OK, that’s an interesting issue. I don’t recall adding it and I don’t recall removing it..

Slightly later vm, presumably post some fix.

No idea on that. I’m not sure the package is fully and properly set up to be honest. I don’t have anything to do with that part.

You’re referring to not-pi user names yes? I’ve not tried using any such and I don’t think anyone recommends it because of issues like this. I’ve seen occasional messages on the subject on the Pi forums. To be honest I’d urge you to go there (raspberrypi.org, try the Raspbian forum) to ask about it. The sigline insult below applies to me in this area.
My experience with user privilege issues is using xrdp or vnc to remotely display stuff. We just got that sorted (I think!) in the latest Raspbian.

Guess that’s an issue for Eliot to handle since it is his website.

He is a close friend of General ProtectionError, who is forever reading my disk.

Useful random insult:- Has a one-way ticket on the Disoriented Express.
