Ubuntu 10.04 Lucid Lynx: Dual Screen with nVidia GeForce MX 460 and nvidia-glx-96 legacy driver

Uprgrading to Lucid Lynx Alpha 2 somehow messed with my dual screen configuration, here is what you have to do to reconfigure it again:

1. Install the proprietary driver: sudo aptitude install nvidia-glx-96

2. Backup your xorg.conf file sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

3. Change your xorg.conf file to the following (sudo nano /etc/X11/xorg.conf):

Section “ServerLayout”
Identifier     “Layout0”
Screen      0  “Screen0”
InputDevice    “Keyboard0” “CoreKeyboard”
InputDevice    “Mouse0” “CorePointer”

You might need to play around a little with the options (such as the resolution). My advice is to use a second computer (preferably a laptop) and ssh into the first computer that you want to configure. That way you can comfortably comment out or add single lines to your xorg.conf even if you don’t have a visual picture.

If everything fails just revert back to the default xorg.conf with either one of the following commands:

sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

or

sudo dpkg –reconfigure -phigh xserver-xorg
