There's some inexpensive monitors that are on the cusp between raspberry pis and PC accessories. For the latter it's mostly system status - temperatures, network traffic, etc. I know at least one of these screens has a windows app that provides this information.
This should be easy to do on a Linux desktop, right? Alas I was a novice X-mage in my youth and could (and did) set up multiple independent sessions at the time with the introduction of DBus and Wayland all of those skills are now moot.
So the question is how can I set up a separate Wayland session? (Or separate X and Wayland sessions). It's fine for it to be in kiosk mode and locked to a browser - I don't want to raise my X/Motif skills from the dead!
I can immediately rule out the obvious solution - simply adding this monitor to my set of displays. I tried that but the system got very confused with three displays - in fact it would only show two until I explicitly added the third. I have a 4-port video card and I will use 3 displays sometimes but it requires some care-and-feeding. With two displays I'll often drop from "join" to "mirror" after an idle period but everything is predictable. With three displays it seemed to shuffle the content in unpredictable ways.
(This may be due to this being a pretty old video card, probably dates to shortly after 4k/30s was first available.)
In the worst case I can use a dedicate RPi - and may need to do that anyway if I can't have the video card support separate Wayland/X sessions - but I would prefer to just hang it off my desktop if possible.
