My hardware:

I just installed Ubuntu 12.04.2 LTS (Precise Pangolin) and I have been unable to get my dual 1920x1080 monitors working properly with my GeForce GTX 670 FTW.

The problem:

Whenever I get to the login screen both of my monitors display a purple back ground with small white dots and are mirroring each other (I can still see the mouse and move it).

In order to see the log in screen I have to unplug one of my monitors then plug it back in to the GPU, when I do this both monitors are now showing the login screen properly but are mirrored and stuck at a 1024x768 resolution and when I move my mouse to the right side of the screen the desktop slides over and disappears. When I move the mouse back over to the left of the screen the desktop slides back into place.

What I have tried:

I went into the display setting and tried to fix this but I am only given 1024x768 and 800x600 resolution options and when I unchecked mirror displays and click apply it defaults back to mirroring displays.

I believe this is a driver issue but I have no idea now to fix it ideas?

    I think what you need is a proper xorg.conf file. I have dual monitor setup and what you described happens to me whenever I boot mine without xorg.conf – Rey Leonard Amorato Jun 22 '14 at 10:12

Try (re)installing your Nvidia drivers:

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

I hope this helps.

  • I did that and got this it seems like it didn't install anything? james@james-Z68X-UD3H-B3:~$ sudo apt-get purge nvidia [sudo] password for james: Reading package lists...

  • Sorry I don't now how to do that terminal copy thing properly and this looks like a mess of text. – James Arreola Jul 11 '13 at 22:06
  • To paste in the terminal press ctrl+shift+v – Joren Jul 11 '13 at 22:08
  • Could you post you installed Nvidia packages here using dpkg --get-selections | grep nvidia so we can help you further? – Joren Jul 11 '13 at 22:10

    Also with sudo apt-get purge nvidia* you forgot the * (the most essential part). – Joren Jul 11 '13 at 22:12
