multiple-monitorsunity
On my dual screen display I have a Unity Launcher on the left hand screen and also on the right hand screen. Both work perfectly fine.
However, I don't want this second launcher present on my right hand screen. How could I remove this? If it matters, I'm using NVIDIA drivers with a TwinView setup.
Currently Unity sits itself down at 0,0. Supporting right monitor as primary is simply not implemented yet. It will be by release.
Install disper by clicking here or type sudo apt-get install disper in a terminal
Create a new launcher by right clicking on your desktop and selecting "Create Launcher..." Set the name to whatever you want, and the Command to disper -d auto -e
Click Ok
Whenever you plug in or unplug your external monitor, just double click the launcher icon.

You can now.
Open up Display preferences, and then you can choose between having the launcher on one display or all of them.
This dialog also allows switching on or off the sticky edges (i.e. the mouse slowdown) between the displays.
