When Linux first <BR> came into the shop, it was as a server only and little thought was <BR> given to needing a graphical user interface (GUI). Recently, the focus <BR> on Linux has been as a workstation or desktop operating system. It's <BR> little wonder &#151; the advantages of Linux over other desktop <BR> offerings in terms of speed, reliability, and cost of ownership are <BR> huge. However, one thing you don't have to think about with other <BR> operating systems is what GUI to use. From a systems administrator's <BR> point of view, choosing a GUI for Linux doesn't mean picking the <BR> prettiest of the lot, but finding a GUI with the features users need <BR> with the lowest cost of ownership. <BR> <BR> With Linux, there are many GUIs to choose from. In this article, I'll <BR> provide a brief overview of the features of the three most popular <BR> GUIs for Linux and try to ease the path through the jungle for sys <BR> admins who until now haven't had to worry about anything other than <BR> Linux's command line interface. Although there are dozens of Linux <BR> GUIs out there, the big three are CDE, KDE, and GNOME. Many of the <BR> GUIs for Linux are window managers only, but these three are complete <BR> desktop environments. Each GUI includes user tools, applications, <BR> network utilities, and development tools. <BR> <BR> CDE, the Common Desktop Environment, has been around the longest. If <BR> you have a UNIX background, you've probably seen CDE before. CDE is a <BR> commercial product that is not free in any sense of the word. CDE is <BR> licensed by the Open Group and was originally designed as a standard <BR> for UNIX desktops under the COSE (Common Open Software Environment) <BR> initiative by Hewlett-Packard, IBM, Novell, and SunSoft. CDE is not as <BR> widely used in the Linux community as the other GUIs. However, if you <BR> are integrating Linux workstations amongst existing UNIX workstations <BR> and wish to keep a standard GUI, CDE might be a good bet. <BR> <BR> KDE, the K Desktop Environment, is an Open Source project that derives <BR> features from CDE, Windows 9x, the MacOS, and also includes some <BR> innovative features of its own. The KDE project began in 1996 and has <BR> made amazing progress. The current version is 1.1.1, and the 2.0 <BR> version is in development. Although KDE is not a commercial product, <BR> it does receive some support from Linux distributors, and it is <BR> undergoing rapid development. At last count, there were several <BR> hundred developers working on KDE, and 110 working on translation <BR> alone! KDE uses the Qt libraries, which were not under an Open Source <BR> license by the strictest definition. KDE is the default GUI for most <BR> Linux distributions and is included with all major distributions. <BR> <BR> GNOME, the newest GUI to the party, is also known as the GNU Network <BR> Object Model Environment. (Free software geeks love recursive <BR> acronyms.) GNOME was created in response to the fact that there were <BR> no completely free desktop environments for Linux and other Open <BR> Source operating systems at the time. GNOME is completely Open Source <BR> &#151; everything included with GNOME is licensed under the General <BR> Public License. GNOME is included with most Linux distributions. <BR> Unlike KDE and CDE, GNOME does not come with a standard window <BR> manager. Instead, GNOME works with "GNOME-aware" window managers like <BR> Enlightenment and Window Maker. <BR> <BR> Cost of Ownership <BR> <BR> Cost of ownership is usually the most important consideration when <BR> choosing hardware, operating systems, or application software &#151; <BR> what is the total cost of ownership? Good administrators won't save <BR> $10 on a network card that is likely to fail and cost $100 in lost <BR> time and labor to replace later, and they haven't gone with Linux on <BR> price alone either. <BR> <BR> Of the three GUIs mentioned above, only CDE requires a license to be <BR> purchased for use. KDE and GNOME are available for free via download <BR> and require no licensing. Of course, cost of ownership goes beyond the <BR> initial purchase price. However, if you're setting up more than three <BR> or four Linux workstations, you can be looking at a hefty fee to equip <BR> each of them with CDE. Xi Graphics' version of CDE, bundled with their <BR> Accelerated X Display Server, has a suggested retail price of $199.95 <BR> for one license. Even with quantity discounts, that can get expensive <BR> fast. <BR> <BR> The other major question of cost of ownership is the stability and <BR> performance of the GUIs. Free software isn't a bargain if it's too <BR> buggy to use. Most of us would prefer to install software once, <BR> configure it, and forget it exists. Having used each of the GUIs for <BR> some time, I've found no stability issues with CDE, KDE, or GNOME. The <BR> 1.0 release of GNOME was somewhat buggy, but GNOME has matured very <BR> quickly. The best scenario would be to install each desktop on a <BR> testbed machine similar to the machines that they will be deployed on <BR> and put them through their paces. <BR> <BR> Features <BR> <BR> Each of the desktop environments include everything a user would <BR> expect with a modern OS. User tools include file managers, calendars, <BR> mail clients, calculators, online help, etc. The one problem with KDE <BR> and GNOME's online help is that it isn't always complete. Several <BR> programs under KDE and GNOME have only partial help files available <BR> for them at this time. The biggest downfall with most Open Source <BR> software is not in the quality of the software, but the availability <BR> of freely available documentation. CDE offers support for English, <BR> German, Spanish, French, and Italian. KDE and GNOME support at least <BR> 30 languages, with more support on the way. <BR> <BR> Each desktop also includes configuration tools for the user to easily <BR> customize the look and feel of their environment. This is a major <BR> improvement for most users compared to the typical window managers <BR> available under Linux, which require customization to be done to text <BR>
