Hello, Just an idea of mine, but if this issue only happens after logging in (to gnome-shell?), perhaps you could try installing+logging into the xfce4-desktop? Just to see if that still triggers the nouveau bug. And then if xfce4 is stable, you could perhaps try `mplayer -vo xv somefile.avi` to see if that will trigger the problem instead. Thanks!
