I downloaded a Debian wheezy netinstall iso file, and just made a very minimal installation with no Display manager or desktop environment.
I was using the terminal for testing purpose. I later installed cinnamon from Linux Mint backport repos. It worked fine.
Then, to have a display manager, I choose to install lightdm. I used the command
sudo apt-get install lightdm
The installation was successful, but when I restarted, Gnome 3 was also installed. How do I remove gnome3 and all its dependencies without affecting the system ?
