The thoughts and musings of our team


I recently upgraded to Ubuntu 8.10, and everything works really well apart from the dual monitor support.

 My laptop has an NVidia graphics chip set. The laptop screen works well, but the attached second monitor was blank and did not show up in the display configuration applet (System > Preferences > Screen Resolution).

After installing the proprietary NVidia driver (required when I selected "Extra" level visual effects from the Appearance applet (System > Preferences > Appearance) the fix is relatively straight forward, a slight tweak to the /etc/X11/xorg.conf file, changing the the "Device" section to look like this:

Section "Device"
    Identifier  "Configured Video Device"
    Driver  "nvidia"
    Option  "NoLogo"    "True"

    ## JohnE added the following options for dual monitor support
    Option  "TwinView" "True"
    Option  "TwinViewOrientation" "RightOf"
    Option  "UseDisplayDevice" "CRT,DFP"
EndSection

Thanks.. worked a treat

Would be great if doing this were part of the GUI like in windows. Especially for doing thing like rotate.

Hi Paul,

glad it helped. I agree about the need for a GUI, the existing System > Preferences > Screen Resolution applet also failed to pick up the two monitors (and still doesn't even after applying this fix).

Hey man!... the code worked great!... although it did not get an accurate resolution in my HP L2245wg monitor!... it does display everything I do need,... and besides the fact that some adjustments to the nvidia x server display confg was required... everything came great1... THanks
