    Question nm-applet invisible (no icon)

    Hello All,

    I have xubuntu installed on an asus eee pc r101d. Everything except the wifi switch (Fn-F2) was working. Whilst at an airport waiting to get on a plane, I decided to manually switch off the wifi radio from the command line by using
    Code:
    sudo echo -n 0 >> /sys/class/rfkill/rfkill0/state
    The wifi radio switched off and the nm-applet icon disappeared.

    Interestingly the /sys/class/rfkill directory had 4 subdirectories originally (rfkill0 rfkill1 rfkill2 rfkill3) but immediately after issuing the above command, rfkill0 disappeared.

    After rebooting the netbook, the Fn-f2 radio switch now works, there are only 3 rfkill subdirectories (rfkill0 rfkill1 rfkill2) and the nm-applet is present in the notification area (I know this because I can click the empty space) but it does not have an icon, it is, I guess, invisible.

    Does any one know how to re-set the icons for nm-applet on xubuntu?

    Hi Toz,

    Thanks for the reply.

    Code:
    mp035@eeepc:~$ rfkill list
    0: eeepc-wlan: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    1: eeepc-bluetooth: Bluetooth
    	Soft blocked: yes
    	Hard blocked: no
    2: phy0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    mp035@eeepc:~$
    Any clues there?

    Cheers,
    Mark.

    Hmmm, looks okay. Did you change icon themes? It's possible the new icon theme doesn't have a corresponding icon.

    You can also try restarting network manager and nm-applet:
    Code:
    killall nm-applet
    sudo service network-manager restart
    nm-applet &
    This will force nm-applet to update the icon.

    Thanks Toz.

    No theme change, ever. Still running the stock xubuntu 11.04 theme.

    I restarted the nm-applet one more time using your commands verbatim.

    No luck

    Any thing else you can think of?

    Re: nm-applet invisible (no icon)

    Lets see if its generating any errors. In a terminal window, can you run these commands and post back the results:
    Code:
    cat ~/.xsession-errors | grep -i nm-applet
    cat ~/.xsession-errors.old | grep -i nm-applet
    You can also try removing the notification applet from the panel and then re-adding it.

    And, is NetworkManager running?
    Code:
    sudo service network-manager status

    Re: nm-applet invisible (no icon)

    Thanks for all of your help Toz.

    I think this may be a bug in xfce or nm-applet.
    After doing a complete reinstall, the icon was back. After re-applying my xfce setttings which I backed up from ~/.config/xfce4, the icon disappeared again.

    After some fiddling around, I found that if I had the notification area in an horizontal panel the icon was visible, but if I had it in a vertical panel it would disappear.

    I ran your commands regardless, in case you can glean from them which package I should be reporting the bug in.
    Code:
    mark@eeepc:~$ cat ~/.xsession-errors | grep -i nm-applet
    ** (nm-applet:2678): DEBUG: old state indicates that this was not a disconnect 0
    ** (nm-applet:2678): DEBUG: foo_client_state_changed_cb
    ** (nm-applet:2678): DEBUG: foo_client_state_changed_cb
    mark@eeepc:~$ cat ~/.xsession-errors.old | grep -i nm-applet
    ** (nm-applet:2183): DEBUG: old state indicates that this was not a disconnect 0
    ** (nm-applet:2183): DEBUG: foo_client_state_changed_cb
    ** (nm-applet:2183): DEBUG: foo_client_state_changed_cb
    nm-applet: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.
    mark@eeepc:~$ sudo service network-manager status

    network-manager start/running, process 708

    It appears that this is a known bug and was fixed in 0.2.0-0ubuntu4.1

    See: https://bugs.launchpad.net/ubuntu/+s...in/+bug/787977

    What version do you have:
    Code:
    apt-cache policy xfce4-indicator-plugin

    a workaround from this post says that you just need to add notification area to the panel to show NetworkManager

    right click Panel
    select Add new Items
    choose Notification Area
    and a pop up will appear for you to check the box for Networkmanager Applet
    just press OK then
