Comment 1 for bug 196680

Update:

As the errors were relating to width and height, I thaught maybe my multi-screen setup was causing it (nvidia card)
so I have backed up /etc/X11/xorg.conf and generated a new one with nvidia-xconfig.

I then ran 'gdm' from a terminal as root. Login prompt appeared in one screen, with the other monitor still off.

Still no luck, hangs in exactly the same place

(If it's of any use, monitor is 1440x900 19" wide screen)

I will include my current xorg.conf with this post
