the switch to linux

so IVe been wanting to make the switch over to linux … but ive ran into a snag and its call ATi video cards are not 100% supported even with the open source driver provided from ATi themselves … the problem im running into and maybe someone can help me but when i install or enable the ATi drivers i cant boot into ubuntu it just goes to a blank screen and i have to reboot into recovery mode and tell it to use the native driver thats installed with ubuntu by default ..

I’m sporting an Ati x1650 pro card.

that’s the one major problem the other problem im having and maybe its just a matter for just breaking down and getting a vmware type program for linux to run this, but being able to use CS3 for work and my artwork i do.  Gimp just cant do what i need it to do.
