Hi, I recently installed ubuntu on my dell inspiron 530. I thought it was sweet. so then I wanted to see what Kubuntu was like. then I decided to stick with just normal ubuntu so I ran sudo apt-get remove kubuntu-desktop in ubuntu. but now I can't leave kdm because I wasn't thinking and chose that instead of gdm and I want to get back to gdm. and also I don't have the shutdown or restart buttons when I click the log off icon. I have to log out and then click shutdown on the kdm menu.
