If you use dual-screens, Ubuntu Ibex, and the Nvidia drivers, you were probably just as mad as I was when you configured your dual-screen setup, clicked the handy “Save to X Configuration” button, and saw your nvidia-settings window disappear.
Ya, its a bug. Luckily, it is easy to fix. Apparently nvidia-settings doesn’t like overwritting the default Xorg file. In order to make it happy, open a new terminal and type:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
sudo /usr/bin/nvidia-settings
Set up your dual-screen settings, click the “Apply” button, and then click the “Save to X Configuration” button. You’ll be prompted to enter a path. Enter this:
/etc/X11/xorg.conf
And press “Save.”
Restart your computer/Xorg to make sure it worked. If something went wrong, restore the xorg.conf_backup file to its previous glory and try again.
