However, when you now try to reenable the internal monitor again (so having an extended desktop with both monitors), the external monitor goes black and both screens stay off. Looking at Xorg.0.log via SSH shows that some part of Xorg or the nouveau driver crashed. This happens both in 32 bit and 64 bit version of 12.04 and both in a fully updated system as well as when started as live system from USB stick. One way to prevent this from happening is to use xrandr --auto, then both monitors are in clone mode and you can use the graphical tool again for setting up your desired configuration.
