Setup VNC at Ubuntu Jaunty Server PV DomU at Xen 3.4 Dom0 (kernel 2.6.30-rc1-tip) via IP6v

Well known schema ([1]) tuning gdm.conf and running Xvnc via xinetd worked fine for Ubuntu Hardy and Intrepid PV DomUs fails for Ubuntu 9.04 Server PV DomU . Setup vncserver to start via /etc/rc.local and /usr/bin/gnome-session via ~/.vnc/xstartup known as a way to manage on Debian Etch. I’ve also noticed :-
Remote Desktop Viewer VNC over IPv6: works on Ubuntu 9.04 Jaunty (Alpha 6)
Yes IPv6 works:-

Auto detection Ubuntu Jaunty PV DomU from another remote Intrepid Server on the same LAN :-

UPDATE on 04/21/2009
Activation Remote Desktop access causes vino-server to start up
automatically. As appears it’s PPID is PID of /usr/bin/gnome-session. Vino-server stop/start via command line :-

gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled false
gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled true

Activating remote access to Jaunty Server PV DomU via old fashioned vnc connection ( still required).

Tuning /etc/rc.local

root@ServerU904:~# cat /etc/rc.local
#!/bin/sh -e
# rc.local
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other

root@ServerU904:~# cd .vnc

Tuning ~/.vnc/xstartup file to start gnome-session immediately
at remote vncviewer’s login to Ubuntu Jaunty PV DomU.

root@ServerU904:~/.vnc# cat xstartup
# Uncomment the following two lines for normal desktop:
# exec /etc/X11/xinit/xinitrc
/usr/bin/gnome-session &
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
twm &

Another version of ~/.vnc/xstartup :-

# Uncomment the following two lines for normal desktop:
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
/usr/bin/gnome-session &
# twm &
