I wanted a window manager, so I installed xfce4. I used
sudo apt-get install xfce4
to do this. To remove it, I used
sudo apt-get remove --purge xfce4
which didn't work, and neither did
sudo dpkg purge xfce4
as evidenced 1)
startx launches the xfce desktop, and 2)
apt-cache search xfce4 returns a long list of installed packages.
So, how can I get rid of xfce4 and it's dependencies?
