Hello.

Out of interest, without me knowing why, in the second-last system 
updates on two of my computers, running Linux Mint Mate 21.1, for 
whatever reason, in the listed updates, was cinnamon desktop environment 
(it was cinnamon-common, from memory), which had me worried, in case the 
desktop environment got switched (without my authorisation) from mate to 
cinnamon.

But, after the updates, both computers have both the login screens and 
the desktop environment, unchanged, and still booting into mate.

So, as a relatively unknowledgeable person, I think that maybe the 
changes that you have encountered, is caused by something different to 
having the cinnamon desktop environment included in the system updates.

I accept that I could be wrong.
