A GUI for the RaPi/Octoprint can be installed by running sudo ~/scripts/install-desktop.
The user is then presented with the option to automatically have the GUI start on boot, or not. In my case I chose "no", because I will only need the GUI on occasion, and I do not wish it to interfer with printing.
Question: How does one actually start the GUI? I have tried "startx" with no success.
In my specific use case, I would like to be able to start the GUI via SSH from another machine. (I have a large touchscreen connected to the Pi/Printer, no keyboard.
