Default Re: GeForce9600 + Linux = Problems (Resolution issue) | Can't make it higher than 640

Yes, as udippel mentioned, your monitor is returning invalid data to the graphics driver:
(WW) NVIDIA(GPU-0): The EDID read for display device DFP-0 is invalid: the
(WW) NVIDIA(GPU-0):     checksum for EDID version 1 extension is invalid.
You should contact your monitor vendor and report the problem to them.
