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

with one comment

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”
EndSection

Section “Files”
EndSection

Section “InputDevice”
# generated from default
Identifier     “Mouse0”
Driver         “mouse”
Option         “Protocol” “auto”
Option         “Device” “/dev/psaux”
Option         “Emulate3Buttons” “no”
Option         “ZAxisMapping” “4 5”
EndSection

Section “InputDevice”
# generated from default
Identifier     “Keyboard0”
Driver         “kbd”
EndSection

Section “Monitor”
Identifier     “Monitor0”
VendorName     “Unknown”
ModelName      “Unknown”
Option         “Twinview” “True”
Option         “TwinviewOrientation” “RightOf”
Option         “UseEdidFreqs” “True”
HorizSync       30.0 – 110.0
#    VertRefresh     50.0 – 150.0
VertRefresh     60.0
Option         “DPMS”
EndSection

Section “Device”
Identifier     “nVidia Corporation NV17 [GeForce4 MX 460]”
Driver         “nvidia”
VendorName     “NVIDIA Corporation”
EndSection

Section “Screen”
Identifier     “Screen0”
Device         “Device0”
Monitor        “Monitor0”
DefaultDepth    24
SubSection     “Display”
Depth       24
Modes      “1280×1024” “1024×768”
EndSubSection
EndSection

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
