Sorry if this is a duplicate - email issues...
I applied the latest updates today, second monitor capability is still
I plug in the HDMI cable, go to system settings --> Display and it only
show the laptop screen.
The Cinnamon desktop continues to work flawlessly per auto-adding the
second monitor as soon as I plug the HDMI cable in, thus seemingly
confirming it's a KDE issue and not a Kernel issue. I do prefer KDE
Plasma over Cinnamon, but I need the second monitor to work. Anyone have
any thoughts on debugging this?
Lenovo X1 Carbon 3rd gen, lspci listing below, thanks in advance
