I have downloaded KDE with the following command from terminal:
sudo aptitude install kubuntu-desktop
After this, it took about 2 hours to download it. Now, my problem is I think it was not installed or I have to go to some configuration file because i got this message at the end of the command:
I think it is installed right? Now, the thing is the KDE does not appear in choose sessions. What should an ultimate newbie do to make it work? From configuration up to the point it appears in the choose session menu. Thanks!
