Comment 21 for bug 1046563

I've recently installed lubuntu 14.04 on a coupla' older PCs and the update notifier icon fails to display in the panel on either of them. I do however see the process 'update-notifier' running (via 'htop'). If I kill the process and start it manually, sometimes I can see a blink or flicker in the panel around the systray but never an actual persistent icon. I've tried unticking "Update Notifier" in the "autostart" preferences and then manually adding "update-notifier" but still no icon. Even after refresh/reboot. However, checking back in 'htop' shows four 'update-notifier' processes running.
