+# set up gnome desktop environment for remote access via vnc.
+
+# NOTE: it is important to be running the vncserver as a user who is NOT
+#        already running x windowing system.  otherwise, weird and possibly
+#        bad things can happen, e.g. your apps show up on display zero
+#        rather than on the vnc desktop.
+
+# this script depends on the gnome desktop.  to install the minimal
+# parts of gnome needed (as far as i know), run this command:
+#
+#   sudo apt-get install gnome-panel gnome-settings-daemon gnome-terminal kwalletmanager metacity nautilus
