All is working fine with the exception of the taskbar network icon (bottom right of the screen). This shows a picture of a screen with a red cross in the right hand corner. The actual netork connection is wired and working fine. I am assuming that this is a hangover from the previous network connector but how do I correct it?
I’m only surprised that you didn’t realise it was set that way. (You mentioned that you had upgraded to KDE 4.13, and that would not have changed the setting by itself , so you must have been using ‘ifup’ previously.)
That’s why it is important to supply the complete output when given commands to execute. It would have been obvious from the first part of the output that the service was disabled.
I’ve been using network manager with KDE plasmoid (without issue) for a number of years now, but I have to connect to number of different networks and configure network equipment as part of my job. If you’re only using NM to connect to a single network, you’re better off sticking with ‘Traditional ifup’ IMHO.
What exactly do you mean with “worked fine”?
The network management icon absolutely needs NetworkManager to provide any function, as it is just a frontend to NetworkManager.
Maybe it just didn’t show the red cross in 4.12.4?
In fact I tried to switch to ifup now on my KDE 4.12.4 system, and it does show just a red cross there as well. But the icon is hidden so you only see it if you click on the small up-arrow in the system tray just left of the digital clock.
AFAIK KDE 4.13 contains the new plasma-nm, maybe this does not hide itself when NetworkManager is not running?
Or maybe it was set to “Always show” in your case, I’m not sure of the defaults in 4.13 as I haven’t installed it yet.
Btw, for just a wired connection you don’t really have a need for NetworkManager. And the network did work as you wrote.
If you’re just bothered by that red cross when using ifup, you can disable the networkmanagement plasmoid in the “System Tray Settings”.
Due to the well-documented past problems with kde network manager - ifup was the recommended option.
What well-documented problems?
I never had any problem at all with KDE4’s networkmanagement plasmoid.
Right-click on the small up arrow (that would show the hidden icons) just left of the digital clock and choose “System Tray Settings”.
On the “Display” tab you can completely disable the networkmanagement applet, on the “Entries” tab you can set the visibility of any of the tray icons to “Auto”,“Always Shown” or “Hidden”.
