Network Manager Applet for MATE Desktop – Installing it right

Mate-logoRecently I have been fiddling with MATE Desktop, sleek and lightweight.

Anyhow, I had some problems with network manager and the companion applet. The applet did not appear on the panel and the application was not working properly.

Luckily I found a solution looking on the Ubuntu forum (although I shamefully lost its reference).

Here are the steps:

on a console reinstall both the network manager and the gnome apple with the command sudo apt-get install --reinstall network-manager network-manager-gnome;
open the network manager configuration with your editor of choice (e.g., nano): sudo nano /etc/NetworkManager/NetworkManager.conf and change the line managed=false to managed=true;

make sure that network interfaces file /etc/network/interfaces contains only the basic configuration:  auto lo iface lo inet loopback (you can simply comment the other lines);

restart network manager with command sudo service networking restart;

In case the network manager applet does not show up on mate’s panel try these one of these fixes:

edit the file  sudo sublime /etc/xdg/autostart/nm-applet.desktop, remove the line  AutostartCondition=GNOME3 unless-session gnome, and restart the networking service;
remove the .state file relative to the network manager with command  sudo rm /var/lib/NetworkManager/NetworkManager.state

I hope the procedure can be useful also for someone other out there 🙂

  1. I had a problem with nm-applet that could not get access to the interfaces.
    To solve it I modified dbus-access rights in


    I changed deny to allow for all entries in the section
    policy default.

    Peace 🙂

  2. Solution worked perfectly………..problem solved! Thanks!

    That’s what I love about the Linux Community; there’s always someone out there who’s willing to share their knowledge with us less-experienced users. 🙂

  3. All I did was the 1st step (reinstalling the networking manager) and the step where one changes “managed=false” to ‘true’. And then I restarted the operating system altogether instead of only restarting the service. And it worked. All the other steps were not necessary in my case. So in short, I guess only these two actiosn are enough for the applet to show up. (At least thats what I worked for me) .

  4. I’m intrigued how did you find out about those obscure command under linux cause you have fix my problem . Are you a linux developper ? I have been using linux for a long time and i still learning new stuff every day !

    Thank you for your blog !

  5. Hi Ghislain,
    I am not a linux developer and, just like you, I learn new things about this OS every day 🙂
    Unfortunately, I lost the link to the forum where I found this particular solution.
    Thanks for leaving your appreciation.

  6. Thank you, I had conducted an in-situ upgrade from 12.04 to 14.04 which broke it. You helped me fix it. Brilliant.

    Thank You very much !!

    I was on the verge of reinstalling Mint on my laptop.
    Somehow I broke my system while installing a new wlan router.
    On boot, with the lan cable connected, my system would pause and display the message to the effect “waiting to configure the network” followed by an other message “waiting an additional 60 second ..” then finally it would boot without internet with the network status icon open ( disconnected ) then after a minute or more it would in fact default connect to the internet by itself. With the lan cable disconnected it would boot normally and the wifi wlan would be connected normally but the network icon still open go figure . Thanks again !!!
