This might be related to https://bugs.freedesktop.org/show_bug.c=
gi?id=3D93629 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 sou=
nd
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 (na=
mely
MassEffect 2, I haven't tried others) and once when I used firefoy (maybe w=
hen
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 ofte=
n.
Once when using firefox (probably watching a video).
