Login screen wont appear

[Guest]

I upgraded my installation to the latest version of Kubuntu 9.1 a few days ago. Whenever I load it now, the login screen appears for a split second, then disappears and the KDE loading screen appears and freezes after a few seconds. I'm not entirely sure why this is happening, I have not changed any configuration since I upgraded, and it never happened before then. Just curious to know if anyone has any suggestions on how to fix this.

I've had this happen a couple times too, don't know what caused it.

I usually ctrl-alt-F1 to tty1 and log into a terminal and then do a

killall kdm

and kde resets to the login screen almost immediately.

I don't remember if I had to use sudo or not.

It seems to me that something pushes kde to start loading without prompting for the login, but then it needs the login, and can't get back there on its own.

Boot into recovery (Single User) mode. At the command line, type:

df -ht

If your Use% is (or very close to) 100% for your root ( / ) partition, you need to clean up your system. Type:

apt-get remove && apt-get clean && apt-get autoclean

Then,

df -ht

If your Use% on your root ( / ) partition is below 98% you should be able to login normally.
