Doesn't work so well for Xpra 3.

I don't know what permissions or ownership you have set on this directory. The standard location for 'xpra' group sockets is '/run/xpra'.

It's not clear to me what you were expecting or what actually happened. Have you checked the obvious: logging back in after adding the 'xpra' group perhaps? > First question: Is there a wiki page or other document that outlines the > procedures for using Xpra 3 under a system account to be shared by multiple > users? No, but feel free to create one. The man page is the reference and should always be up to date. > Second question: What would be the equivalent Xpra 3.0.9 command for the > Xpra 1 command shown above? This simple command works for me and allows other members of the 'xpra' group to connect to the session: xpra start :42 --socket-permissions=660 --mmap-group=xpra --sharing=yes (you can then add your audio, system-tray, etc options - those are not relevant to this question, the syntax is the same as before) Cheers, Antoine > > Much appreciated. > > Eric. _______________________________________________ shifter-users mailing list shifter-users@lists.devloop.org.uk https://lists.devloop.org.uk/mailman/listinfo/shifter-users
