Hi Aaron,
I tried issuing vncserver from an SSH terminal and the VNC server also
failed to start. The ending lines of the unsuccessful logfile are:
Errors from xkbcomp are not fatal to the X server
xstartup.turbovnc: Creating new session bus instance:
xstartup.turbovnc:
unix:path=/tmp/dbus-AuF7HAlcQZ,guid=087f3dae01918291221bb56567b585ff
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

#################

and the corresponding lines from a successful star of vncserver are:
Errors from xkbcomp are not fatal to the X server
xstartup.turbovnc: Creating new session bus instance:
xstartup.turbovnc:
