Managed to get dual screen working on a Dell Latitude D600 laptop with a Radeon Mobility 9000 M9 in combination with a 2001FP 20inch TFT screen.
My requirements:
1) At the office, I want to use dual screen with the menu bar on the external screen.
2) Outside the office, I only want (can) use the laptop screen, of course with the menu bar visible.
3) When booting, I want to be able to log on using a visible logon textfield
4) When I plug out my laptop, I want to switch from dual to single screen very easily
What I did:
This is the xorg.conf file I use:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

This setup makes my laptop boot very weird, I can see half of the screen. However, I can logon. Then I see a screen without the menu bar, so I have a problem. I solved this with creating a launcher file (right click on the desktop, create launcher) with this command
xrandr -s 0
This command changes my screen settings to the first meta mode with a single screen. When I run
xrandr -s2
I get a nice dual screen set up. When booting with the external screen connected, everything is fine. It’s even possible to use System/Preferences/Screen Resolution and do it the GUI way.
Does this make me happy?
Well, it’s not perfect yet, but it works for me. Actually this is one of the issues I had to solve before switching from Windows to Ubuntu on the business desktop – my boss did not invest in a huge screen without expecting me to use it.
Maybe someone can tell me how I can make my laptop autodetect if there is one or two screens?

Follow this. Worked for me.

Address autocompletion in Evolution did not work fine for me and I changed some settings. That was a bad idea, as I was not able to reply to email anymore. It happened that I set the automatic contact feature to Global Address List, which in my case is LDAP and unwritable to me. This caused a time out – Evolution wanted to add the email address to the address book which was unwritable – and Evolution hanged. Changed the automatic contact source to something else and now it works like a charm again.
