I use Ubuntu 11.10 for my desktop, but that said, I run an ATI 5770 card 
in triple head mode with full acceleration (and compiz, mainly to make 
Docky happy). All three run DVI with two coming from the built-in DVI 
ports and the third coming from an active DisplayPort -> DVI adapter. It 
took a bit of fiddling around with the Catalyst control panel to get 
working right, but the only really persistent problem I've had is that 
when you first log in the DisplayPort -> DVI doesn't always come up 
immediately. It can take a few minutes to decide to come on. Once it 
finally comes up it is fine.
