I setup Manjaro on my NUC with a monitor, installed SSH and then went headless. I then went on with installing TigerVNC following the directions in the Arch wiki.
So far, it works like a charm. Firing up VNC on my Macbook will open xfce, three finger swipe left or right on the touch pad allows me to switch from one system to the other. I love it!
Now I’d like to connect a physical monitor to the NUC and move into a dual-monitor setup combing VNC and the physical one. Imagine me sitting on the couch with the Macbook, starting VNC to connect to xfce, turning on my TV that will function as the second monitor to the same xfce session.
Problem is, the TV (or physical monitor), shows only the NUC boot screen and nothing else.
I’m not new to Linux, pretty new to Arch, but I don’t mind tinkering with settings to make things work. I just don’t know what to tinker with.
Edit: When going to Settings>Display it only shows the VNC display, not the external device.
