I cannot see an nm-applet in my GNOME panel, only in the process list.
Killing nm-applet and restarting it does not help. It remains invisible.

If you start nm-applet from the command line, do you get any error messages?
Do other apps show up in the system tray?

Wild guess: broken icon cache file?

Michael

Yes.

No. With strace nm-applet seems to be looping in a poll. Maybe
dbus?

In the GNOME panel? Yes.

How do I know? There is a command
"gtk-update-icon-cache --validate", but I'm not sure which
arguments I would need. I tried
"gtk-update-icon-cache -v /usr/share/icons/gnome" as root, which
did not gave any output. Btw. strace nm-applet does not show
anything with "icon" in it.

Btw. nm-tool shows all kind of information about APs etc., but I also get a warning:

** (process:4105): WARNING **: error: failed to read connections from org.freedesktop.NetworkManagerUserSettings:
    The name org.freedesktop.NetworkManagerUserSettings was not provided by any .service files

No idea, whether this is related.

This bug effects me too.

I was able run lower-level commands to work around it, but that required me
to do online searches for the commands I needed since I'm a
less-than-proficient Linux user.  If the effected computer were my only
internet access, this bug would have felt very severe to me.

My blog post about this topic might help:

Hi!

There is a bug, if nm-applet is already running by first logged in
user, it will not be shown in notification area to second one.
In console it will say that "An instance of nm-applet is already
running". After rebooting this situation can be fixed because there is
only one logged in user.

Dear Maintainer,

I have do upgrade on jessie few hour ago, after i upgrade i found my nm-applet has gone and i try run nm-applet with terminal and it gave error

and i try /etc/init.d/network-manager force-reload and it still not show the nm-applet

** (nm-applet:18443): WARNING **: Could not initialize NMClient /org/freedesktop/NetworkManager: Launch helper exited with unknown return code 1
** Message: applet now removed from the notification area
** Message: applet now embedded in the notification area

** (nm-applet:18443): WARNING **: fetch_connections_done: error fetching connections: (25) Launch helper exited with unknown return code 1.

** (nm-applet:18443): WARNING **: Failed to register as an agent: (25) Launch helper exited with unknown return code 1
** Message: applet now removed from the notification area

thank you
best regard

Answering questions from earlier in the bug report.

Currently I am the only user logged in other than daemons.

Logging out and back in again does not fix it.
Rebooting does not fix it.

Running nm-applet from the command line works until I log out.

Using Gnome in Classic mode.

There is no error or warning message if I run:

    sudo /etc/init.d/network-manager force-reload

In addition, nm-applet does not show up in the programs listed in
the "Startup Application Preferences" dialog.

In /var/log/daemon.log I found:

Have no idea where ':1.99' is coming from.
