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.

FWIW, update-alternatives isn't (directly) related to the other
topics upstream.

It's intended to manage groups of workalike "applications", for example
bash, dash, etc. as alternatives to sh, or vim, elvis as alternatives
for vi.

It does so by juggling symlinks somewhere in /etc/alternatives. It's
smart enough to also juggle the relevant man pages, so that if you,
e.g. use "vim" for "vi", "man vi" will show you the vim man page.

I'm looking for something that aims to answer "What can
update-alternatives do for me today?". IOW the manpage gives fine
details but no sense of perspective.

See "man update-alternatives", or this entry [1] in the Debian

It's a Debian-specific thing.

What alternatives does for you? Mostly it does its job silently,
without complaining ;-)

That is the type of page I was looking for. I think the links there will be valuable.

There is a "broken link" under "See Also"
Clicking on [ http://www.debian-administration.org/article/91 ] yields:

This site was born in late September 2004, and has now reached 13 years of age
and that seems to be a fitting time to stop.

I believe a good link would be
[ https://web.archive.org/web/20140406045047/http://www.debian-administration.org/article/91/ ]

Even though anyone can modify a wiki, I don't know enough about the topic to be comfortable doing it.
