I was playing with the activities and I lost the default desktop shelf. I tried to make a new one, but it was in list format, rather then icon layout. I also found it would not update if I saved something to the desktop.
So how do I get back to the original shelf from install?
Is your old activity not there, when you click on the activity manager (the 3 points in the panel, next to the start menu)?
And what do you mean with “list format”? AFAIK the folderview plasmoid doesn’t support that. Could you maybe post a screenshot? (upload it to SUSE Paste and post a link)
To change the layout of the current activity, you could right-click on the desktop and choose “Settings”.
You may have to add the folderview plasmoid manually though (right-click on the desktop, choose “Add Widgets” and search for “folderview”).
Or quit plasma (“kquitapp plasma-desktop”), delete the plasma configuration file ~/.kde4/share/config/plasma-desktop-appletsrc and restart plasma (“plasma-desktop”). Then you should have back the default layout of a clean install.
