I am answering myself. As I could not find any reason causing this behaviour, I installed the system new. So formatted all partitions, except the one mounted to /home and installed debian/trixie new with profiles "KDE", "XFCE" , "Desktop" and "LXQT". Then tested and everything was working fine, even KDE/Plasma_6. Then reinstalled all packages I had former installed (the list was created by dpkg --get-selections) and after this some packages from some third party repos. Everything was working fine, except the webcam was activated at boot. This took me a long time to explore the reason, but lastly it was the package "motion", where (I suppose), the config had changed, so that the service was started by default. Deinstallation and purging of this package was the trick. ( Some people in this forum or somewhere else told about, that after upgrade to trixie the webcam was no more working and its LED was switched on. Maybe this little hint may help.) Now everything is working well on my laptop. The desktop computer with the NVidia graphics card appears still a little buggy. When starting the windowmanager (no matter which), X is freezing for about 10-20 seconds. Then it is working well. I changed the proprietrary driver from the NVidia website to the debian packages (from 570.X to 550.X). The GPU is a GT960, which runs Tesla-driver. So far so well. Trixie is working well, a little pity is the missing of some packages like linphone-dekstop and xhydra (aka hydra-gtk), but this is not a big mess. Last but not least: I could not find out, what was the reason for these issues. I am sure, I did nothing wrong during full-upgrade, because I did it almost four times to make sure, doing everything correct. Personally I believe, some cachefiles or some libs or even some configurations could have been not upgraded and could have interfered - don't know. I suppose, with the formatting and fresh installation I got rid of this. So it is all fine! Thanks for all your help and happy hacking! Best regards Hans
