The network manager nm-applet
has disappeared from the unity panel of my Ubuntu 14.04. When I try to run it from the commas line, I receive an error:
$ nm-applet
nm-applet-Message: using fallback from indicator to GtkStatusIcon
(nm-applet:6409): nm-applet-WARNING **: Could not find ShellVersion property on org.gnome.Shell after 5 tries
I do not know if it is directly related but ever since this, running System Settings-> Network does not display 'Mobile Broadband' even though the datacard is connected to the system. The datacard does not work any more.
EDIT: The following command as suggested by user 'mkayaalp' also gives an error:
$ nm-applet --shell-debug
nm-applet-Message: using fallback from indicator to GtkStatusIcon
(nm-applet:6848): nm-applet-WARNING **: Could not find ShellVersion property on org.gnome.Shell after 5 tries
nm-applet-Message: PID 0 (we are 6848) sent signal 2, shutting down...
(nm-applet:6848): GLib-CRITICAL **: Source ID 107 was not found when attempting to remove it
EDIT2:
The problem of the icon for nm-applet
not appearing on the unity panel is not unique to it. This problem also persists for 'Psensors' even though in options it is set to show on the unity panel.
P.S.: Searching on google and on askubuntu.com mainly brings up results regarding Lubuntu 14.04.
sudo nm-applet
is what I usually do to fix them.
