I had to install under safe graphics mode to get it to run with my ATI card. Then after updates I could install correct drivers. A small inconvenience. I installed the 64 bit version on an AMD +2 5500 black edition. Four gig of mem and a 250 gig sata. The only problem was the updates with those three files that hang. The "libcairo2" "mplayer" and "pidgin-libnotify" After reading here in some forums, I discovered I was not the only one with that problem. I had to install VLC Player which is much better than mplayer any way. I am happy with it and will encourage others to use it.
Bjjl.
