Hi, My XFree86Config file finally got tweaked and it works fine with my NVIDIA card - [still no 3D but it works at least]. The method for determination of modes is "IteratePrecisely" and I have not had to specify modelines. Now there is only one place to specify the resolutions, and I did. The first resolution is taken fine. The second resolution is not switchable with control-alt-[+/-]. I remember something like a virtual resolution, or some other keyword which we used to have with X3.x where the switching of resolutions was possible. That is not yet present here. Would someone send me some insight on this?
