Recently after recompiling my KDE build, I was exploring what has changed in the few weeks when my notebook wasn't with me. Marco is really working hard on the netbook shell and I thought to give it a try. Man, it looks superb and I like that on my notebook 🙂
Anyway, I switched back to the regular Plasma desktop and after I logged back in, plasma-desktop refused to start automatically. I tried removing my .kde, but no luck.
After some help on IRC, I found the problem. Netbook shell was added to .config/autostart directory and the configuration wasn't removed after switching back to Plasma Desktop shell. So, the easiest fix is to simply delete the plasma-desktop and plasma-netbook entries from .config/autostart . WORKSFORME 🙂
