Thanks. I agree and now that I think about it, I can always get the older nvidia-driver from somewhere. > On Fri, Jul 27, 2012 at 4:10 PM, Allan Gottlieb <gottl...@nyu.edu> wrote: >> I am getting a new laptop.

I forgot a big point. I have a very high res 30" monitor (2560x1600) and need to insure that the graphics card can drive the monitor at full res (I don't care about dvd's just software development and writing my lectures). I haven't received a definitive answer from dell about that. I am really in a quandary over the graphics card. The nvidia card is a little new and not listed on the nouveau page (I have found nouveau works much better than nvidia-drivers). Also it requires a bigger battery and power adapter. Indeed with the intel 4000, I could get a physically smaller dell 6430s with the same 14" screen (but somewhat lower res). allan
