I get the following error:

Cannot start session due to some internal error.

then i click on ok, i get the following error:

your session lasted less then 10 seconds, this could be due to not enough diskspace or some other problems look to .xsession-errors file.. ..but i do not htink that sounds right.

If i see the additional error on the screen, i get
/etc/PreSession/Default: Registering your session with wtmp and utmp
/etc/PreSession/Default : running /usr/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x
session_child_run: Could not execute /etc/gdm/Xsession default






the .xsession-errors file says alot of things..but the first entries are :

Xsession: X session started for root at Mon Feb 25 13:34:37 EST 2008
SESSION_MANAGER=local/rmachine:/tmp/.ICE-unix/6807
