Bug ID: 485403 Summary: Enabling HDR freezes system Classification: Plasma Product: kwin Version: 6.0.3 Platform: Manjaro OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: kde.backboned...@aleeas.com Target Milestone: --- SUMMARY I clicked ‘enable HDR’ on one of my monitors and something broke. The whole system froze up and the HDR monitor went black. If I reboot it freezes right after I login. If I unplug that monitor or start in X11 instead of Wayland then everything is fine. Plugging the HDR monitor in while I’m logged into a Wayland session also freezes everything. How can I disable the HDR setting? The monitor doesn’t show in System Settings whilst its unplugged so I’m hoping theirs some way to fix it on the CLI. The only place I’ve found HDR referenced is .config/kwinoutputconfig.json. I set HDR to false but after reboot it’s set to true again. I also tried deleting .config/kwinrc and .local/share/kscreen but no luck. STEPS TO REPRODUCE 1. Enable HDR on Monitor in System Settings > Display OBSERVED RESULT - HDR monitor goes black - Other monitor now unresponsive. - System works if monitor is not plugged in on start up - Cannot disable HDR setting in UI without the monitor plugged in. If I plug in the monitor then the system freezes. - Monitor also does not appear in kscreen-doctor when unplugged. EXPECTED RESULT - System does not freeze - Saved monitor settings can be modified or cleared even when disconnected. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.3 ADDITIONAL INFORMATION Lemmy Community Discussion https://lemmy.kde.social/post/1104524 Similar to https://bugs.kde.org/show_bug.cgi?id=483600 but if I use only the HDR monitor it still has the issue. Fixed by - Ctrl + Alt + F3 to go into terminal - Set `HighDynamicRange` and `WideColorGamut` to false in ~/.config/kwinoutputconfig.json - Execute `plasmashell --replace` - Reboot, Login, Reattach HDR Monitor - AMD based Desktop - Nvidia GPU - Dual Monitor Setup (BenQ and Gigabyte) - HDR setting enabled on Gigabyte. - Installation is approximately 4 years old. -- You are receiving this mail because: You are watching all bug changes.
