I've heard those words before, and that's about as far as my experience with them goes. From the lock screen, I found options for
- Cinnamon (Default)
- Cinnamon (Software Rendering)
- Cinnamon on Wayland (Experimental)
I got everything working again, so it's too late to find out if one of those would've worked, but thanks for teaching me something new!
Edit: Oh shit! Selecting a different DE from the list brings me back to the same session? All my apps are still open when switching DEs under the same user! New rabbithole to explore! Any beginner friendly links to share?
