KDE freezes after installation

Hi all,

I installed openSuse 11.1 64-bit with Gnome : everything works fine.

Because I wanted to be able to have more functionality I decided to re-install and to take KDE instead. Installation : OK, but when I come to the desktop screen, the only thing I can do is CTRL-ALT-DEL and switch back to Windows. The mouse pointer looks a bit odd (I have a USB scroll mouse) and I can’t move it. The arrow keys nor TAB nor SPACE work either.

Anyone a clue ?

Thanks for your answer,

W
