    [SOLVED] Cannot start KNetworkManager

    Hi,

    I cannot start the KNetworkManager GUI. I can see the process is running, but that's about it.

    I tried starting the GUI by
    1. issuing the 'knetworkmanager' command in a console window,
    2. issuing 'knetworkmanager' in 'run command',
    3. selecting the manager via the start menu.
    Nothing works.

    Right-clicking the item in the start menu and selecting 'Edit Item', I marked the option 'Place in system tray' and then after a restart the KNetworkManager icon briefly flashes and disappears from the system tray.

    Some data:
    laptop: Compaq Presario A970ed laptop
    OS: Kubuntu 8.04.1 desktop amd64
    Wifi-adapter: Atheros AR5007 (getting that to work is the next challenge)

    How can I start the GUI? I am not a networking specialist, so I want to avoid a complete manual command-line configuration.

    Any help is greatly appreciated!

    Re: Cannot start KNetworkManager

    Psycko, Is there an icon for the knetworkmanager in your system tray near the clock?

      Boot and start KDE and run the following command:

      ps aux|grep knetworkmanager

      If you get two lines knetworkmanager is running already, if you only get one line then start it using one of the methods you suggested and try the command again. Do you get two lines now?

        Re: Cannot start KNetworkManager

        Tinker, when I log on I see the KNetworkManager icon in the system tray for about five seconds, and then it auto-disappears.

        Toad, the knetworkmanager process is running from the start: after logon and running your suggested command, I get two lines: one for the command 'knetworkmanager [kdeinit]', and the other for the command 'grep knetworkmanager'. Trying to start the GUI and running the ps command again yields the same two commands.

        There is however a peculiarity: now that I look at the results of 'ps' a bit better, I see that the process state is 'S', which according to the man page means 'Uninterruptible sleep (waiting for an event to complete)'. So, it looks like the process initialisation did not work out well.

        I did a fresh re-install from CD a few days ago, and only installed some software from the repositories. Nothing else. So, the startup of KDE and knetworkmanager is that of a new install. Any ideas on how to find out what event it is waiting for?

          Here is my output:

          ingo@debtop:~$ ps aux|grep knetworkmanager
          ingo 6735 0.1 0.5 34696 5372 ? S 19:16 0:07 knetworkmanager [kdeinit]
          ingo 12347 0.0 0.0 3008 772 pts/1 S+ 20:30 0:00 grep knetworkmanager
          So I got the S as well

          I am surprised that your icon is there for a couple of seconds before disappearing...

          Can you post the output of ifconfig to see what your interfaces are doing?

            Knetworkmanager working properly (as it has been from the very begining).

              So, the problem is at least not that it is waiting for an event.

              I did an ifconfig twice: once with the ethernet cable connected and once unconnected. In both cases the icon quickly disappears from the system tray (actually, sometimes the icons appears for a split second or it does not appear at all), in both cases the KNetworkManager GUI does not show up when I try to start it, and in both cases the process knetworkmanager is running.

                No packet errors are being reported:
                RX packets:355 errors:0 dropped:0 overruns:0 frame:0
                TX packets:416 errors:0 dropped:0 overruns:0 carrier:0
                The numbers 355 and 416 are the number of RX and TX packets. Errors, dropped, overruns, and frame are all reported as zero ( 0 ).

                  Re: Cannot start KNetworkManager

                  Hi,

                  It looks like KNetworkManager was available all the time in the system tray.

                  The icon I see in the start menu is a green globe, and that is also the icon I see briefly in the system tray. Therefore I assumed that that green globe should stay in the tray to give access to the settings for knetworkmanager. However, there is another icon that looks like a cable plug and now I see that that icon gives access to knetworkmanager. The two icons can be seen simultaneously in the tray for a few seconds after logon. That confused me.

                  Thank you for your help and sorry for any inconvenience.

                  Now I will see if I can get the wireless network to work ...

                    Ahh! Yes, the white system tray icon is the knetworkmanager icon. The green globe you are seeing is adept doing its thing to see if any updates are available.

                      Ha! That is funny

                      Your ifconfig data shows both as being connected as well
