Wifi icon in the top bar gets replaced with a wired connection icon after disconnecting

Support and Help
1

I installed Ubuntu 24.04 on my new laptop recently. (Dell 15 with AMD Ryzen 3 7320U). I am using Gnome Classic.

Things were fine. Today I installed KVM, created a VM in it and used it for some time. After that I shutdown the VM and closed virt-manager. Then I disconnected my laptop from the wifi network. Usually the wifi icon should disappear from the top bar. In this case too it did but the wired connection icon gets displayed in its place. If I reconnect to a wifi network then the wifi icon comes back. No wired connection icon. When I disconnect, the wired connection icon comes back. If I logout and log back in, the wired connection icon is not shown.

The wired connection icon is something like this : https://help.ubuntu.com/stable/ubuntu-help/figures/topbar-network-wired.svg.

Why should the wifi icon be replaced with the wired connection icon, even when there is no connection of any kind? Why should this occur after I installed a VM?

Thanks

Isn’t that just network manager so you can configure the network if required?

How do you have networking set up for the specific VM you were running?

While you have this seemingly-incongruous wired connection icon showing, please run the following command in Terminal, for post its output here:

nmcli dev status

@Actionparsnip I don’t know how the Network Manager icon looks like in the top bar but this one is for indicating wired connection. Note that it is not always shown in the top bar and goes away when I re-login.

@halogen2 I did not make any changes to the network setting while installing the VM. I used whatever was the default. Inside the VM also I use Gnome Classic. The top bar in the VM always shows the wired connection icon in it, treating the network connection as a wired one.

Here is the nmcli output

Before connecting to wifi

$ nmcli dev status
DEVICE  TYPE      STATE                   CONNECTION 
lo      loopback  connected (externally)  lo         
virbr0  bridge    connected (externally)  virbr0     
wlp2s0  wifi      unavailable             --         
$

After connecting to wifi

$ nmcli dev status
DEVICE  TYPE      STATE                   CONNECTION 
wlp2s0  wifi      connected               DRSD-5G    
lo      loopback  connected (externally)  lo         
virbr0  bridge    connected (externally)  virbr0     
$

After disconnecting from wifi

$ nmcli dev status
DEVICE  TYPE      STATE                   CONNECTION 
lo      loopback  connected (externally)  lo         
virbr0  bridge    connected (externally)  virbr0     
wlp2s0  wifi      unavailable             --         
$

Inside the VM, nmcli shows :

$ nmcli dev status
DEVICE  TYPE      STATE                   CONNECTION 
enp1s0  ethernet  connected               enp1s0     
lo      loopback  connected (externally)  lo

Providing the output from the following command would clarify the context:

inxi -SNxxx

Icon that I located,

  • network-offline-symbolic_mine

was found at (depending on your theme selection),

  • /usr/share/icons/Yaru/scalable/status/network-offline-symbolic.svg

I am using the default theme (Adwaita) and it has

/usr/share/icons/Adwaita/symbolic/status/network-offline-symbolic.svg

This icon is different from what you referred to. Two arrows, one facing right, the other facing left and a x at the end of the second arrow.

I don’t think I have ever seen a network-offline symbol in the top bar. If not connected, nothing will be displayed.

Thanks

Indeed, when I turn off my WiFi, I get that same icon. No VM involved.

EDIT: The following comment is incorrect.
@karthikeyan.d I believe that showing the icon is the correct behaviour, so not seeing the icon seems to be the oddity.

@paddylandau Interesting. If you log out and re-login, is the icon still there in the top bar?

When you see the three-boxes icon after disconnecting from your wifi, do all the boxes have the same colour and no x on any of them? If yes, then it represents a successful wired connection, not a disconnected state for which the icon will have an x over the bottom-right box and the other two will be coloured. See the icons in the section “Wired connections” in

https://help.ubuntu.com/stable/ubuntu-help/status-icons.html.hi

Are you using Gnome Classic? What theme do you use?

Thanks

I disabled WiFi and restarted the computer, and the icon wasn’t there after restarting.

Plain white:
Network icon

Oh, I see, you’re right! Yes, I can see that it does indeed look like a bug. My apologies for my earlier comment, which is wrong.

I’m using standard Ubuntu 24.04 (upgraded from 22.04) with the default GNOME, and using X11 instead of Wayland.

Since I did not see this before 02/Nov, I checked /var/log/apt/history.log to see what all were installed on that day. I had installed KVM packages and virt-manager. There were four unattended-upgrade runs :

  • libssh-*
  • libctf*, binutils-* etc (GNU stuff)
  • xserver-xorg-*
  • xwayland

I use GNOME Classic which uses Wayland. So I logged out and selected GNOME Classic with Xorg. No change in behaviour. There were two other options : Ubuntu and Ubuntu with Xorg. Tried them too. No change.

11

I was able to reproduce the issue on another laptop. It starts occurring immediately after installing the KVM packages.

The second laptop has Intel processors with Ubuntu 24.04. It did not have KVM.

I had not updated the system after 31/Oct. So I first did a sudo apt upgrade, to see if the problem occurs without KVM. It did not.

This system did not have GNOME Classic. I was using the default session (Ubuntu/Wayland). I installed gnome-shell-extensions and switched to GNOME Classic. Still the problem did not happen.

I stayed in GNOME Classic.

For KVM installation I used the instructions from here.

The steps that I did were

1. sudo apt install cpu-checker
2. sudo kvm-ok
3. sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils -y
4. sudo adduser [username] libvirt
5. sudo adduser [username] kvm
6. sudo apt install virt-manager -y

After each step I disconnected from wifi to see what happens. Immediately after step 3 the problem occurred : on disconnecting from wifi, the wifi icon disappears but the wired connection icon is shown in the top bar.

52 packages were installed in the third step. I am looking at their names. So far there seems to be nothing related to UI.

At the end of the installation I see

Processing triggers for hicolor-icon-theme (0.17-2) ...                         
Processing triggers for gnome-menus (3.36.0-1.1ubuntu3) ...

These two are not part of the list of 52 packages installed. They are the only ones related to UI.

Here is the full output of step 3 :

$ sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils -y

I have none of those packages installed. But, I did use KVM some time ago, so presumably (I don’t remember now) I would have installed them back then, and subsequently uninstalled them.

So, I tried this by booting into a Live USB (Ubuntu 24.04.3) and installing the packages as you did. I split them up, to narrow it down further:

sudo apt install cpu-checker
sudo kvm-ok
sudo apt install qemu-kvm
sudo apt install libvirt-clients
sudo apt install libvirt-daemon-system

It was after the last one, libvirt-daemon-system, when the problem started. This means that we now know:

  • It has nothing to do with processing triggers for hicolor-icon-theme or gnome-menus, because these were done when installing qemu-kvm, and the problem didn’t occur after that step.
  • The problem is caused specifically by installing libvirt-daemon-system.
  • The problem is reliably repeatable even on a Live USB.

You might want to report this as a bug on Launchpad. If you do so, please post the link here so that I can upvote it.

I was thinking of doing this by uninstalling all the KVM packages on my system and installing them one by one. Thanks for doing it.

It was after the last one, libvirt-daemon-system, when the problem started.

Looks like this pkg contains config files to run the libvirt-daemon as a system service. Somehow it is interfering with the icons.

You might want to report this as a bug on Launchpad. If you do so, please post the link here so that I can upvote it.

Will do. I’ve never filed a bug on Ubuntu before. Will take a look.

Thanks
