How truly strange.

When I swiped-and-right-clicked your thread title and then picked "search google for..." over 100K hits came back. And several hits from the very first page seem to answer exactly this question.

It is kind of "strange", that the searches the OP did do not yield any solution,
Debian 8 Cinnamon - How to change login background?
I don't know anything about "Cinnamon", so I did some search last night as well,
something that confused me, the first results say the are for https://wiki.debian.org/LightDM
and I am not sure if "LightDM", works the same as "cinnamon", but there also were a lot more results, it seemed to me though, the instructions could be applied to cinnamon as well, but then again since I do not know anything about Cinnamon, nor LightDM, as far as that goes, I don't know what else to say that might help.
However what I do, if and when I want to change configurations, or learn more about "mate" , which is what I am using.
I use this command first:

Code: Select all

$ locate mate | less
 

I use the "less" option, because the results are several pages, and using "less" makes it easier to look through them. Some of the first results are:

Code: Select all

 /home/garry/.cache/mate/background
/home/garry/.config/mate
/home/garry/.config/mate-session
/home/garry/.config/mate/backgrounds.xml
/home/garry/.config/mate/engrampa

I think the same could be applied to "Cinnamon", there also probably are documents, etc. that help explain how to change, or configure the backgrounds, log in settings, etc,..
Copied from :https://wiki.debian.org/LightDM#See_also

LightDM configuration file is found at /etc/lightdm/lightdm.conf

Logic tells me,

Code: Select all

 /etc/lightdm/lightdm.conf 

maybe I try:

Code: Select all

/etc/cinnamon/cinnamon.conf

Or if that does not work:

Code: Select all

locate cinnamon | less 

Then look for the background configuration files ?
If all of the above is to complicated, I guess the OP just needs to wait, and hope some one posts a step by step tutorial on "How to configure Cinnamon Log in screen"

Wow, and now based on this, all though it is "fedora", it does show me, that "lightDM" is the display manger that "cinnamon" uses, .. so this (posted at the top as well) should be use full:

This gave me a clue, that maybe the searches I did last night were valid, so it encouraged me to do a little more, and now, in spite of the fact that I knew absolutely nothing about "Cinnamon", I am pretty sure , if the OP read the material on the wiki they will be able to change the background, on there Display Manager.

I'm not sure if cinnamon is configured with lightdm or gdm3 in jessie, it's an either/or recommendation...
https://packages.debian.org/jessie/cinnamon-core

So run the following...

Code: Select all

apt-cache policy lightdm-gtk-greeter

If it returns that it's installed, you can just set the path in /etc/lightdm/lightdm-gtk-greeter.conf (the Wiki page needs updating, apparently)...

Code: Select all

[greeter]
#background=/usr/share/images/desktop-base/login-background.svg
background=/home/hhh/Pictures/wall.png

Yes that confirmed that LightDM was installed with cinnamon.

Yes this worked perfectly on Jessie 8.2 Cinnamon! The login background changes immediately upon logging out.

Big thanks to hhh.

Sorry gary and dason, I was searching like a noob and assuming cinnamon advice for other distros wouldn't be relevant to my install, my bad!

You're more than welcome.

No problem, that was part of what confused me last night, when I did a search, all the results were for "LightDM", and I did not even bother to post them, I was not sure either, if "LightDM" even applied to "Cinnaman", then later today, I found that it did.
Any way, it turned out good, and was not all that complicated.
