Public bug reported:
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'

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.
