Been trying to get another os besides OS X on my Quad but no matter what I try it doesn't seem to work. I get a massive graphical error after install. Have tried Debian 8.7.1 as well as Fedora Server. Both once installed show the attached image. Having thought it was my quadro I swapped back in the GeForce 6600 back but same result. Oddly enough the artifacting has some of my leopard install background (and that ssd isn't connected). Any help would be appreciated.
