SUMMARY OLED monitor brightness reverts to 0% whenever it is reconnected. STEPS TO REPRODUCE 1. Set brightness to a non-zero value 2. Enable HDR in Display Configuration (can also reproduce by turning monitor off and on again) OBSERVED RESULT The monitor's brightness level reverts from its current value (e.g. 50%) all the way down to 0%. This issue does not occur on Windows 11, which I run alongside Linux in a dual-boot configuration. EXPECTED RESULT Monitor brightness should not deviate from its current value if turned off and on again. Monitor brightness should ramp up when HDR is enabled - as it keeps reverting to 0%, this effectively renders HDR unusable on my system. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Slowroll KDE Plasma Version: 6.2.4 KDE Frameworks Version: 6.8.0 Qt Version: 6.8.0 ADDITIONAL INFORMATION
Hello, If any further info or log files are needed to troubleshoot, please let me know. Thank you!
When you say "brightness", do you mean the brightness slider in Plasma, or a setting on the screen itself?
(In reply to Zamundaaa from comment #2) > When you say "brightness", do you mean the brightness slider in Plasma, or a > setting on the screen itself? It seems like both are changing. I just booted up my system for the first time today and the brightness changed on both the monitor and the brightness slider without any input from me.
Okay, that's really odd. What version of Plasma are you on now? If you change the brightness in Plasma, does the monitor brightness change as well? (with HDR and without are different, please test both) Please turn HDR off, set brightness to 100% on the monitor and in Plasma, then run > killall org_kde_powerdevil; WAYLAND_DEBUG=1 /usr/libexec/org_kde_powerdevil 2>1 | grep brightness and enable HDR, and then paste the output of that command here. Afterwards, if you put POWERDEVIL_NO_DDCUTIL=1 into /etc/environment and reboot, does the issue still happen?
As of the latest OpenSUSE updated, I'm on version 6.3.2 - since this update things have improved slightly, but brightness still doesn't appear to be functioning correctly. The brightness keeps the correct brightness at boot up and I'm no longer experiencing brightness changes when I disconnect/reconnect the monitor. However, the HDR issue still remains. But to answer the questions from your comment: > If you change the brightness in Plasma, does the monitor brightness change as well? (with HDR and without are different, please test both) Changing brightness in Plasma changes the monitor brightness, and this seems to be the case both with and without HDR. > Please turn HDR off, set brightness to 100% on the monitor and in Plasma, then run > killall org_kde_powerdevil; WAYLAND_DEBUG=1 /usr/libexec/org_kde_powerdevil 2>1 | grep brightness > and enable HDR, and then paste the output of that command here. Unfortunately this command just hangs on my system and doesn't provide any output. > Afterwards, if you put POWERDEVIL_NO_DDCUTIL=1 into /etc/environment and reboot, does the issue still happen? The issue still occurs even with POWERDEVIL_NO_DDCUTIL=1 unfortunately.
Sorry, my mistake. It does look like the command dumped its output to a text file in my home directory: [1025393.091] {Default Queue} -> wl_display#1.get_registry(new id wl_registry#2) [1025393.488] {Default Queue} ->

So the command line output shows that powerdevil sees the screen as having brightness set to 100%, and then changes it to the saved value of 50%. Nothing unusual there. It is possible that your monitor has separate brightness settings for HDR and SDR? Mine does; so if it was set to 0% in HDR mode, switching to SDR and then back to HDR would reset it back to 0%
