I have used the Xfce panel Network Manager applet for many years.
Tonight, I noticed that it has disappeared (!).


But, the machine is connected to my LAN:

Looking in the the Xfce panel Application Menu, I am unable to find
Network Manager.


Looking at the Debian WIKI page "NetworkManager":

https://wiki.debian.org/NetworkManager


It looks like the Network Manager daemon is running:

2024-04-14 04:32:49 dpchrist@laalaa ~
$ ps -A | grep -i network
828 ? 00:00:00 NetworkManager


nm-applet(1) looks like the program I want (?). Attempting to start it
via a terminal has no effect:

2024-04-14 04:40:25 dpchrist@laalaa ~
$ which nm-applet
/usr/bin/nm-applet

2024-04-14 05:27:05 dpchrist@laalaa ~
$ nm-applet

2024-04-14 05:27:08 dpchrist@laalaa ~
$


RTFM nm-applet(1), it seems the desktop session manager is failing to
start nm-applet(1) (?):

2024-04-14 04:58:49 dpchrist@laalaa ~
$ man nm-applet | cat
...
DESCRIPTION
nm-applet is a GTK-based GUI applet to monitor network status
and devices and to start and stop network connections managed
by NetworkManager. nm-applet is normally started at login by
the desktop session manager and does not need to be run manu-
ally. nm-applet conforms to the XDG System Tray specification
and requires that the desktop environment provide a System Tray
implementation in which the applet will be embedded.


I am unable to find relevant error messages under /var/log.


The network Connection Editor can be run via a terminal:

2024-04-14 04:55:29 dpchrist@laalaa ~
$ which nm-connection-editor
/usr/bin/nm-connection-editor

2024-04-14 04:55:38 dpchrist@laalaa ~
$ nm-connection-editor


Does anyone know why the Network Manager Xfce panel applet is missing,
how to get it back, and/or how to start it some other way?

Hi David,

I can't speak for XFCE, but certainly for Mate there was a time when multiple notification area panel widgets were available, not all of which would show everything to be expected. Is that a possibility?

Does

$ ps aux |grep nm-applet

show anything? Before or after

$ nm-applet

?

I suspect that if nm-applet doesn't start, you won't see any output
from that command.

I have used the Xfce panel Network Manager applet for many years.
Tonight, I noticed that it has disappeared (!).

I compared the problem machine against another with a working Xfce panel Network Manager applet, and discovered that the Status Tray Plugin was
missing. I may have deleted Status Tray Plugin while cleaning, but did
not notice the change immediately (?).


So, I added Status Tray Plugin and now Network Manager has returned.

Glad you solved it and thanks for explaining how.

I hadn't twigged that "status tray" was a separate thing to "notification plugin" in XFCE (hence my earlier nomenclature) though on inspection, there it is indeed!
