Created attachment 170233 [details] current power saving settings SUMMARY If I leave my computer idle for some time, power saver kicks in and redueces screen brightness, eventualy turning off the screen. After waking up, the brightness stays at 30%, instead of going back up to 100%, even though the brightness indicator in the system tray shows 100%. STEPS TO REPRODUCE 1. Leave the coputer idling for X amount of time (10 min default) 2. Wait for the screen to turn off 3. Move the mouse or press any key on the keyboard to turn it back on OBSERVED RESULT The screen comes back at around 30% brightness EXPECTED RESULT Screen should return to previously set brightness value (in my case, 100%) SOFTWARE/OS VERSIONS: OS: Arch Linux x86_64 Kernel: Linux 6.9.3-zen1-1-zen KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 Graphics Platform: Wayland HARDWARE INFORMATION: Motherboard: MS-7C37 CPU: 12 × AMD Ryzen 5 5600X 6-Core Processor GPU: AMD Radeon RX 6600M ADDITIONAL INFORMATION LG 29WK600 Monitor connected through DisplayPort. This seems related to https://bugs.kde.org/show_bug.cgi?id=476540 but happening on a newer version of Plasma
I have the same issue on openSUSE Tumbleweed. GPU: Radeon 6700 XT Monitors: DELL S2340L connected via HDMI and GIGABYTE G27Q connected via DisplayPort. G27Q also has HDR enabled.
I also can change brightness via system tray applet, but it is often out of sync with actual brightness level.
This is a thing we already have an open bug report, right Jakob? I can't find one though.

Yes, looks like it. Thanks. *** This bug has been marked as a duplicate of bug 476540 ***
