I did have such effect as KDE bar disappearing after I twicked my desktop … I had to remove the .kde4 directory from my home dir and re-login. And I had a blank KDE desktop functioning again …
With my regular user, not root though.
This being said, I did a clean install on my problematic upgraded 11.0 to 11.1 and all went well. I had to reinstall all my rpms again but at leat all is working. EXCEPT the booting process ! I still have to boot with the DVD in otherwise GRUB stays stuck at stage 2. That makes me furious… I created a post just for this one.
I have no issues after upgrading 11.0 to 11.1 on my second laptop, everything works fine. All I had to do is (re)install softwares that were not added from the main opensuse repos (amsn, skype, vmware, etc), as those were uninstalled during the upgrade.
I had a problem in that ldap wasn’t upgraded and I couldn’t use ldap logins. Since I thought there could be are other problems I hadn’t discovered, I then did a fresh install and everything works fine. Since I have a separate /home this wasn’t a problem for me.
