Network manager applet displays the unmanaged wired interfaces

[artem-sidorenko]

Observed behavior: NM applet of cinnamon displays the unmanaged interfaces, see screenshot below

Output of nmcli:

$ nmcli d

Expected behavior: NM applet of cinnamon should not display the unmanaged interfaces

Same for running a docker-compose project with many services: the list of wired connections gets longer than the screen height due to a multitude of unmanaged interfaces shown. The only managed wired interface is off-screen and cannot be reached, so I would even consider this a bug.

Same issue here, results in my wireless connections being pushed off the bottom of the screen

[josevavia]

Any update on this? It is especially annoying with big docker-compose projects like willydee said

Cinnamon 3.6.7 on Ubuntu 16.04 here, I got this issue too. My ethernet connections' list is so long it doesn't fit on the screen and I don't see on/off control. Any chances for newer version for Xenial?

Unbelievable how this is still an issue in most linux distros.
With the advent of docker driven development environments this is a very serious usability issue (see screenshot) and yet nothing has been done in >3 years.

How hard can it be to, for example, add a new option to NetworkManager.conf similar to unmanaged-devices enabling the user to exclude interfaces from nm-applet?

Still experiencing it on Ubuntu 18.04.

There is a Gnome shell extension that supposedly solves this. Anybody know if/how to install this with Cinnamon or MATE? https://github.com/linniksa/nm-hide-unmanaged-gnome-shell-extension

[jaszhix]

This should be fixed on master.

For those interested, there's an easy fix for the cinnamon network applet that I also shared in the ubuntu bug report: 3e366ce

Today I've updated to Cinnamon 4.0 using this tutorial, BUT I DON'T RECOMMEND IT. Cinnamon was unstable, some applets were not loaded, I ended up with purging apt repository, went back to Cinnamon 3.6, had to log in using Gnome, enable embrosyn PPA and update to 3.8 again..... 🙄 And everything because I didn't see @nocive's comment.

[Wirone]

I confirm, fix from @nocive's comment works like w charm! (requires restarting user session)

THANKS!

[mtwebster]

@Wirone I can guarantee you this change was not the cause of your issues.

That fix is also flawed, there is a better fix in the latest cinnamon release (4.0.2)

If a particular issue here is not fixed in 4.0.2, please open a new issue.

[Wirone]

@mtwebster - I've added new PPA and updated Cinnamon with dependencies. Nothing more, so most probably it caused my problems.

After upgrading to 4.0 I had issue with restarting computer ("failed deactivating swap" for >10 minutes, then freezed), after restart system was working on Kubuntu and Ubuntu (not Unity). On Cinnamon I didn't have "Start" applet (windows-like), I couldn't launch some applications including software & updates, I had to purge PPA from CLI but it restored Cinnamon to 3.6 which wasn't working at all (couldn't log in, had to update from regular Ubuntu).

I'll wait for 4.0 from embrosyn...

@Wirone you're most welcome! And thank you as well for your comment, it's gratifying to know I was able to help someone else with the same problem as mine. Cheers!

[nocive]

@mtwebster it may very well be flawed but it's a very pragmatic and easy fix that anyone can easily apply as opposed to, you know, updating your entire system (and potentially break it) for the sake of fixing one desktop applet.
