That seems to show it's running from the outset, just not being displayed on the panel.

Does rebooting (or logging out and in again) bring it back?

No.

OK. You may have checked this already, but in case not, if I install XFCE and go to

Settings > Session and Startup > Application Autostart

there is an entry in the list called

"Network (Manage your network connections)"

It is checked.

which shows a tooltip of "command: nm-applet"

Command: nm-applet

Might this somehow have become unset?

I'm not sure if it's possible for GUI config helpers to become detached from actual settings - this seems to describe the relevant locations:

My WAG is that nm-applet is failing to start, but I have been unable to
find if and where any error message is reported.

My WAG is that nm-applet is failing to start, but I have been unable

What are the permissions on the nm-applet binary? maybe it doesn't have permission to execute, or the process which starts it doesn't have
permission.

My WAG is that nm-applet is failing to start, but I have been unable to

There is apparently a long history of nm-applet/XFCE panel-related issues (and not many great answers), as evidenced by such as

https://bbs.archlinux.org/viewtopic.php?id=161998

https://forum.xfce.org/viewtopic.php?id=6105

https://superuser.com/questions/900490/networkmanager-icon-on-notification-area-is-not-present

If you get ps output like this directly after a reboot:

$ ps aux | grep nm-applet
dpchrist 1518 0.1 0.2 426500 35380 ? Sl 16:06 0:00 nm-applet

then I don't think the issue is with the starting/running of nm-applet itself, but rather some issue with the notification plugin, which I'm not sure how to begin troubleshooting. I reluctantly abandoned XFCE partly due to panel instability some time
ago.

The advice in the final link to rm -rf ~/.config/xfce* might be a bit extreme, but I might try renaming it to force a rebuild on next login, and possibly reinstall task-xfce-desktop (or selected packages)

Would be interesting to hear from anyone with XFCE panel troubleshooting experience.

Best wishes,
Gareth

I tried:

1. Remove Notification applet, restart, add Notification applet, no
Network Manager, restart -- no Network Manager.

2. Look at /etc/NetworkManager/NetworkManager.conf

2024-04-18 02:40:49 dpchrist@laalaa ~
$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

Change it to:

2024-04-18 02:43:35 root@laalaa ~
# cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

Restart -- no Network Manager.

Verify /etc//NetworkManager/NetworkManager.conf:

2024-04-18 02:45:05 dpchrist@laalaa ~
$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

If you get ps output like this directly after a reboot:

$ ps aux | grep nm-applet
dpchrist 1518 0.1 0.2 426500 35380 ? Sl 16:06 0:00 nm-applet

then I don't think the issue is with the starting/running of nm-applet itself, but rather some issue with the notification plugin, which I'm not sure how to begin troubleshooting. I reluctantly abandoned XFCE partly due to panel instability some time

The advice in the final link to rm -rf ~/.config/xfce* might be a bit extreme, but I might try renaming it to force a rebuild on next login, and possibly reinstall task-xfce-desktop (or selected packages)

Move aside the ~/.config/xfce4 directory:


2024-04-18 02:50:20 dpchrist@laalaa ~
$ ls -ld .config/xfce4/
drwxr-xr-x 8 dpchrist dpchrist 4096 Apr 18 00:45 .config/xfce4/

2024-04-18 02:50:23 dpchrist@laalaa ~
$ mv .config/xfce4/ .config/xfce4-20240418-180045


Restart -- screen with wallpaper alone.


Right-click on desktop -> Applications -> Settings -> Panel brings up
the Panel Preferences application. The Items tab shows my previous
settings. Fumbling around, I am unable to get that panel to display
(?). If I create a new panel, I am unable to get it to display (?).


Open a Terminal and look if Xfce created a new configuration directory:

2024-04-18 02:57:31 dpchrist@laalaa ~
$ ls -ld .config/xfce4*
drwxr-xr-x 7 dpchrist dpchrist 4096 Apr 18 02:57 .config/xfce4
drwxr-xr-x 8 dpchrist dpchrist 4096 Apr 18 00:45
.config/xfce4-20240418-180045


Yes, it did. Compare the old directory to the new directory:

Move the old directory back:

Restart -- back to Xfce panel with no Network Manager.

Would be interesting to hear from anyone with XFCE panel troubleshooting experience.

Agreed.

Hi David,

Starting from Mate DE only and some old (bookworm) XFCE config files, if I:

$ sudo apt install task-xfce-desktop

then log out and into XFCE, I get an XFCE desktop with wallpaper, desktop icons, panel, main menu, launchers, window buttons, notification area.

Then I:

$ mv ~/.config/xfce4 ~/.config/xfce4.old

then logout and into XFCE again, I get wallpaper, desktop icons, panel, main menu, window buttons, notification area, but only non-functional launcher placeholder icons.

$ diff ~/.config/xfce4 ~/.config/xfce4.old
Common subdirectories: /home/user/.config/xfce4/desktop and /home/user/.config/xfce4.old/desktop
Only in /home/user/.config/xfce4.old: panel }
Only in /home/user/.config/xfce4.old: src } <-- these are subdirectories
Only in /home/user/.config/xfce4.old: terminal }
Common subdirectories: /home/user/.config/xfce4/xfconf and /home/user/.config/xfce4.old/xfconf
Common subdirectories: /home/user/.config/xfce4/xfwm4 and /home/user/.config/xfce4.old/xfwm4
$

(though there probably wasn't much there to start with)

I'm not sure what would cause this difference in behaviour (though wonder if this might suggest more amiss with your XFCE installation) and I will watch this thread with interest.

Also I just "rediscovered" that reinstalling task-xfce-desktop doesn't reinstall those packages which it brings in in the first place, though I'm sure you knew that :)

Sorry I couldn't be of more help.

Best wishes,
Gareth

Thanks for the suggestions. We have more information now. :-)

I do not know what binary starts nm-applet, but here is a WAG:

Can PPID tell you?

Yes. xfce4-session is the parent of nm-applet:

Restart -- back to Xfce panel with no Network Manager.

Try to create a new system user and log in. Is nm-applet present?

Logging in using another previously working account produces the same
result -- Xfce Panel displays Notification Plugin (bell icon), but no
Network Manager icon.


Creating a new account and logging in produces the same result.

Hi,

Not sure this command is super-useful:

Another thing: did you look into ~/.xsession-errors?
(Sorry if this was already mentioned and I missed it.)

More involved: if you can't find any trace of the applet doing
something, maybe rebuilding the package after adding a few fprintf()
calls would help.

Please see attached copy of ~/.xsession-errors, taken immediately after
system restart and login.


"nm-applet" does not appear in .xsession-errors, but there are plenty of
other warnings and error messages. Perhaps the failure of nm-applet is
a symptom of a more fundamental failure (?).

I think it is time for a bug report.
