This may not be kdebase; but it is some KDE package. I start up X using KDE, which starts up fine. But switching back to the virtual console from which I started X I see this: undecodable token: \1b[> undecodable token: \1b[> kwm: X_ConfigureWindow(0x1c00097): BadMatch (invalid parameter attributes) kwm: X_ConfigureWindow(0x340000d): BadMatch (invalid parameter attributes) I don't know if this is a symptom of some deeper problem or not. # rpm -qa | grep kde switchdesk-kde-1.7.1-1 kdebase-lowcolor-icons-1.1.2-7 kdegames-1.1.2-1 kdegraphics-1.1.2-1 kdelibs-1.1.2-6 kdesupport-1.1.2-2 kdetoys-1.1.2-1 kdeutils-1.1.2-1 kdeadmin-1.1.2-1 kdebase-1.1.2-7 kdelibs-devel-1.1.2-6 kdemultimedia-1.1.2-1 kdenetwork-1.1.2-3
we can't tell what's wrong from this amount of info. Does this output appear IMMEDIATELY after starting KDE? You haven't run any other programs following that?
I can't see those on any reasonably recent version of KDE, assuming it's fixed.
