thank you a lot for your post.

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 -q

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
