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].

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.
