Can't login anymore

view full story

http://forums.opensuse.org – I was working normally and the GUI just failed, all I could still see were any open windows. I rebooted the machine from tty1 and now I can't login anymore under my normal user accounts. I enter my credentials, it appears to login, and immediately goes back to the login screen. Note that under tty1 I can still login with my user account and do everything. I can still login with root in the gui. /var/log/messages says this Code: machine checkproc: checkproc: can not get session id for process 9839! I really have no idea what's going on or how to fix it, please advise. (Distributions)
