Suse Linux 9.0 can't login
I need some help here. I have a Suse Linux here that I can't login to. I used to be able to, but now I can't. I was able to login initially, not too sure what keyboard button I pressed(Alt+Tab, maybe), then it kicks straight to the login screen. Subsequent login as root didn't manage to get into the desktop. Login is successful though(no login fail error message), just that the login screen kicks straight back out.
Tried to restart, but to no avail. Saw this Restart X-Server, what's that actually?
Do appreciate any help given. Thanks.
