Hello,

If you want the desktop environment to be started automatically
check that systemd is configured to run in graphical environment

If this is already setup, and you can launch your DE with startx,
check also that mate is the default DE with update-alternatives(8)
or you can add the startx command in /etc/profile.



That manpage was intriguing, if not educational. I went searching
for "update-alternatives tutorials". They all referenced Ubuntu and
each covered only one instance.

I'm looking for something that aims to answer "What can
update-alternatives do for me today?".


Have you reviewed any notes regarding what it did for you yesterday?
Yesterday's problems stemmed from installing mate-desktop-environment rather than task-mate-desktop ;{ 



If so inclined, you could review the thread which begins with this

That problem and this week's problems are only loosely related.
I consider the Debian installer has a design flaw in that it does not allow me to install _*ONLY*_ packages required by an explicit depends - it insists on installing some undesirable "recommended" packages. 
I've abandoned that fight for the time being.

For a general overview, I would be hard pressed to improve on the
second and third paragraph above.
I was pointed to [ https://wiki.debian.org/DebianAlternatives ] which, especially with its internal links, spoke to me. 

Thanks
