It works quite well with Ubuntu Budgie, Gnome. I have both on bare metal.
I tried your ppa again twice on Unity, after creating that autostart file. It still gives me a black screen and no wallpaper, same as in the #45 post. What might be the 2 line wallpaper option fix?
The desktop folder works in yours, maybe because you installed Unity over Ubuntu Budgie. What if you uninstall Budgie desktop after that?
EDIT: I just installed Unity over Ubuntu Budgie, but it still gives black screen.
And, a metallic voice keeps on speaking every time I touch anything with the cursor…Back again on Budgie, but that metallic voice is still there. Trying to get rid of it. No idea how to get rid of it.
Not going to experiment with Desktop Folders on Unity 19.04 any more. Would await a new unity ppa.
