Hi everyone.

Is there anyone using xfce 4.6 in a notebook, one card with internal LCD and
a external VGA connector or whatelse external connector, who had got desktop
and display programs in settings menu to work fine ? My desktop program only
shows me just one monitor and display shows me just one screen.

My intention is have two screens where a maximized program fits just in one
monitor and the xfce panel appears in just one monitor too. There is another
requisit, sometimes my VGA is plugged, sometimes not.

I don't have xinerama use flag enabled and have no intention to use it. I
had read a lot of dualhead configuration at gentoo wiki and other sites, but
they didn't work for me.
If you are a luck guy with a notebook as I described, please share your
xorg.conf and xrand comands with me.

Here is my xorg.conf :

My xranrd output :
#xrandr -q

TMDS-1 disconnected (normal left inverted right x axis y axis)

Nowadays I'm  using this command to active the VGA monitor, but the result
is a big screen with a lot of programs doesn't work well.

xrandr --output LVDS --mode 1280x800
xrandr --output VGA --mode 1024x768 --above LVDS

and this to deactive VGA

xrandr --output LVDS --mode 1280x800
xrandr --output VGA --mode 1024x768 --same-as LVDS
