nm-applet icon missing

[sorindumitru]

Binary package hint: network-manager

Nm-applet icon is missing, maybe it crashed. Got this from .xsession-errors:
** (nm-applet:2754): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager.

After checking a little bit a think it's a problem with the icon. The applet is there just that it doesn't have an icon, so is very hard to click on it.

I had this issue in Lucid and the fix for me was to comment out the last line "iface eth0 inet dhcp" in /etc/network/interfaces and then reboot. After that the nm-applet started to manage the wired interface and this allowed the icon to be displayed. The way I found this was I miss the sound icon by a pixel and the hidden network manager icon said "Wired Network not managed".

miked1981 workaround worked for me.

miked1981's workaround did it for me, too.
Also, there's an alternative workaround described, which also worked for me:
In the file /etc/NetworkManager/nm-system-settings.conf change "managed=false" to "managed=true", then type in the terminal "killall nm-system-settings" and reboot. In addition, I had to drag the three-dot-symbol for the notification area a bit to the left to create more space for the network-manager-icon to show up.

As far as I can tell, the problem is that when the network manager is in some particular, unknown, state, the applet is rendered without an icon, and only a single invisible pixel area for the purposes of bringing up left and right click menus.

This issue is sometimes confused with people who've removed their notification area. Most nm specific 'solutions' have unreliable results — they push nm into a state with an icon for some people but not others.

The only solution that worked reliably for me under lucid was to restart the network manager, but that only worked until the next reboot. Later, for some unknown reason, the machine would boot with the applet visible.

The underlying problem is that the applet permits begin rendered in the notification area without an icon. Instead, it should generate a standin and emit a warning to stderr so folks have a chance at reporting something closer to the real problem.
