KDE6 Upgrade - 6.9 Kernel SDDM & Shortcut issue

after the upgrade I was able to get one of my KDE system to work (reasonably) …
following problems still need to be resolved:
My own shortcuts (about 50) are shown under keyboard section but no longer work …
so I deleted the old entry (own shortcuts is no longer an independent group) and tried to import a previous export, but that doesn’t work either.

can wait
The new 6.9 kernel causes problems on boot the system shows loading screen but the sddm screen is not displayed, the previous kernel works & also LTS kernel.

OK, the kernel sddm problem was probably caused by the remaining plymouth stuff, reboot works!
The exported shortcuts are unusable w/ KDE6, so I have to recreate all my own shortcuts.
