Bug ID: 110117 Summary: Waking from Suspend causes screen to appear with grey static (like a TV with no signal) Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: stein12c@gmail.com
Created attachment 143671 --> https://bugs.freedesktop.org/attachment.cgi?id=143671&action=edit journalctl -b -1 -k
I am running Ubuntu 18.10. This is the PH517-61 Acer Predator Helios 500 with the Ryzen processor. I have temporarily disabled suspend. If I do let the laptop suspend and then hit the keyboard I get what appears to be a TV with no signal. At this point I manually power down and then power up again and am able to view things on screen.
I have reported this downstream here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813820
in log.txt I have attached the output of 'journalctl -b -1 -k'

This is a Vega 56 card but here is what I get with this command: lspci -k | grep -EA3 'VGA|3D|Display' 08:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

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.
