restricted nvidia driver

[swappo1]

Hello,

I am trying to set up the restricted nvidia driver from the live cd so I can set my monitor to 1920x1080 and 60hz. When I run nvidia-xconfig as root, I get the following message:
root@ubuntu:/home/ubuntu# nvidia-xconfig

Using X configuration file: "/etc/X11/xorg.conf".

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

Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'
How do I change the settings in nvidia x server settings? Can I do this manually? Here is xorg.conf:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig

Hi,

Have you had a read through of the sticky at the top of the page on ATI and nVidia drivers ?
http://ubuntuforums.org/showthread.php?t=1305459
It covers quite a lot of potential issues.

A set of threads related to nVidia is here --> http://ubuntuforums.org/tags.php?tag=nvidia

Regards,

Phill.

Hi, thanks for the response. I checked out those threads. All the solutions require a reboot. I am running from a live cd and can't reboot. I installed the glx1.85 driver from synaptic and run nvidia-xconfig as root. I get the following error:
root@ubuntu:/home/ubuntu# nvidia-xconfig

Using X configuration file: "/etc/X11/xorg.conf".

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

Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'
I don't have access to Nvidia X Server Settings to change the resolution.

I think You'd have to re-master your LiveCD
There are tricks on how you can get to feel the GNOME system in your chroot environment.
1. Copy your xorg.conf in the chrooted "etc/X11/" directory.

cp /etc/X11/xorg.conf edit/etc/X11/2. Create generic devices on your chroot system using MAKEDEV

cd /dev/
MAKEDEV generic3. Start X or restart gdm

/etc/init.d/gdm startSupposed you want to make modifications on the Desktop, that will be used by all the new users, just change your $HOME to /etc/skel/ and start gdm or X.

export HOME=/etc/skel/If you want to load all the other stuff GNOME needs (i.e, dbus, avahi, network-manager), just boot as (single-user mode), and start dbus in your chrooted environment.

/etc/init.d/dbus startAn example of the whole procedure. (under single-user mode)

sudo /etc/init.d/networking restart
sudo cp /etc/resolv.conf edit/etc/
sudo cp /etc/X11/xorg.conf edit/etc/X11/
sudo chroot edit
mount -o none /proc
mount -o none /sys
export HOME=/etc/skel/
cd /dev/
MAKEDEV generic
/etc/init.d/dbus start
/etc/init.d/gdm startbut that's beyond me !!!

https://help.ubuntu.com/community/LiveCDCustomization

Has all the info on doing that sort of stuff !!

You may be able to restart X and get it to read your revised file, but, again - that's beyond my knowledge.

hopefully someone can come up with a different solution for you.

Phill.
