screen resolution reset after reboot

[Grenage]

I had the same problem on one machine, manually emptying the file worked for me:

#backup the old config:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.backup

#create a new blank file:
sudo touch /etc/X11/xorg.conf

#Run Nvidia settings, make changes and save:
sudo nvidia-settings

For newest NVIDIA driver (271) this post http://ubuntuforums.org/showpost.php...52&postcount=2 fixed it for me, saving or changing xorg.conf didn't work. Alternatively you can put xrandr -s 1920x1080 in startup script if above doesn't work
