I have a nvidia video card and twin monitors. I tried using the nvidia_config and I had many problems especially after installing system updates. I have given up using the nvidia_congig tool.

In order to get into my system last time because it would not boot into graphics mode i had to delete xorg.conf in /etc/X11 which enabled my computer to boot as I would expect it to.

Although my first screen is detected correctly my 2nd monitor is not and I do not seem to be able to set it up. Can I edit a config file somewhere that will fix this problem.

I am using 2 identical monitors (AOC Intl 21inch) They both have a recommended resolution of 1920x1080 (16:9)

The output from xrandr is:

You could try reinstalling you nvidia drivers:

sudo apt-get purge nvidia*
sudo apt-get install nvidia

Reboot afterwards to activate the new drivers.

I hope this helps.
