This might be related to https://bugs.freedesktop.org/show_bug.cgi?id=93629 but a few things are different. The screen freezes except for that the mouse pointer can be used (click has no effect). Apart from the magic syskeys (sync, unmount, boot) the keyboard doesn't react. I can not use ALT-tab to switch to another program. I can not leave the game (fullscreen mode) by using the ingame console or using ALT-F4. The mouse pointer is trapped on the monitor where the game runs (I have two). The sound keeps playing and sound effects are played now and then too. I tried to get to the terminals via CTRL-ALT-F[1-6] but nothing happens. Switching (KDE) desktops via CTRL-ALT-[arrow-left,arrow-right] is just the same. So far the problem happed when I used app-emulation/wine to play a game (namely MassEffect 2, I haven't tried others) and once when I used firefoy (maybe when using youtube). It happens unexpectedly, at least I didn't find a pattern. I downgraded to xf86-video-nouveau-1.0.12 - seems like it happens less often. Once when using firefox (probably watching a video).

On one occasion I was able to kill xorg (?). The effect was that the session was over but I could log in and start working - no reboot! Can you try using ALT+print+k ? It took quite a while until the login screen was available, maybe five minutes. Anyhow that works *sometimes* and often it does not.
