Re: Linux drivers for 30" Dell or Apple monitors?
Yes, all those cards are supported by the Nvidia Linux drivers. The drivers are available on Nvidias homepage, and linked from this very forum (the sticky posts at the top). And I'm quite sure 30" monitors should work just fine, all you'll probably need to do is configure X11 correctly (size, hsync, refresh, resolution - or worst case: a modeline). I use an even more exotic display, and it works perfectly out of the box (sgi 1600SW).
