be able to use my machine normally and be able to see 
what is happening on screen.

Actual Behaviour:
Static on screen obscures everything.

  Waking from Suspend causes screen to appear with grey static (like a
  TV with no signal)

Status in linux package in Ubuntu:

Bug description:
  I am running Kubuntu 18.10. This is the PH517-61 Acer Predator Helios
  500 with the Ryzen processor. My first issue I need to deal with is
  Suspend. I have temporarily disabled suspend in the kcmshell5
  configuration. If I do let the laptop suspend and then hit the
  keyboard I get what appears to be a 1950s TV with no signal. At this
  point I manually power down and then power up again and am able to
  view things on screen.

  Running these commands I get this information:
  $ journalctl -b -g suspend
  Compiled without pattern matching support

  $ journalctl -b -p3

  This is a Vega 56 card but Kubuntu seems to think it is a Vega 64:
  $ lspci -k | grep -EA3 'VGA|3D|Display'

Vega 10 XT [Radeon RX Vega 64] (rev c7)
  Subsystem: Acer Incorporated [ALI] Vega 10 XT [Radeon RX Vega 64]
  Kernel driver in use: amdgpu
  Kernel modules: amdgpu

  $ glxinfo | grep "OpenGL version"
  OpenGL version string: 4.4 (Compatibility Profile) Mesa 18.2.2

  I will attempt to flesh this out more when I get home.
