Well, the first problem is a nasty one : All nVidia driver version  
newer then somewhere in the middle of the 8xxx series require  
resolutions to be a multiple of 8.  Which really sucks, as me, you  
and anyone else with a Plasma have a physical resolution that is not   
divisible by 8.  So, since the older nvidia module that worked is no  
longer on atrpms, I'm stuck at 1024x720 for now (which my panel also  
overscans horribly).

When I'm trouble shooting x server, I generally break out of the  
login screen to a text login and run :
startx -- -logverbose 6

You'll probably see all sorts of errors about physical size maximums,  
horizontal freq problems and EDID failures.  I wish nVidia would fix  
the current crappy line of drivers.

Here's some various options that may or may not help :
#       Option      "UseEDID" "FALSE"
#       Option      "ModeValidation"  
"NoDFPNativeResolutionCheck,NoHorizSyncCheck,NoMaxSizeCheck"
#       Option      "ExactModeTimingsDVI" "true"

On mode validation, only add the bare minimum of options to get past  
the errors you get in your log.

Good luck!
