Bug description:
The average user cannot tell when they are installing a desktop
environment as a dependency of a package.
Having various desktop environments can reduce system performance
sensibly, as processes from various desktops are running
simultaneously in the background. Moreover the autoremove tool cannot
always identify the dependencies when removing some of those installed
packages.
For example if I install the "cortina" package, it takes with it the
GNOME Display Manager and plenty of wallpapers. Then if I uninstall it
and do "sudo apt-get autoremove" those packages are not detected as
unused.
Another example: if I install the "rkward" package plenty of KDE
services, like the Akonadi indexing service, are installed. Then
launching applications in my Inter Core 2 Quad becomes noticeably
slower, because my system is running both GNOME and KDE services
simultaneously.
If I remove rkward and then I perform an autoremove, the system still
stays slow. If I uninstall all the packages in the universe
repository, perform an autoremove, and then reinstall the applications
I had, the system becomes fast again.
The user shall know these potential problems beforehand.
