I have problems with alt+tab. When I use it the bars where are
(close,minimize and maximize) disappear. And compiz is not even
installed. I installed it and try to make some changes but it almost
always crashes and I can't even reboot with terminal. System freezes. I
thing maybe is something to do with VGA drivers, because when I
installed 12.10 when I move windows they appear to lag like I have low
fps. My VGA is nvidia 450GTS and now I am with 295 .20 drivers which I
install from app "additional drivers".
