Problem with Network Manager GUI on LXQt environment (Lubuntu 20.04 LTS and Lubuntu 21.04)

[Piotr]

Dear Community,

I have problem with Network Manager GUI. On Lubuntu 20.04 LTS and Lubuntu 21.04 when I click left mouse button on the icon of network manager this didn't work and window is not showed. Only right click of the mouse is working on this icon. I don't know if it problem with LXQt or with all Desktop Environments on focal. I checked and on Fedora 34 Spins this works normally and like we knot this disto also use LXQt so I think that this is not problem with LXQt itself. Can you fix it?

My distro: Lubuntu 20.04.2 LTS (without updates, clear iso downloaded from ubuntu mirror and booted for testing)

P.S. I can't report bug with apport because my wi-fi didn't work on live session because I can't remember my password.

Yours faithfully,
Piotr

Thank you for taking the time to report this bug and helping to make Ubuntu better

I tested for this on hirsute (21.04)
- hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
(a QA-test install with almost no changes; only those required to confirm valid QA install & working system)

Also use current impish live (QA-test)
- sony vaio svp112a1cw (i5-9400u, 4gb, intel haswell-ULT)
- dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)
(the sony has wifi only, dell has ethernet only)

and could not re-create this. I also don't recall seeing it either on any of the boxes I QA-test with sorry (on focal thru hirsute cycles which is over hundreds of tests)

I suspect the issue is specific to your hardware, thus apport-collect is required. I realize you said you cannot apport-collect currently, but I can't see how this can be worked on given the current lack of networking hardware detail provided.

Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1927831

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Further to prior comment, I also performed a QA-test using focal daily (20.04.3) on
- sony vaio svp112a1cw (i5-9400u, 4gb, intel haswell-ULT)

and didn't have any issues with regard this bug.

@Chris Guiver it is not nm-tray. I prefer network-manager-gnome and I used it. I also not installed Lubuntu. I used live session for testing (booted from USB and not installed OS to hard drive).

Network Manager works but like I said if I click left button of the mouse this result no action. Only click of the right button works. I think that you checked nm-tray instead GNOME Network Manager.

Chris Guiver, do you will check this issue? You wrote: "Further to prior comment, I also performed a QA-test using focal daily (20.04.3) on

I think that you didn't test it properly. You probably used nm-tray and this is no issue. I said that I used GNOME Network Manager (GUI nm-applet? This same like was for Lubuntu 18.04.5). You had installed it on Lubuntu 20.04.2 I only changed austostart configuration and turn off nm-tray and turn on Network Manager GUI (GTK3 nm-applet probably).
