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

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:

2024-04-18 02:58:11 dpchrist@laalaa ~
$ diff -rq .config/xfce4-20240418-180045/ .config/xfce4

Move the old directory back:

$ mv .config/xfce4 .config/xfce4-20240418-0257

2024-04-18 02:59:54 dpchrist@laalaa ~
$ mv .config/xfce4-20240418-180045/ .config/xfce4


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

Agreed.
