I have been dealing with this for a while now. I have the latest drivers installed on my system (64-bit Linux Mint 13 Maya with MATE) and there is no 1600x900 resolution option for the display.
When I was using my on-board graphics card, I had found a work-around online by using xrandr. Now that I am using a GeForce for my display the xrandr trick isn’t working.
On another forum it was mentioned that the NVIDIA driver does not allow xrandr to alter the resolution, is this true?
I also have tried generating a xorg.conf from the NVIDIA x-windows control panel but this doesn’t work either.
Any ideas on how to add a 1600x900 resolution option?
This seems like such a simple thing but has been causing people so much frustration.
