I'm using opensuse11.0 and Gnome 2.22 currently and tried to switch to KDE4. I have installed KDE4 desktop from Software.openSUSE.org (1-click install), but don't know how to start KDE, tried rebooting, typeing "kde" or "kde4" in a terminal window. none helps. Is there any thing I need to do to get KDE4 running or I have to reinstall the OS?
