Getting rid of the duplicate launcher  

If you’ve got dual monitors (which you should) you might have noticed the annoying duplicate launcher situation. Basically instead of having just the one launcher you’ve got one on the left side of both of your screens. Anyways, it’s an easy fix, but not one that I could figure out without the internet.

Just head over to Display (search in unity and it pops up) and select which desktop you’d like it to be on. Easy!
