I’ve been experimenting. First I installed openSUSE 11.1 Gnome desktop. It went well. Then I used Yast Software Management → Patterns → to add the KDE4 desktop. But I can’t figure out how to start KDE4 instead of Gnome when I boot the computer. I’m used to having a choice on the login page via a link low on the page. But that doesn’t present now. So how do I get into KDE instead of Gnome?
