I'm using 15.3 Lite on a Dell laptop that's connected to a Samsung monitor via HDMI. I want to switch to using the monitor as my primary display, so the task bar shows up on it. However, even after going into Settings -> Display -> General and setting "Primary Display" for the monitor to on and clicking "Apply", nothing happens. The setting is saved and it stays that way even after restarting, but everything still shows up on the laptop screen and the monitor is just the second display.
Is this something that can be checked or am I misunderstanding the use of the "Primary Display" feature?
The dual monitor setup page on the Ubuntu website states:
The primary display is the one with the top bar, and where the Activities overview is shown.
I would expect that to refer to the task bar over in Zorin OS.
