Install xbindkeys:
sudo apt-get install xbindkeys xbindkeys-config
Get this python script:
* {{:howtos:aticonfig_switch.py|aticonfig_switch.py}}
and place it e.g. in ~/bin
Make it executable:
chmod +x aticonfig_switch.py
Now run:
xbindkeys-config
and bind the script to a key kombination. I use //Winkey+S//.
The next time you resume after having docked or resuming in the dock you just wait to the login dialog comes up (the one you cannot see :-P), type in the password and press the key kombination. You should now get the screen to your monitor after a couple of seconds.
