Like every good graphical package manager should, when you install one or more packages, GNOME PackageKit will give you an option to run the application, and also point to its location in the menu.

And there are many more software repositories enabled out of the box than are available on Fedora. Many are, of course, non-free sources, so unless there is a major philosophical shift in Fedoraland, you will not see them on a default installation of Fedora.

The update manager works just fine, and it will check for updates soon after the system boots.

A problem you will most certainly encounter when updating or installing applications is illustrated in the next three images: In the first image, the system is requesting confirmation before it can install an application during an update. It was probably needed to satisfy a dependency. By why is it requesting input from the user before it can install a required application?

It just happens that it is attempting to install an application from an untrusted source, so it wants you to authenticate first. It also informs you that you should not install it unless “it is safe to do so.” But how is a lay user supposed to know whether a source should be trusted or not?

Giving the user a bit more information about the package does not really help very much. The point I am trying to make here is that the sources enabled by default on any distribution should be verified as trusted by the developers before it is made available to the public.

Installed and Installable Applications: Fusions ships with enough applications to satisfy the desktop computing needs of most users. Here is a listing of the major applications installed by default:

  • Chromium browser (version 11)
  • Miro Internet TV
  • OpenOffice.org 3.xx
  • Empathy IM Client
  • The GIMP, a Photoshop-like application
  • Scribus, a desktop publishing application
  • Inkscape, a vector graphics editor
  • VLC
  • Totem movie player
  • GNOME MPlayer
  • Handbrake, a multithreaded video transcoder with support for Apple TV
  • Dropbox
  • Wine – a program which lets you run Windows software on Linux and other operating systems

Aside from the above, educational applications, like Marble and Stellarium, a real-time nightsky viewer, are also installed. While Fusion packs a lot more applications than Fedora, a few unnecessarily duplicate the functions of another. For example, what is the need for Totem, when VLC is installed, or for GNOME MPlayer, when Banshee is the default audio player. But that is just a minor issue.

A few classic GNOME applications were replaced with more feature-rich ones. For example, Shutter, a screenshot application with many features not available in other screenshot applications, is installed in place of the classic GNOME screenshot application. Chromium is the installed default browser instead of Firefox, and K3B, the CD/DVD/VCD burning application for the K Desktop Environment (KDE) is installed in lieu of Brasero.

In terms of games, all the classic games you will find on a standard GNOME desktop distribution have been replaced with about a dozen space-shooter and arcade-shooter-type games. In addition PlayOnLinux, a program that makes it easy to install and run games designed for Microsoft Windows, is installed.
