I decided to move my 21″ monitor from my desktop computer to my laptop that runs Ubuntu. Since I have a DVI interface on my monitor and a HDMI interface on my laptop I had to buy a adapter. I bought one at Clas Olson and it worked perfectly.
Ok, now I had to switch my primary monitor so my external monitor holds the panels instead of the built in monitor that is the default monitor. After a quick google I found this perfect blog post that describes the problem and has a nice solution. Kudos to you Andrew.

xrandr –prop | grep “[^dis]connected” | cut –delimiter=" " -f1 # query connected monitors
read choice # read the users’s choice of monitor
xrandr –output $choice –primary # set the primary monitor
Save it with the name monitor-switcher.sh. Make the script executable with ‘chmod +x monitor-switcher.sh. Now it’s time to run the script.
Enter the primary display from the following:
As you can see I choose the DFP1 as my primary monitor.
