Bug ID: 490016
Summary: Black Screen After Login with HDR and 5120 x 1440
Classification: Plasma
Product: kwin
Version: 6.1.1
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: goldfish...@runbox.com
Target Milestone: ---
SUMMARY
When display settings are set to a resolution of 5120 x 1440 @ 120Hz, and HDR
is enabled, after logging out or shutting down the computer, upon logging in, a
black screen is presented. It plays the login chime and a cursor is present,
but nothing else.
This does not happen when these options are selected seperately, only when
together. So 5120 x 1440 without HDR works fine, and any other resolution with
HDR enabled also works fine.
It should be noted that under 'Display Configuration', when selecting these
options simultaniously, they do not apply. I need to first set one, apply, and
then set the other, and apply. System will work afterwards, until logging out
and logging back in.
STEPS TO REPRODUCE
1. Set display resolution to 5120x1440;
2. Enable HDR;
3. Log out;
4. Log in;
OBSERVED RESULT
Black screen after login;
EXPECTED RESULT
Desktop is displayed;
