How to switch to a particular resolution? Xorg complains "No valid modes for "DFP-1:2560x1600"; removing." and ignores my setting.

Interestingly, this command shows nothing after Xorg was started, but 
shows 2560x1600 after the "NVidia settings" program changes the 
resolution to 2560x1600.

I just need to find a way, if any, to do this automatically.
