For troubleshooting purposes, inxi -G with no other options is little short

inxi is broken, so should be upgraded from upstream using the -U switch as
superuser after unblocking the -U switch in /etc/inxi.conf, or by upgrading
the Debian inxi package to the backports version. e.g.:
# inxi -GSaz --vs --za --hostname
Thanks for this advice. It revealed what I believe I need to know: What is the name of the interface for the display that I want to activate?
I saw a message that advised putting "video=HDMI-A-1" (which is the name revealed by inxi) onto the vmlinuz line using a GRUB_CMDLINE_LINUX*= line in /etc/default/grub. Would that make that display the only one, or simply make it "exist" along with ones that are detected to be working during boot?
inxi reported
empty: DP-1, DP-2, HDMI-A-1, HDMI-A-2, HDMI-A-3, HDMI-A-4
There's only one HDMI connector, so I assume the name I ought (maybe) to put into the vmlinuz option is not DP-* or HDMI-A-[234].
