the problem too.?? I have found the issue is setting the

The SSH and VNC stuff listed below can be skipped for now if you
choose to connect a monitor, keyboard, and mouse to your pi. Since
I
always run
and access my pi from my Mac when in the shack and with a tablet
in
the field, these steps are critical to my setup. If you plan to
run
your pi headless, I recommend completing the SSH & VNC steps
now.
NOTE:
You will need to plug your pi into your router via a cat5 cable
and
know the pi's IP address. Finding your pi's IP address
on
your network is beyond the scope of this document. Google is your
friend :)
-
Flash
SD card See Fig 1
-
-
Insert
SD card & boot the Pi
-
SSH into the pi. See
-
Reboot
-
Use on your PC to connect to pi
-
Complete
setup wizard
-
Change Hostname (This step can
be skipped)
After the setup wizard is complete,
open a terminal window and verify everything is up to date with
sudo apt-get update
sudo apt-get upgrade

I thought I had followed directions to make my Pi 4 headless
(in fact, have a headless Pi 3)... VNC enabled and remote
access, however one issue:
When I disconnect the monitor (mini HDMI jack) and then try to
access via VNC, I get an error saying it Cannot show the
desktop. It's not happening
right now when I unplug the monitor, but seems to happen at
some stage after a reboot. I have Xastir installed, I also have
raspberry-noaa-v2 installed.
For Xastir, I did not use "build a pi" but did follow one of the
KM4ACK youtube videos, not running direwolf, I have the pi
connected to a Yaesu TH-D72A,
which has a built in TNC.
Thoughts appreciated!
