Nvidia and multihead

[Robin Haswell]

Hey guys

I noticed there were some discussions about multihead on here recently 
(the /. one), so I though I'd add my $0.02 to this. My work recently 
lavished second monitors on us all, and in the office I use a 
bastardised XFCE front-end / GNOME services & sessions / e17 relics 
hybrid. Anyway xfwm4 is my window manager. What all this boils down to 
is, xfwm4 kicks ass with either Xinerama or Twinview, there's no 
usability difference between the two whatsoever. However, painting is 
glacially slow with Xinerama, and judging from Xorg's CPU usage I'd say 
Xinerama nukes the hardware acceleration, but with Twinview everything's 
nice and zippy so I'm happy.

Dunno if this post means anything to anyone but hopefully it might one 
day help someone.
