triple head state of the art
currently, i run dual head using nvidia twinview, or amd catalyst. this works fine (nvidia performance is > amd) for everything i use, including compositing.
but there are a few issues...
- rotated display hurts performance
- triple head using xinerama breaks compositing
- unsuccessful using both nvidia and amd video cards in one machine
so... i am considering move to triple head or one really big monitor to avoid the headache...
thing is, eyefinity could save the day. but does it work with linux? and compositing?
Unfortunately i don't have any clear answers... I do want to follow this thread though...
One point of clarification -
Do you mean two video cards with three active heads? Or one video card with 3 heads?

I think that AMD/ATI Eyefinity will do the triple head (+ rotation & compositing) job... eventually. So far, it does not appear to fully supported yet.
