Bug ID: 499789
Summary: Setting an ICC profile in Display Configuration causes
screen to blank
Classification: Plasma
Product: kwin
Version: 6.3.0
Platform: Neon

Status: REPORTED
Severity: normal

ICC file used for testing
SUMMARY
When setting an ICC profile in system settings, when hitting Apply the screen
will go blank. Exiting/relogging in or rebooting does not fix this. The only
way to resolve is to rename the ICC file and restart plasmashell.
I thought this might be just a Neon thing, and mentioned it briefly in KDE
discussions. But, I did this on fresh installs of Neon-testing (VM),
Neon-unstable (VM), and Arch with kde-unstable packages enabled to get plasma
6.3.0 (physical hardware, nvidia-570 drivers). All three did the same thing.
STEPS TO REPRODUCE
1. In System Settings - Display Configuration, set a path to an ICC profile
2. Click Apply.
OBSERVED RESULT
Screen goes blank and cannot recover until ICC profile is renamed and
plasmashell is restarted.
EXPECTED RESULT
ICC profile is applied and the screen does not go blank.
SOFTWARE/OS VERSIONS
Linux: 6.8.0-53-generic on neon-testing, 6.11.0-17-generic on neon-unstable,
6.12.12-1-lts on Arch
KDE Plasma Version: 6.3.0, 6.3.80 on neon-unstable
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Graphics Platform: Wayland
ADDITIONAL INFORMATION
Attached is the ICC profile I used in the tests. It works fine on Plasma 6.2.5,
on Neon, Fedora, and Arch. Just want to eliminate it as an issue.
If any more information can be gathered, let me know how I should go about it
and I will do the tests again.
