Unable to login to KDE from KDM

Chrysalid · 08-10-2006, 03:23 AM

Hi, I'm having a weird problem with the KDE login manager. When I boot up, the login manager window comes up, I enter my password and press Login, but the screen goes blank, as if it was trying to switch video modes, and then it goes back to the login screen. I have typed the password correctly, so that's not the problem. I can get KDE up by starting the x-server manually and then running startkde. Can anyone suggest what could be wrong?

"dpkg-reconfigure kdm" didn't help, "apt-get --reinstall install kdm" didn't help.

I have downloaded KDE 3.4 packages from the Debian Unofficial repository.
I have the stock kernel 2.6.8-2-k7 and I'm using the XFree86 version seen on the logfile (4.3.0.1)

/var/log/kdm.log:

I ran into symptoms that looked exactly like that on a recent Debian install. It turned out that I was out of space in the OS partition. Thus, what was happening was that KDE couldn't start and upon failure the X server restarted (bringing up kdm).

The system wasn't completely crippled, because the default ext3 file system reserves 5% of the space for the root user. Thus, it's possible to log in as root and do some cleaning up.

If you log in to a text console, what do you see when you enter "df"?

One thing you can do to quickly reclaim a lot of space is run "apt-get clean" (as root). This removes cached .deb files.
