I have a Nvidia card, I use the drivers from Nvidia, also have used 
Debians packaging of the same..prefer Nvidia's package.

I have a custom xorg.conf file that I used for years on my dual monitor 
setups.  Recently I moved the xorg.conf file aside and let Nvidia write 
a new one, works fine. 

If you are using Nvidai's driver I would start over and let Nvidia do 
its thing..see what happens.. you might be pleasantly suprised.
