Xorg.0.log

At boot, GDM fails to start on VT0. If, after the boot is completed, and the
login prompt appears, I switch to VT1 (by pressing Alt-F2), GDM starts.
I'm using the proprietary Nvidia driver (nvidia-glG06-515.65.01-lp154.15.1).

/var/log/Xorg.0.log contains a crash (I've attached the entire log):
