Re: Getting dual monitors to work on Gnome 2.26.1

[Puvi Ganeshar <puvismail gmail com>]

Thanks very much for your help.


I have managed to resolve this by running sudo
gnome-display-properties on the command prompt and un-checking the
"Mirror screens" check box and clicking "Apply" button.


So why did this not work via System -> Preferences -> Display
?  Could it a permission problem as on the command prompt, I ran it
with sudo.

This is not a issue with gnome, but rather with Xorg. Update
"/etc/X11/xorg.conf" file to reflect as shown below

Section "Screen"
       Identifier "Screen0"
       Device     "Card0"
       Monitor    "Monitor0"
       SubSection "Display"
               Viewport   0 0
               Depth     24
               Virtual   3200 1500
       EndSubSection
EndSection

Try sending in a talking to your distribution
"list" ( fedora-list/ubuntu forums/... ) .
