Dual Monitor help

[toddbmobile]

I have a hp desktop I just installed 9.10 on. I am using the restricted video driver 185 for Nvidia. The Nvidia utility will config and set up both monitors (Acer flat, 20' Dell CRT) like I want(Left of, Right of, etc), and even let me appy the changes. The bad new is when I click the save to xconf file it wont save and gives me an error message. So when I reboot, I am back to only one monitor and I have to start the process all over again. How can I get the settings to stay?

Hi

Your xorg is write protected...that's the reason why you can't save the changes, i had also that problem, i solved it by changing the security properties of the xorg.conf, using the sudo nautilus code in the console and navigating to is location etc\X11. I think you can also launch Nvidia control panel in sudo mode, by typing sudo nvidia-settings, and maybe (not sure) in sudo mode it allows you to save changes to xorg.

See ya

Best way to do it is to run nvidia-settings as root.

Easiest way to do this is to just press alt+f2 and in the box that appears type 'gksudo nvidia-settings' and hit enter.

Thanks for the advise but I still can't get either suggestion to take. I changed owner to myself w/ read and write permissions for xconf file. When I save to it I get a window that pops up the message "Failed to parse existing xconfig file" and the path etc/x11. In the terminal window I get

VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Undefined Device "(null)" referenced by Screen "Default Screen"

any other ideas? Please help....thank you in advance.

I found the solution from johnnydopefish's website.

Below is the solution that worked:

The NVIDIA applet in Ubuntu 9.04 (works w/ 9.10 as well) will not write to the stock xorg.conf regardless of permissions set, and regardless of whether or not it's running as root.

Here's what I did to get around it:

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
sudo nvidia-xconfig
sudo nvidia-settings

The first step creates a backup of your currently working xorg.conf file.
Step 2 runs the NVIDIA utility to generate a new xorg.conf file that the utility can actually read.
Step 3 runs the graphical NVIDIA setup tool as root, so you can actually save your changes.

If this does not work then after step 1, do sudo rm /etc/X11/xorg.conf to delete your current xorg.conf file. Then run sudo nvidia-xconfig and sudo nvidia-settings.

I hope this helps someone else.....

Thanks Todd! This fixed my prob. Even if I ran it as root I couldn't get it to save to the settings. I had followed a walkthrough on another post, but I think doing the "sudo nvidia-xconfig" is what worked for me! Thanks!
