Re: Video card that will support 2560x1440 under Ubuntu
I don't think it's possible with any adapters avaliable on market.
You probably won't get 2560x1440 by D-SUB, but not by DVI.
P.S. Ofcourse you won't get 2560x1440 framebuffer without using nouveau drivers, but I don't think it's a big problem, cause in X you should get full resolution any way.
