Once you have Ubuntu installed, you can install KDE desktop by doing:
Code:sudo aptitude install kubuntu-desktop
It's quite a big download.
Then, in your login manager, you have a "sessions" option that you can use to change between Gnome and KDE at login
I must say even though KDE4 still needs work I have no regrets so far, the only issues I've had is that it does not include samba and disk&filesystems preference panes which KDE3 had but I'm happy regardless.
Now to take on Samba using the brute force method![]()
