Bug ID: 413269
Summary: Freeze on system-resume caused by kwin and amdgpu
driver
Product: kwin
Version: 5.16.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: bakarichar...@outlook.hu
Target Milestone: ---
This is a well investigated bug by me.
Problem: a black screen freeze occurs by suspend-resume process
Ubuntu version: Kubuntu 19.10 with default plasma (5.16.5), or the backported
5.17
Kernel version: default 5.3.10 or the mainline 5.4.0rc3
xserver-xorg-video-amdgpu: 19.* or the newest from git, the !18.0.1-1 works
well!
This freeze can be reproduced only if opengl 2.0 or 3.1 compositor is enabled
in Plasma settings. Xrender is OK however I don't like screen tearing.
On Ubuntu 19.10 Gnome desktop (X based) this doesn't occur even if the Gnome's
compositor is enabled. (I don't know what is the default one there but I
haven't disabled it)
I think this is a Kwin / amdgpu driver related bug because of the
differentiation. These can be fixed even in Kwin/opengl compositor not just in
the amdgpu driver or in kernel.
One possible solution: disable opengl compositor somehow by suspend and
re-enable it after login. Use fe.: Xrender before login / before the system
restored from suspend.
