Nor is it possible to switch between internal and external screen with the magic Fn+F7 key-combination.

A small work work-around bash-script, that utilizes Zenity, which I grabbed from here (following a tip from Joar), eases the pain. I have modified it slightly, and here it is: 

 1     #!/bin/sh
 2 
 3     ans=$(zenity  --list  --title=" Screen configuration" \
 4     --text "Select desired screen configuration:" \
 5     --radiolist  --column "Pick" \
 6     --column "Output Type" TRUE LCD FALSE VGA \
 7      FALSE Both);
 8 
 9     echo $ans
10 
11     if [ "$ans" = "LCD" ]
12     then
13             echo "LCD"
14             xrandr --output VGA --off
15             xrandr --output LVDS --auto
16     elif [ "$ans" = "VGA" ]
17     then
18             echo "VGA"
19             xrandr --output LVDS --off
20             xrandr --output VGA --auto
21     elif [ "$ans" = "Both" ]
22     then
23             echo "Both"
24             xrandr --output VGA --mode 1024x768
25             xrandr --output LVDS --auto
26     fi

Adjust the mode parameter in the "Both"-case to match your screen size.
