Installed and Available Applications: Compared to the software selection installed by default on other KDE-based distributions, Kubuntu ships with just a handful of applications. As on recently released distributions, LibreOffice has replaced OpenOffice.org as the installed office productivity suite. rekonq is the installed Web browser. Firefox is available for installation. So is Chromium 11, but Opera Web browser is not. Adobe Flash plugin is installed, but because there is no Java Runtime installed, any browser you use will not pass the Java test, OpenJDK Java 6 Runtime, the recommended Java Runtime, is in the repository.
Skype and Miro are available for installation. XBMC, the popular media center application is not in the repository, but Moovida, another media center application, is. Keep in mind that Moovida 2, the latest stable release, is not available for Linux. For your gaming pleasure, Kubuntu developers managed to squeeze in just one game in the default install. Out of the box, the installed video player, Dragon Player 2.0, is unable to play encrypted video DVDs because libdvdcss, the library required to access such video, is not installed. It is also not in the repository. If you need to install Windows applications, Wine, Winetricks and Q4Wine are in the repository.
There are hundreds of packages and meta packages that you can install from the command line or from a user-friendly graphical frontend.
Package Management The easiest method of managing applications on Kubuntu is via the graphical interface to apt-get. This is the main window of the graphical software manager.
The software manager’s settings page. Out of the box, it is configured to check for updates as soon as the system completes booting, and once per day afterwards.
This shows a list of available updates.
Applications listing page on the software manager. For an installed application, a mouseover will show Remove instead of Install.
Another view of applications listing. clicking on an application will reveal more information about it. It is better than the manner that Ubuntu’s Software Center and Linux Mint’s Software Manager lists applications. Unlike those two, this graphical package manager allows you to queue applications for installation.
After installing an application, you are giving the option to run it, but there is no pointer to its location in the menu. The location of some are easy to guess, but it would be nice to have a line in here that points to a newly installed application’s location in the menu.
Graphical Administrative Applications: All graphical administrative tools are accessible from System Settings. It contains a mix of applications that require authentication to run and those that do not. If you have used KDE, you should be familiar with them.
One that I especially like is the “User Management” application. It is just as feature-rich as a similar application on Fedora. You can enable and disable an account.
And configure password aging and expiration. A similar application on Ubuntu 11.04 does not have these features.
