Is there a distribution using KDE 4 that works?  Although my working 
partition uses Linux From Scratch and Fluxbox, I like testing other 
distros.  I've tried kubuntu and just loaded openSUSE-11.2.  Although 
openSUSE mostly works, KDE has been a (bad word here) disaster.

KDE applications crash and settings I do successfully save revert upon 
reboot.  I don't mean to be overly cynical and my testing hasn't been 
extensive.  So, is anyone having luck with KDE 4.x and a distribution?
