I don't see how that would work on Ubuntu either. If there's already a
session for a user, creating another session is going to cause great
confusion and weird happenings.
I don't know what to tell you except that it works. I just VNCed into the
Ubuntu box, and 'ps -ef' tells me I have two sessions running:
mrsam 1883 1846 0 10:00 ? 00:00:00 xfce4-session
mrsam 5411 5408 0 16:37 ? 00:00:00 xfce4-session
And just to make sure I wasn't nuts: I went over to the Ubuntu box and
turned on the monitor: yup, I'm logged in, on an XFCE desktop. And I just
disconnected a VNC session to the remote XFCE desktop.
They are different desktops:
$ tr '\0' '\012' </proc/1883/environ | grep DISPLAY
DISPLAY=:0
$ tr '\0' '\012' </proc/5411/environ | grep DISPLAY
DISPLAY=:1
No problems doing this on Ubuntu.
