I've a similar issue and maybe it's also related to https://bugs.kde.org/show_bug.cgi?id=495106 (not my issue). Similar setup as the reporter: Operating System: Archlinux KDE Plasma Version: 6.2.1 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.11.4 Graphics Platform: Wayland Processors: AMD Ryzen 9 3900X 12-Core Processor Memory: 128 GiB of RAM Graphics Processor: AMD Radeon RX 6700 XT Besides that the brightness control sooner or later "disappears". So you can only control the "Night control" anymore but the "Brightness" slider disappears. But so far I wasn't able to figure out when this happens. Still relevant on 6.3.91. Brightness resets only on primary monitor(one of 4). Also, it resets after some time in locked state. Brightness control sometimes shows only 2 monitors out of 4 (In reply to dannkunt from comment #2) > on 6.3.91 I mean 6.2.91. There are no edit button Created attachment 178462 [details]

Brightness after turning screen on
Brightness is yet again broken after updating from 6.2.5 to plasma 6.3.0. Monitor brightness resets back to 100% after turning off screen and then turning it back on. Issue only affects primary screen thou for some reason. Primary screen is connected through displayport and secondary screen is connected with club 3D displayport to dvi-dl active adapter. It doesn't matter if i set brightness through monitor settings or plasma control panel it always resets back to 100% if i turn screen off and then on. Reboot doesn't reproduce this issue. Operating System: CachyOS Linux KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2 Kernel Version: 6.13.2-2-cachyos (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 9700X 8-Core Processor Memory: 31.0 GiB of RAM Graphics Processor: AMD Radeon RX 7900 XT *** Bug 500337 has been marked as a duplicate of this bug. *** I can't reproduce this on git-master or 6.3.1 Laptop, connected to external display Set laptop to 60% and monitor to 50% Rebooted, and both screens retained the same brightness settings Also tried power cycling the monitor, brightness was retained It makes me wonder what about the monitors that *are* affected are different than the ones that aren't Resetting the version field The ddcutil version is also relevant here; what version is everyone using? AFAIK 2.2.0 is supposed to fix a lot of these issues. ddcutil 2.2.0 here on both machines Duping to Bug 494408, which is about a code change in Plasma 6.3.2 fixing this. If you have 6.3.2 and it doesn't fix it, please also make sure you have ddcutil 2.2.0. If you have both Plasma 6.3.2 and ddcutil 2.2.0 and it's still not fixed, please open a new bug report about it and we'll track that slightly different issue there. Thanks everyone! *** This bug has been marked as a duplicate of bug 494408 *** |
