Hi there, the latest (2?) updates broke my build ;-).
Environment:
stable, KDE Plasma, Kernel 5.8+5.9 tested, fresh user tested, intel & nvidia
Problem:
After login with SDDM akwallt prompts for some password and the story ends here.
Windows just get rendered when changed, no redraw for leftovers. No taskbar, nothing. Yakuake works. Opened Windows are fixed and can’t neither be moved nor resized.
Very similar to a black screen with mouse cursor only.
I couldn’t find this much in the logs, so bash debug help is welcome.
What I was able to extract and think could be relevant from the started syslog KDE app was:
14:38 sudo - Connecting to depricated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
14:38 kcminit_startup - QDBusConnection: error: could not send signal to service “” path “/home/<user_redacted>/.kde4/share/config/kdeglobals” interface “org.kde.kconfig.notify” member “ConfigChanged”: Invalid object path://home/<user_redacted>/.kde4/share/config/kdeglobals
14:38 keded5 - kf.kded: Could not load kded module “gtkconfig”:“Cannot load library /usr/lib/qt/plugins/kf5/kded/gtkconfig.so: libkdecorations2private.so7: cannot open shared object file: No such file or directory)” (library path was:"/usr/lib/qt/plugins/kf5/kded/gtkconfig.so")
14:38 kded - QDBusConnection: name ‘org.kde.kglobalaccel’ had owner " but we thought it was ‘:1.13’
14:38 kded5 - plasma-nm: Unhandled active connection state change: 1
14:38 kwalletd5 - Application ‘“kded5”’ using kwallet without parent window!
I had thermal monitor in KDE in .local but removed it.
I was only able to get it up and running again with restoring a timeshift BTRFS snapshot.
Neither a kernel change brought improvement nor a fresh user - so the problem does NOT locate within home space.
Also a change to testing was fruitless.
Any help would be appreciated, as I don’t see a way to install new (needed) programms without update, which broke my system many times. I learned to love timeshift ;-).
