Disappearing Panel in KDE 4

KDE 4.0 is still buggy. Plasma crashes a lot and quite surprisingly the applications panel disappears. No worries, let me show you how to bring the panel back.

1. First, kill/close the plasma process. One easy way is to cntrl + escape, search for plasma and kill it.

2. Your desktop disappears. Press Alt + F2, to bring in the kicker and launch the terminal.

3. Delete the plasma configuration file and relaunch plasma
rm ~/.kde4/share/config/plasma*

2. Voila!! Panel is back.
Sad part is you need to reconfigure your desktop, icons and widgets.

PS: Do read the Emergency release notes FAQ and the KDE 4 visual guide
