I am running Ubuntu 12.04 and decided to try Kubuntu desktop. I didn't like so tried to remove it but it has left a lot of KDE appliances still on the machine . I used 'aptitude' to install and aptitude to remove it . Although it now says that Kubuntu is no longer installed there are plenty of stuff left over . For instance the Startup screen, and desktop will not go back to the original ubuntu screen . It seems to be very screwed up . I have tried what others have said in the forums but aptitude does not work fro me in removing kubuntu .
