X restarts when attempting graphical login for users other than root.

[cantab]

Recently X is restarting when I try to login as a user other than root. This occurs regardless of session type (I have both kde and xfce). Console logins work, as do root logins (I changed /etc/kdmrc to allow them), though for some reason no window decorations appear in kde, though they do in xfce.

I've been fiddling around with users a bit recently, since I wanted to change my username. So the issue's likely some kind of file ownership or permissions problem.

I don't know if this is related to my other problem, see other thread.

OK I've traced the issue; my home partition is messed up.
