For example I can type dolphin in the terminal, and my session starts up with my fav apps, but I have no KDE start menu and no bar down th ebottom of my screen, I can alt-tab through open apps. alt- F2 gives me the command line widget but nought works there...
I've got muon package manager running (I assume it's some failure in installing or configuration) but it's saying there's nought to upgrade.
what do I do to isolate the issue?
And in trying to get kmenuedit going from the terminal and I get the following:
