Bug ID: 428603
Summary: Desktop effects are disabled after suspend. Can't set
rendering backend to opengl.
Product: kwin
Version: 5.20.1
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: effects-various
Assignee: kwin-bugs-n...@kde.org
Reporter: 842m...@gmail.com
Target Milestone: ---
SUMMARY
Desktop effects are disabled with opengl after suspend, and cannot be
re-enabled.
Sometimes this workaround fixes it. Go to compositor. Click the "re-enable
opengl detection" button. Switch rendering backend to opengl.
This is what happens when the workaround doesn't work. After I switch rendering
backend to opengl, kwin crashes again, and is reopened but desktop effects are
still disabled.
It seems to be an Nvida driver issue. I have the latest Nvidia driver
installed.
My laptop is an HP envy x360.
STEPS TO REPRODUCE
1. Suspend laptop
2. Wake it up from suspend
OBSERVED RESULT
Desktop effects are disabled and cannot be re-enabled with opengl as the
rendering backend.
EXPECTED RESULT
Desktop effects are enabled.
