Okay, I found out some important things. What I did is to reinstall dapper, activate all repositories in /etc/apt/sources.list (including multiverse) and made an update of dapper.
After a reboot I then changed all "dapper" into "edgy" in the sources.list and updated the whole system once again. There were a few question during that update that I all answered with "yes". Also, I deleted "splash" and "quiet" in the /boot/grub/menu.lst After a reboot the system came up correctly, including the desktop. The system could also be correctly shutdown/reboot. But then, adept updater showed that there were updates available. I ran through all of them, made a reboot and then the error showed up: I could enter the password but then the laptop ran into the known issue. Also, a shutdown/reboot isn't no longer possible. As attachment, you can see what packages are concerned after the correct bootup of edgy but before running the adept-updater.
