I'm a pretty new linux user, so PLEASE bear with me.
I'm using LMDE4 Cinnamon.
So here's my issue:
I have a nice laptop that I've connected to a usb-c hub with two hdmi monitor plugins (into which I have two additional monitors). At the bottom are my specs.
So I can't say that the three monitors aren't working, because they are. And I can extend my desktop onto ONE of the monitors, but the other external monitor simply mirrors whatever is one my first external monitor (rather defeating the purpose of a three monitor set up, at least for my needs).
Anyone have any ideas on how to have and use ALL THREE monitors completely separately? I'm pasting my xrandr under my specs in case that helps.
Thanks much!
