If this is the case, what is the solution?

If "session" is connected to some property of the desktop, then it should grab
the VNC desktop which is what is running and where the request to show the app
(GParted for example) comes from.

If it tries any other (physical) desktop then there is none in this case AFAICT.

The behaviour when starting GParted in VNC is to show a circular mouse pointer
that rotates, probably a timeout of some kind. After a while it disappears and
nothing else happens.

If I start GParted in the physicak computer desktop then a pop-up dialog is
shown where I am asked to enter the sudo password. This stays on indefinitely so
there seems to be no timeout. When pwd is entered GParted loads normally.
