I'm using Ubuntu 8.04 with an Nvidia 6800GT graphics card. I've installed the restricted drivers for Nvidia and adjusted the resolution to the maximum available for my monitor (1920*1200) using Nvidia X Server Settings.

When I go to "Save to X Configuration File", I get the following error:

"Unable to remove old X config backup file '/etc/X11/xorg.conf.backup'"

The resolution does change to 1920*1200 but after shutting down and restarting my computer, the resolution defaults back to 1680*1050. I can change it but I don't know how to save the settings for 1920*1200.

Is there some options/commands to save the new settings?

I would guess you can't remove it because you don't have root privleges to write in the /etc/X11 without typing in your password first. Before running the command prefix it with sudo (or if you are doing it from a graphical environment gksudo)

Hi and as jamesrl pointed out
gksu nvidia-settings

What is the command I would use? I had been adjusting the resolution and trying to save it using the GUI options available.

So close the current Nvidia-settings if it is open, then type in Alt-F2 (to run an Application) and type in

gksu nvidia-settings
reconfigure it to your settings and it should now be able to save the configs in the directory /etc/X11/
