@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. ** Also affects: network-manager-applet (Ubuntu) Importance: Undecided Status: New ** No longer affects: nm-tray (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927831 Title: Problem with Network Manager GUI on LXQt environment (Lubuntu 20.04 LTS and Lubuntu 21.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1927831/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
