If you rename ~/.kde you do not need to reinstall kde.  It will automatically 
be re-created by restarting your login.

I think this is a misunderstanding.  Other desktops/window managers are not 
using the same parts of the X driver - there are parts that have been 
virtually untested until now.  This is new ground.  However, there are 
workarounds for most hardware situations that should get you sorted.  I would 
have thought that the *buntu lists were your best bet, otherwise it's just 
google to find a case most similar to yours, I'm afraid.
