Improvements for convenient switching of desktop sessions


I like the feature “fast user switching” for test and checking purposes generally. I am looking for ways to make this technique a bit more convenient.

It seems that the button “Switch user” is often also connected with the function “Lock screen”. Do you know an approach so that I can start another desktop session without a new login and without an immediate screen lock because I was authorised before already?

Is my feature request affected by recent developments for software components like “ConsoleKit” and “systemd-loginctl”?
