Comment 4 for bug 1017091

I've just tried the suggested workaround of adding "CLUTTER_PAINT=disable-clipped-redraws:disable-culling" to /etc/environment; it didn't fix even the sluggishness of moving windows around on Precise's fglrx, left alone multimonitor not working, black screenshots and screencasts, etc.
Quantal's fglrx 9.x is no better - it's completely broken on my HD 6770.
I guess we'd better give fglrx a GTFO after all. r600g is official and, as opposed to fglrx, it *works*.
