I have a Mint 22.1 system driving two screens.

I was curious whether there was app that would enable dufferent backgrounds to be displayed on the two monitors.

Naturally I addresed my query to Google's AI that provided three solutions:

Nitrogen
SuperPaper
Hydrapaper

I couldn't get anywhere with the first two and am struggling with Hydrapaper.
I cannot get it to select any file, let alone display it.

Does anyone out ther have any experience with these programs?

I tried taking a sample HDD with multiple distros on it,
and it seemed everything used Wayland, and the choices
for two monitors was "Joined" or "Nothing" (turn off #2 monitor).

Attempts to assign two separate background images, well, there
was no interface to do it.

So I'm Googling, and a Reddit post mentions that Devuan with XFCE
on it, it is using Xorg, and it allows addressing the monitors.
I set that up, made two separate pictures as my background artworks,
and the application in there allowed assigning an image to each monitor.

I haven't tested your "automation" cases in there yet, because
getting that far was pretty tough (the netinstaller failed
to work properly, I ended up downloading a LiveDVD to do the picture).

You would want something with a real Xorg in it (not an XWayland) and experiment with that.

I fired up a LM221 Xfce which uses XWayland, and was able to
set different background pictures on the two monitors. That's
just using the control panel stuff.

I then tried Hydrapaper, and ran into a few errors.

The python module with "flow" in the name, it tries
to make a thumbnail, and it makes an obsolete call to
ANTIALIAS when the newer argument is LANCZOS. I fixed
that, then moved onto the next error. If was failing while
evaluating the path.

hydrapaper -c /home/mint/left.png /home/mint/right.png

The program was expecting files in this case, not dirs,
and even if you use -r for random, you can't seem to specify
two directories in that case.

I was getting closer at that point, but then it was failing
on a GTK call, and my eyes glaze over on those, and
experiment ended.

So if hydrapaper worked, it might have worked in 18.04 or so.
It would seem to me, it was a low priority item and the
person responsible for building it for the repo, just
left it where it was.
