I have a laptop whose widescreen LVDS reports these modelines
(correctly, afaik):

When I plug in the VGA, X chooses the highest common resolution, which
happens to be 1024x768. I can only ponder as to why a 22" VGA monitor
does not want to do 1280x800, but that's not the question. What I
would like to have is the following setup:
* when VGA is not plugged in, LVDS should be up with its native
resolution (1280x800)
* when VGA is plugged in, LVDS should be off, while VGA in its native
resolution (1680x1050)
It would be nice to have this hot-pluggable, but I don't mind
restarting X or the computer for the change. Can anybody tell me how
to configure xorg.conf to make this happen?
My current xorg.conf is fairly simple so far:
########################
Section "ServerLayout"
Identifier "X.org Configured"
Screen "Screen0"
EndSection
Section "Device"
Option "AccelMethod" "XAA"
Identifier "Card0"
Driver "intel"
VendorName "Intel Corporation"
BoardName "Mobile GM965/GL960 Integrated Graphics Controller"
BusID "PCI:0:2:0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
EndSection
########################
The AccelMethod is set to XAA because of that famous intel random
lockup thing (it doesn't eliminate the bug, just makes it more rare),
everything else is autoconfigured.
Thanks, :-)
