Yesterday (21 Oct 2014) my development machine said it had to be restarted due to an update. After rebooting and logging in I got no desktop manager. There happened to be an open konsole.
After trying a bunch of things I started muon and found that my KDE workspace is broken.
The problem is that I can't start the networking as I cant get to the network manager applet. Then I hit Ctrl-Alt-F2 and open a command line session and found that ifup doesn't work due to networkmanager settings. But I can't find the config files.
So how do I start the network from the commandline? What are the commands to get the KDE workspace package re-installed?
