Linux vs. BSD, What's the Difference?by Dru Lavigne
PC-BSD for Ubuntu Users
Ubuntu is known as Linux for Human Beings, because it's driven by the philosophy that "software should be available free of charge, software tools should be usable by people in their local language and despite any disabilities, and people should have the freedom to customize and alter their software in whatever way they see fit" (Ubuntu Documentation).
PC-BSD, on the other hand, "has been designed with the casual computer user in mind. Installing the system is simply a matter of a few clicks and a few minutes for the installation process to finish. Hardware such as video, sound, network, and other devices will be auto-detected and available at the first system startup. Home users will immediately feel comfortable with PC-BSD's desktop interface, with KDE 3.5 running under the hood. Software installation has also been designed to be as painless as possible, simply double-click and software will be installed" (pcbsd.org).
Having used both operating systems extensively, PC-BSD is the one I recommend and the one I install in desktop environments. If you've used Ubuntu before, but haven't tried PC-BSD, give it a try. The increase in responsiveness (i.e., everything seems to just run faster) and ease-of-use will surprise you.
In this article, I'll compare Ubuntu 7.04 (Fiesty Fawn) with the (as of this writing) upcoming release of PC-BSD 1.4.
CD and VmWare images are available from the download page of the PC-BSD web site. As of this writing, the PC-BSD liveCD has not yet been released; it may be available for download by the time you read this article.
To install PC-BSD onto your hard drive, you'll need CD number one. If you wish to install additional software when you install the operating system or need support for one of the 50 native languages, you'll also need CD number two. A list of the supported languages can be found on the PC-BSD Pootle site.
Users who have installed Ubuntu will find that the PC-BSD installer asks similar questions prior to installation. You'll be prompted to select a language, a time zone, a keyboard layout, the hard drive on which to install, and to create a username and password.
You will find some differences. Ubuntu uses sudo to control administrative access, meaning you always use the password associated with your own username, whereas PC-BSD requires you to create a separate password for administrative access. The PC-BSD installer allows you to choose which system components to install; these include KDE components such as games, a software development kit and toys, the FreeBSD ports collection or src, and common applications such as OpenOffice, Firefox, Opera, and k3b (see Figure 1). You'll also be asked to accept a license agreement; while PC-BSD is available under a permissive BSD license, the Intel firmware and Nvidia driver require notification of their licensing terms.

After the install, you'll have the opportunity to change and test your display settings, including the selection of 3D capability if your video card supports it.
I've found that PC-BSD installs much quicker than Ubuntu on the same computer. A clean installation of Ubuntu can take 45 minutes, while a clean installation of PC-BSD can install in 15 minutes.
You can preview the entire installation process along with screenshots and detailed explanations for each step in Chapter 2 of the PC-BSD Quick Guide. Chapter 2 also provides the hardware requirements.
The biggest difference most Ubuntu users will notice is that KDE is used instead of Gnome for the default window manager. The Gnome window manager places its menus in the title bar at the top of your screen whereas the KDE window manager provides a Windows Start Menu-style menu in the lower left corner of the screen as well as a bottom task bar.
At first glance, Kubuntu (the KDE version of Ubuntu) users will notice very little difference in the desktop, other than the PC-BSD splash screen and the four desktop icons. The icons are for Trash (similar to Windows Recycle Bin), a link to the locally installed Quick Guide (highly recommended reading), a link to the PC-BSD web site, and a link to Get Software.
There are three software installation methods available to PC-BSD users, all of which are described in Chapter 4.1 of the Quick Guide.
PBIs (Push Button Installers) are by far the easiest. To install a PBI, click on the Get Software desktop icon while connected to the Internet, then the PBI Directory hyperlink. You can then browse software categorized by Chat, Development, Drivers, Email, Emulators, FTP, Games, Graphics, Look & Feel, Multimedia, Network, Office, Servers, Shells, Themes, Utilities, and Web. You'll also find top 10 lists for the latest software and the most downloaded software, as well as a search utility.
Once you've located an application you wish to install, select a mirror to begin the download of the installation program. When the download is finished, you'll be prompted to enter the administrative password to start the installer. The installer will ask you if you'd like a desktop icon or an entry in the menu and will inform you when the installation is complete. All in all, this method is very quick and painless. This method is also safe because you don't have to worry about dependency issues--PBIs are entirely self-contained programs that do not affect the installation of the operating system or any other application.
If you chose to install an entry in the menu, you'll find a shortcut to your application in the appropriate submenu. For example, Firefox will be placed under Internet and OpenOffice under Office. The arrow pointing to a submenu indicates that that application was installed via a PBI and did not come with the KDE window manager or the operating system. The submenu allows you to run or deinstall the program; some application submenus also provide shortcuts to documentation or extra features.
To uninstall a PBI you can either run the deinstall program from its submenu or use the Add/Remove Software menu. You'll find this menu under Settings -> Software & Updates. After typing in your admininstrative password, you'll see a listing of PBIs under the Installed PBIs tab. You can then highlight a program and click the Remove button to deinstall it. This menu also contains the System Components tab where you can install or remove the system components you saw during the installation of PC-BSD. Note that you will be prompted for CD number two to install software from this tab.
