Re: another startx problem

Sure sounds like it. Your KDE client apps need the Qt widget library to run. Try to 'locate libqt.so' in your system. You may have to run 'updatedb' as root to refresh the locate catalog if it hasnt been refreshed lately. If it is just the symlink that has been destroyed and the shared lib exists, you can manually create the link ( libqt.so.2 ) to point to the lib. But otherwise you may have to uninstall and reinstall the Qt libs.
Another suspicious thing: (i normally work with UNIX) in linux, i don't have defined the env variable "DISPLAY". There is no entry fot it.
This variable DISPLAY is usually defined by startx or similar scripts and exported to your X environment. So if you are not in X it is fine if the variable is not defined.
I would suggest using GNOME or a simple WM like twm so that you can get into the X environment and then update your qt libs if you need to using YaST or whatever the SuSE package tool is.
