General Support - KDM stopped working

Titel: KDM stopped working
Hi, I did a dist-upgrade today and after it finished without errors, I did "init 5", but after a black screen I got back to command line. These are the messages shown:

Code:
Starting K display manager: kdm
Not starting X display manager (xdm): it is not the default display manager

I think a link to kdm were removed during d-u. Could you help me? Thanks Geschockt

When you start X manually with the "startx" command, what errors does xorg show?

Same thing happened to me last night. The fix was to "dpkg-reconfigure xserver-xorg" (which creates a new /etc/X11/xorg.conf file).

Well first you should try to reinstall KDM:
apt-get remove --purge kdm
apt-get install kdm

Then it should be working.

IIRC, last night's dist-upgrade installed a new version of xserver-xorg-core, and that's the issue here, not kdm.

Yes that is also a solution, if there are problems with kdm, the /etc/X11/xorg.conf is the root of the problem. Well the best way to avoid such probs is to make a backup of the xorg.conf file before updating xorg or installing Video Card drivers.

In my case, restoring a recent backup of "xorg.conf" (one from last Wednesday) did not help.

After last night's dist-upgrade, the X server wouldn't start, complaining about not being able to load the "pcidata" and "bitmap" modules. And if the X server won't start, then kdm won't start.

Perhaps what we need is a Kanotix guru to comment on this.

eco2geek, you could look for a prior version of xserver-xorg in /var/cache/apt/archives and reinstall it with dpkg -i. If all goes well, apt will replace it with a current version next time you dist-upgrade.

Oh, no need to do that. After the dpkg-reconfigure, X works fine. (As a matter of fact, the problem only occurred on my main box, not on my laptop.)

Sorry, I overlooked that you had fixed the problem. Verlegen

That works fine for me too until I reinstall the nvidia driver. Then I'm right back to where I started from with the kdm error message. Weird thing is when I run "init 5" the nvidia splash sreen comes up for a few seconds before returning to the console with the kdm error message. If I run "startx" from a terminal, I get the nvidia splash screen again and I am dumped back to the terminal with an error message about a "cursor" font missing and X refuses to start.
No problem with kdm or X if I use the nv driver however.

Thanks, dpkg-reconfigure solved my problem Sehr glücklich

Install-nvidia-debian.sh creates a fresh xorg.conf every time it is run (I think). I found that it did not work and restoring my original xorg.conf works. You should run dpkg-reconfigure again or restore the backed up xorg.conf.

You may be right stryder but that would indicate that something is wrong with the nvidia script. I thought they new xorg and the nvidia installer may have some incompatabilites, perhaps some links getting messed up between them. I'll try my luck at hand editing xorg.conf and see if I can get a fix.

I had what seems to be a similar font problem too, with nvidia, preventing X from starting. I had X font errors in /var/log/Xorg.0.log, including one or two specifying to try running mkfontdir commands. I recall I ran at least

mkfontdir /usr/share/fonts/X11/misc

to get X working again, also may have replaced the misc/fonts.alias file. I also used nvidia-xconfig to configure xorg.conf for the nvidia driver.
