Hi Mark, the graphics card i'm using is the ATI Rage it's an old one from early year 2000 and i've used it successfully with ubuntu from 7.04 up to 8.04, but it doesn't seem to like EMC2 so I may have to think about replacing it. I think the main difference is EMC2 is working in real time. If it was too easy it wouldn't be so much fun.;-) Cheers John Dunn
