Some more details on the PC with the heavy problems: The card is a GeForce 6100 nForce 430 (according to nvidia-settings). I removed the above mentioned GDM links, nothing changed. Even more: If I do a warm boot after logging out from KDE (and having no other choice, since I have only the black screen as alternative to the remaining text consoles), I finally end up with Bios beeping and a black screen (beep code indicates memory error - Award Bios, continuously beeeep, beeep, beeep... I have to turn off the computer, wait a few seconds, turn it on again. Then it comes up until after the boot splash - and hangs for about 20 seconds as described above, before X finally gets started.
I ran nvidia-xconfig again (which changed and re-arranged the xorg.conf), so I gave it another try. After the logout from KDE the same situation. This time I grabbed a console and had a look at the log files - and here's what I found in /var/log/syslog: Jul 23 20:15:14 nebo console-kit-daemon[6171]: WARNING: Unable to activate console: No such device or address Jul 23 20:15:14 nebo kernel: [39286.563103] Xorg[6575]: segfault at 00000009 eip 080c671b esp bff8cce0 error 4 Jul 23 20:15:14 nebo kdm[6570]: X server terminated: [0, 0, 0] Jul 23 20:15:14 nebo kdm[6570]: X server for display :0 terminated unexpectedly Jul 23 20:15:14 nebo kdm[6570]: Unable to fire up local display :0; disabling. looks like the video driver messes things up completely.

That looks like a real mess - all kind of drivers "unpacked", and even the nvidia-kernel package with the matching version number is only marked "un" and not "ii"? If I try to reconfigure it (dpkg --configure nvidia- kernel-96.43.05), dpkg says it cannot configure the package since it is not installed? I got curios, and looked with synaptic - most of the "un" listed packages are not even shown there! I tried to get thing in order: dpkg --configure -a dpkg -C both showed up nothing. Neither did "apt-get install -f".
