thank you a lot foir your post.

In tried it.

I copied from your xorg.conf
that part and tried the command. 

It didn't work.

After the command

"xrandr --output LVDS --mode 1024x768 --output VGA-0 --mode 1024x768 --left-of LVDS"

it created on the laptop screen on the right a blue area...

Maybe the screen are completely messed out.
The laptop screen is replaced by the external monitor?

When the system enters into gdm the external
screen is going out already.

I think that I made the upgrade into 'lenny'
when the external screen was connected.
Maybe that created a problem?

I spent quite a long time already yesterday
with that wiki text. But it didn't help much.

Where should you put that

"xrandr --output LVDS --mode 1024x768 --output VGA-0 --mode 1024x768 --left-of LVDS"


In "xorg.conf file" or?

the output of xrandr -q in my system:

xrandr does work on Lenny. We've got two laptops using it with no problems. Studying http://www.thinkwiki.org/wiki/Xorg_RandR_1.2 was really helpful, particularly understanding the 2048x2048 concept in the Virtual screen section.  With xrandr you keep your xorg.conf file to a minimum.

Obviously your mileage may vary but if it's any help, my xrandr command is:

$ xrandr --output LVDS --mode 1024x768 --output VGA-0 --mode 1024x768 --left-of LVDS.

I had to change VGA to VGA-0. You can find your own display types with:

$ xrandr -q

That's it, although in Xfce I have to log out and then back in again to get the extra widths showing in the desktop workspaces.

Hope it helps


Here's an extract from my xorg.conf:

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
#       DefaultDepth    24
  SubSection "Display"
#       Depth           24
#       Modes           "1024x768"
        Virtual         2048 2048

Then, from the command line, run:

xrandr --output LVDS --mode 1024x768 --output VGA-0 --mode 1024x768 --left-of LVDS


A quick check - did you restart X after changing xorg.conf ?
Can you bottom-post to keep it readable ;)

Can you post the relevant parts of your original xorg.conf?
