Package: apt Version: 10.0.10.2 Severity: normal Tags: upstream As reported in (https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1528028).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.
