This happened to me before and I'm using an Intel GPU. It's rare though; I haven't seen it with the new GNOME 3.16. I hope you have a SysRq key for proper rebooting [1].
Finally, in Arch Linux I've become used to have X server started over tty1 and tty from 2 to 7 free. Actually, when startup reaches the end without faults, it start X server on tty1 then GDM (Gnome Display Manager) is shown on tty1 but once I log in to my account, my desktop is shown on tty2 and tty1 keeps displaying GDM.
I'm quite puzzled by this and I don't know whether the last symptom is a bug or a feature (maybe multiple user simultaneous outputs). I've also enclosed for your information my [Xorg.0.log] file and [lsmod] output. If it's a bug, which software should I fill a bug report to? nouveau driver, X, GDM, Gnome?
I don't think this is a bug. It happens for me too and I like it because I can log in with multiple users and easily and rapidly switch between them. I don't know if the proprietary Nvidia driver is better than Nouveau for GNOME usage. It has less features, even though rendering is faster. I don't have problems with it, but I don't remember problems back then when I used Nouveau either. [1] https://wiki.archlinux.org/index.php/Keyboard_shortcuts#Kernel
