After upgrade to bookworm: Keyboard layout

[Hans <hans.ullrich@loop.de>]

Dear list,

there is a little problem, I am trying to fix. 

After upgrade to bookworm the keyboard layout has changed from German to US 
(de to us).

I tried debian-reconfigure keyboard-configuration without success, also 
deinstalled and reinstalled both without success.

Doing "loadkeys de" is working, but after reboot it is English again. 

So I guessed, it is a initramfs issue and tried "setupcon -f -k" and "update-
initramfs -u" - also no success.

Also checked /etc/default/keyboard, the entry is correct (pc-105, de).

Some thing I noticed at bootup: When the kernel is started (or before kernel 
starts), I get a message like "/etc/console-setup/cached-utf8.tmp not 
correct", however, this message was seen before on bullseye, where everything 
was ok.

I suppose, something went wrong during upgrade, or during upgrade I missed 
something (as I am running an old NVidia card with unsupported driver by 
bookworm) as during upgrade phase the screen went crippy. 

Any more ideas, how it get be fixed? Of course I could enter the command 
"loadkeys de" as the last line of the startup scripts, but this solution is 
not satisfying me.

Thanks for reading it and any help.

Best regards

Hans
