Enable remote desktop for Gnome from command line?
I am trying to set up some automation scripts to set up a Linux environment. I would like to enable remote desktop sharing without the user having to actually use the GUI to do so. My plan is to write a batch script that maybe edits some file to do this automatically, if possible.
