I put this into google: "systemd X windows Debian" and was
brought here:
https://www.debian.org/doc/manuals/debian-reference/ch07.en.html
I executed the suggested command:
# dpkg-reconfigure --priority=low x11-common
...and then decided to throw all caution to the winds:
# startx
Saints Be Praised! I had a colorful image in front of me, and my
icewm had been neatly launched. No mouse problem. OMG!
But it only works for root.
:(
We're almost there kids. Please bear with me, as I know I have
been testing the patience of some of you.
Thank you
