I have a first gen MacPro, a hand-me-down from my dad. The video card is on it's last legs. It's the original card (ATI Radeon X1900 XT) though for a couple of years it had an NVidia 8800. I put the old one back in when the 8800 died. Good thing dad kept the old one when he put in the 8800. Anyway, I'm trying to make heads or tails of the whole video card issue. If I can't find a way to keep the Mac Pro running, I'm going to be stuck using my husband's computer, or my dad's long unused Mac laptop. From the sound of things, finding a compatible video card is not just about hardware, but the OS, right? What I'm wondering is, can I find a cheaper alternative if I switch from OSX to Ubuntu? $150< is really out of my price range. My thought is to find an acceptable, and affordable, video card for every day use, and keep the X1900 is reserve for when I need to do firmware updates. I have a hard drive that I'm already running Ubuntu 10.04 on. In order to boot that, I have to do the whole, hold the option key and select the drive thing. I never see the white Apple screen when I do that. When I select the Ubuntu drive, this in turn takes me to your standard black and white GRUB screen, where I then select the Ubuntu OS. (incidentally, I can also load the Mac OSX from the GRUB, though it loads with a standard black and white screen, like a PC would.) Starting up in this manner, am I bypassing the part that the Mac would normally get hung up on, when loading OSX? Is this plan feasible?
