I found out that some apps are working, but if I'm remembering correctly, usually the morph browser that I used in Ubuntu touch as the vnc client, gave me problems. If Morph would be more modern it would work, but sometimes when I needed to enter some text somewhere, Morph wouldn't give me a keyboard etc
I was thinking about Guacamole or DWService
Could't get it going...
(did not try Anbox / teamviewer by the way)
