Title:
External display monitor not recognized
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
xrandr lists four disconnected DPs (though my laptop has zero Display
Ports) but does not list an HDMI, which is what I use to connect
external monitor. Cable is sound b/c I have a dual boot setup and
Windows recognizes the display without issue.
Using Ubuntu 22.04.1 LTS
I expected OS to recognize that I have a an HDMI port or alternatively that
something is plugged into it
OS does not seem to acknowledge same
