KDE does not work after upgrade + hang to 9.1

[Jochen Wurster]

Hi all,

i have upgraded my machine from Kubuntu 9.04 to 9.1. The update ran 
without any error. After the update the reboot dialog appeared. 
Unfortunately my machine hanged at this moment. So i had to do a hard 
reboot. After the reboot it is no longer possible to login into kde. The 
login dialog appears. After the login only the background image is shown.

I think the update is not complete (because of the hard reboot). Do you 
have an ideas on how to complete the update.


Bye Jochen
