X11 won't start

[cliff here]

I'm having an issue when I try to login to XServer; on my KDE desktop if I
try and provide my credentials it spits me back out to the login prompt,
//var/log/messages says:

Localhost pam: gdm-password[1888]: pam_unix(gdm-password: session: session
opened for user by (uid=0)

So i know that the authencation isn't failing because I can login to run
level 3 just fine, it's the gui that flickers restarts. I've checked the
xorg logs and there doesn't seem to be anything unusal in them.
