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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1813820 Title: Waking from Suspend causes screen to appear with grey static (like a TV with no signal) Status in linux package in Ubuntu: New 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 -- Logs begin at Sun 2019-01-27 22:00:42 CST, end at Mon 2019-01-28 21:01:54 CST. -- Jan 28 20:40:33 craig-Predator-PH517-61 kernel: tpm_crb MSFT0101:00: can't request region for resource [mem 0xdf775000-0xdf778fff] Jan 28 20:40:42 craig-Predator-PH517-61 spice-vdagent: Cannot access vdagent virtio channel /dev/virtio-ports/com.redhat.spice.0 $ uname -a Linux craig-Predator-PH517-61 4.18.0-13-generic #14-Ubuntu SMP Wed Dec 5 09:04:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux This is a Vega 56 card but Kubuntu seems to think it is a Vega 64: $ lspci -k | grep -EA3 'VGA|3D|Display' 08:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
