I installed 256.53 and had the same problem. Then I followed the @Rho_T steps and changed grub, blacklist and the xorg.
But I didn't remove all my xorg.conf, only change the Device seccion adding Option "ConnectedMonitor" "DFP-0" but I didn't add Option "CustomEDID" "DFP-0:/etc/X11/nvidiaedid.bin" BusID "PCI:1:0:0" because I didn't know which PCI use and /etc/X11/nvidiaedid.bin was empty in my pc. When I restarted I have the related problem and my monitor shows a pretty black screen. Then I thought what I did and saw that haven't got any monitor named "DFP-0" and change this string to "Monitor0" (which is the only monitor I saw in xorg.conf), then start the kdm daemon and... chachan!
