My new computer is pre-installed with suse 11.2 but with the gnome desktop. I have tried to change it , via yast , to the kde desktop and duly changed the default to kde. This had no effect however so I went back to yast and installed some kde4 packages which it seemed may be necessary. Still no result but now the 'start button' computer icon is missing from the desktop lower left corner and I am unable to launch applications in the normal way.I would appreciate any suggestions as to how I can return the machine to normality, preferably with the kde desktop.
