Hi Bob question on getting TurboVNC running

The base problem appears to be that running vncserver on the physical
machine terminal results in /usr/share/xsessions/xubuntu.desktop being
found and used
as required by the window manager.
The successful start log shows:
xstartup.turbovnc: Using 'xubuntu' window manager in
xstartup.turbovnc: /usr/share/xsessions/xubuntu.desktop
xstartup.turbovnc: Executing /etc/X11/Xsession "startxfce4"
in SSH or Telnet terminal window vncserver is unsuccessful and the start
log shows:
xstartup.turbovnc: The session desktop file for the default window manager
was
xstartup.turbovnc: not found at:
xstartup.turbovnc: /usr/share/xsessions/gnome.desktop
xstartup.turbovnc: /usr/share/xsessions/ubuntu.desktop
Killing Xvnc process ID 10292
Indeed /usr/share/xsessions/xubuntu.desktop does exist but
/usr/share/xsessions/gnome.desktop
/usr/share/xsessions/ubuntu.desktop
do NOT exist
I'm wondering why vncserver is trying to use the nonexistent desktops to
start when in SSH or Telnet terminals?
Thanks,
Phil
