I just freshly installed Ubuntu 14.04 and did only 4 things:

1)

$ sudo add-apt-repository ppa:xorg-edgers/ppa $ sudo apt-get update $ sudo apt-get install nvidia-340

2)

sudo apt-get install nvidia-current-updates nvidia-settings-updates

3) Went to Software & Updates/Additional drivers and chosen

Using NVIDIA binary driver - version 340.32 from nvidia-340 (open source)

I had to do part 3 because after part 1 I had driver version 304

Now to the main part. I cant set up custom resolution. When I had Ubuntu 12.04 year ago there was option in Nvidia x server setting called "Add custom resolution" or something like that and it was alright. Now this option is gone. How can I change/add custom resolution?
