a few weeks ago I updated to Ubuntu Gnome 14.04 LTS (clean install) and I noticed that the network manager icon is missing from the system tray. I have been going through a number of forums, but I couldn't find a solution that would fix this problem. My /etc/network/interfaces only contains the following:
auto lo iface
lo inet loopback
Also, when calling nm-applet from the console it outputs:
nm-applet-Message: using fallback from indicator to GtkStatusIcon
Any ideas on how this could be fixed?
