can't restart x with kdm

[Bruno Bigras]

Binary package hint: xorg

Both when starting the computer or after a logout, I'm unable to restart X using KDM.

When I try, the screen goes black then I see a login prompt. This happen 3 times and then nothing.

Hmm, it sounds like X either crashed or exited with an error, but none of the log files show what the error message might be.

Are you still seeing this problem with the released karmic? If so, could you attach your gdm log files (from /var/log/gdm/) ? Thanks!

Here's my kdm.log just after X failed to restart.

and here's a diff between before and after I tried to restart X.

Hrm, still is not showing a definite error message, but it seems to be going over into failsafe mode or at least trying. Perhaps there is something kubuntu-specific gone wrong.

You might try removing and reinstalling the nvidia driver, but sorry I'm not really sure what the problem here is.

Probably same as in #477066
