I installed 14.04 on a desktop today, did not have it download updates 
as an installation choice, and then after booting into the finished 
installation, manually ran update-notifier to start the daemon.  It did 
not notify me about any updates.

Meanwhile, back on the laptop, it offered me updates *once* after I 
manually ran /etc/xdg/autostart/update-notifier.desktop modified with 
Exec=dbus-launch update-notifier.  I did not install any of the updates 
but simply X'ed out of Software Updater.  After a number of reboots, I 
have not been able to get it to offer me updates again regardless of the 
method I used to get update-notifier started.

By the way, I'm assuming that LXDE does something to modify the default 
behavior of the update-notifier daemon.  That is, by design it presents 
a tray icon (says the update-notifier readme and the Synaptic 
description).  But in Lubuntu, as far as I know there has never been a 
tray icon, but update-manager starts instead to offer the updates.  If 
someone knew about that mechanism it might provide a handle for more 
troubleshooting.
