Created attachment 174546 [details] Screenshot SUMMARY Just upgraded to 6.2.0 from 6.1.5 on Tumbleweed and rebooted. The night light applet vanished from the system tray and I had to re-add it as a widget. Now it's separate from the system tray and it has no titlebar when opening it. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20241007 KDE Plasma Version: 6.2.0 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.3 Kernel Version: 6.11.2-1-default (64-bit) Graphics Platform: Wayland
Does clicking on the down arrow next to "de" not show "Brightness and Color"? That's the widget where night light should be.
Created attachment 174616 [details] Screenshot 2 On Fedora 40 with Plasma 6.2.0 (upgraded from 6.1.5) it's there, but not for my Tumbleweed installation, even when I set it to "Always show". I've also purged Plasma cache and rebooted, but it's still not visible. One difference between F40 and TW is at least Qt6.7.2 vs Qt6.7.3 if that should be relevant.
Another hint, powerdevil fails to start on the TW machine since 6.2: ``` systemd: Starting Powerdevil... org_kde_powerdevil[2968]: /usr/libexec/org_kde_powerdevil: symbol lookup error: /lib64/libpowerdevilcore.so.2: undefined symbol: ddca_stop_watch_displays systemd: plasma-powerdevil.service: Main process exited, code=exited, status=127/n/a systemd: plasma-powerdevil.service: Failed with result 'exit-code'. systemd: Failed to start Powerdevil. systemd: plasma-powerdevil.service: Scheduled restart job, restart counter is at 1. ```
``` systemsettings[9413]: kf.coreaddons: "Could not load plugin from /usr/lib64/qt6/plugins/plasma/kcms/systemsettings/kcm_powerdevilprofilesconfig.so: Could not load library /usr/lib64/qt6/plugins/plasma/kcms/systemsettings/kcm_powerdevilprofilesconfig.so: /lib64/libpowerdevilcore.so.2: undefined symbol: ddca_stop_watch_displays" ```
ddcutil is version 2.1.4-1.1 on TW
On Fedora 40 it's 2.1.2
I think from a UX POV it would be good if the applet were still shown, with an error hint when opened, that it requires powerdevil being running.
Probably a sane idea. Still, the original issue is pretty clearly a distro packaging bug. Can you open a new bug report for the requested improvement in error logging? Thanks!
