nm-applet icon missing
 

Hello everyone,

I am completely new both here and in Linux. I carefully read the threads where you explain where to post what, and even searched for previous postings which might have already answered my question, unfortunately, I still got the problem.

Since my distro is CentOS 5.5, I decided to post here, hope it was the right decision (if not, please let me know where I should have posted).

So as the subject says, I installed CentOS and can't manage to make the nm-applet icon show on the notification area.

I read previous threads about this, which suggest that perhaps nm-applet is not running, or that perhaps I did not add a notification area to the panel, or that maybe nm-applet --sm-disable is not showing on sys-sessions. Unfortunately, all the above is ok, i.e, nm-applet is running, I do have a notification area and "nm-applet --sm-disable" appears as it should in the right place.

Do you have any other suggestions?

Many thanks in advance.

Hello, if I give more details maybe someone can help me? I tried to do a killall gnome-panel and then check .xsession-errors to see if I could get a clue of what is wrong. Of course, I took this tip from someone else and even more "of course", I did not understand the result. Here is what is said, maybe it will give the experts a clue as to why my nm-applet icon is not showing?

cat /home/me/.xsession-errors gives the following:

** (nm-applet:4319): WARNING **: No connections defined

** (nm-applet:4319): WARNING **: Invalid return value type: GPtrArray_DBusGObjectPath_

I don't know if this is related or not, can you please please help me?

Thanks in advance.

When the nm-applet icon doesn't show, it means either nm-applet isn't running, or NetworkManager isn't running. Open a terminal window and enter to see if nm-applet is running, and
to see if NetworkManager is running. If Networkmanager isn't running, then, as root, run
I had a problem today in Fedora 14 alpha with nm-applet not showing up or running even though NetworkManager appeared to be running. My fix was to downgrade the versions of NetworkManager, NetworkManager-glib, and
NetworkManager-gnome.

WOW!!! it worked, can't believe it - so many thanks!!!

Now the weird thing is that both network manager and applet appeared as running, but it seems they weren't after all. After I did a start on /etc/init.d/NetworkManager the icon appeared!

[m@localhost ~]$ ps ax | grep nm-applet
3257 ? Ss 0:00 nm-applet --sm-disable
3584 pts/1 S+ 0:00 grep nm-applet

[me@localhost ~]$ ps ax | grep NetworkManager
3272 ? S 0:00 /usr/sbin/nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf
3586 pts/1 R+ 0:00 grep NetworkManager

[me@localhost ~]$ su

[root@localhost me]# /etc/init.d/NetworkManager start
Setting network parameters... [ OK ]
Starting NetworkManager daemon: [ OK ]
[root@localhost me]#

Why would networkmanager and applet appear as running when actually they weren't?

That is how it works for me (when working properly).

Are you saying that after you did the start on /etc/init.d/NetworkManager it wasn't actually working even though the nm-applet icon appeared?

Restart the system and check if nm-applet shows. If not, then you need to set NetworkManager to start on boot.

I have not checked, but it is possible that if NetworkManager service is not running nm-applet does not show icon.

Hi RockDoctor, thanks for your help - what you told me to do worked. I started networkmanager and the icon appeared. I was just puzzled because BEFORE I started networkmanager, it was showing itself as working and the icon was not there. The I hit restart (after your tip) and the icon appeared.

In any event, case solved, many thanks for the help!

@DrLove73 - how do I make sure networkmanager starts on boot?

Thanks in advance.

System -> Administration -> Server Settings -> Services
or
System -> Administration -> Services

and then make sure you tick NetworkManager ans Save settings.

Manually, you would run (as root):
