For reasons I do not really know about, the bar with the Suse Menu button at the bottom of the screen, whatever it is called in English, does not appear anymore when I login.

Of course, I can press Alt-F2 and type kicker, and yo! it's there again

Is there however a way to make that automatic ?

Also, while the command kicker is recognized under Alt-F2, I have trouble understanding why typing which kicker from a terminal (konsole, for instance) does not yield any result
