UPDATE!!
Ok so the cube thing works and stuff but it is kind of silly.
I have 6 monitors on 3 gfx cards on my comp but Ubuntu didn't recognize them. It only sees the first one. I want to use all my screens.
I tried messing with the xorg.conf file to get all the screens entered in there but I can't get it to work. I was reading online and someone said to install SUSE, which generates the conf automatically, and then copy that to Ubuntu. So I was like, ok why not just use SUSE then?
So I tried to install SUSE (Internet Install version) and it couldn't download some files (????!!!
) so it doesn't work. I'm trying the DVD version tonight.
