I'm trying to set up a spanning desktop on my Dell Latitude C640 laptop,
which has an ATI Radeon Mobility 7500 graphics chipset and a Dell 1504FP
LCD monitor in analog (VGA) mode. I use Gnome on Fedora 10.
I can (sometimes) get the spanning desktop to work using
System/Preferences/Hardware/Screen Resolution from the Gnome menu with
the laptop configured to be on the left, and the external display
configured to be on the right. However, this is actually the opposite of
my physical setup at my desk. Every time that I try to switch the
displays to their actual layout, the desktop still spans, but the
displays are mirrored, which is not only useless, but can also cause
problems, especially when sometimes it results in the display without
the top and bottom bars missing (!). Does anybody know how I can get
this work properly with the laptop on the right and the external monitor
on the left?
I would try to do it from the command line first, using xrandr. You can put all
desktops left, right, up, down of each other, overlap, rotate, reflect
sideways, upside-down, inside-out, and whatnot...
When you sort out the options that make it work as you wish, you can put it in
~/.login or /etc/rc.local or whereever...
man xrandr
Cool, I just ran xrandr --output VGA-0 --left-of LVDS and it worked!
So if I were to report a bug in the Gnome tool that seems to be screwing
this up, should I report it against the gnome-display-properties
application, and thus the control-center RPM? Or should I report it
against something at a lower level?
Thanks,
William
