Ubuntu 6.06 Is Current Desktop Linux ChampBy Jason Brooks | Print
Review: The distro's usability and active community earn it high marks; its long-term support will appeal to businesses.Canonical's Ubuntu 6.06 LTS is an excellent Linux-based operating systemso excellent, in fact, that it not only earned eWEEK Labs' Analyst's Choice designation but has also become our clear favorite among Linux desktop distributions.
Click here to read the full review of Ubuntu 6.06 LTS.
This latest Ubuntu release, which became available in June, has won our ardor with a tight focus on desktop usability; an extremely active, helpful and organized user community; and a software installation and management framework that's unsurpassed on any OS platform.
In addition to outperforming Linux rivals as a desktop OS, we found that Ubuntu is a solid choice for server deploymentsprovided, at least, that the sort of graphical management hand-holding that one would expect from Microsoft's Windows Server or from Novell's SUSE Linux Enterprise Server isn't a priority.
Most importantly, for enterprise desktop and server deployments alike, Ubuntu 6.06 LTS is the first iteration of this popular Linux distribution for which the Ubuntu project has pledged so-called Long Term Support (what the "LTS" in the distro's name stands for): three years for the desktop package set and five years for the server variant.
Each of the first three Ubuntu releases shipped with 18 months of security and bugfix updates.
This term of support has been too short for many production settings, despite the alacrity with which Ubuntu handles in-place upgrades.

Ubuntu is free software, periodit doesn't come in separate no-cost hobbyist and per-machine-fee enterprise versions like the Linux distributions from Red Hat and Novell.
Canonical does offer paid support for Ubuntu systems$250 annually for desktop machines, and $750 a year for servers. (See here for more details.)
Ubuntu Linux is available for download, either from an FTP mirror or via Bittorrent, here. The Ubuntu project will mail the distribution on physical media for free, and Amazon.com sells Ubuntu on DVD for $10.
Ubuntu Linux is available in x86, x86-64 and PowerPC versions.
The server variant of Ubuntu is available on all of these platforms, as well as on Sun Microsystems' UltraSparc architecture.
We tested the x86 desktop version on an IBM Thinkpad T41 and an Althon64 system that we built ourselves. We put the server version of Ubuntu through its paces in a VMware virtual machine.
For this review, we did not explore multi-architecture support issuessuch as working around x86-only software when running x86-64 or PowerPC distributionsbut you can expect future coverage from eWEEK Labs in a forthcoming issue and at eweek.com.
On our laptop test machine, hibernation worked without requiring any tweaking, although we ran into trouble when the amount of RAM in play on our test machine exceeded the size of our swap partition. (Our Thinkpad was stacked with 1.5GB of RAM, and the swap partition that Ubuntu created for us during installation was 500MB.)
Also, when putting our laptop to sleep, our machine's hard drive woke up in read-only mode and required a power cycle to bring it back.
Until notebook PC makers begin explicitly supporting Linux on their machines, administrators will have to spend extra time tweaking the particular hardware they support to ensure that everything works properly.
Overall, though, we found hardware configuration tasks in Ubuntu rather straightforward, requiring less fiddling than other Linux distributions we've tested.
However, we were disappointed to see that Ubuntu still lacks a graphical utility for configuring display settings beyond simply choosing among available display resolutions.
Ubuntu did a fine job of auto-configuring our test machines' displays, but further customizations required hand-editing. For instance, to configure our Thinkpad to use multiple monitors, we had to manually edit the xorg.conf file. We'd like to see Ubuntu begin shipping Red Hat's display configuration toolnot only would Red Hat's tool fit in well with the rest of Ubuntu's configuration utilities, but it is open source and available for the taking.

Since Linux distributions boil down to collections of software that are freely available to everyone, distributions most clearly differentiate themselves from each other in the ways that they bring together and manage this software.
Ubuntu owes its excellent software management framework to Debian GNU/Linux, the venerable distribution from which Ubuntu is derived.
In addition to the command-line dpkg and apt utilities that form the foundation of Debian's and Ubuntu's software management schemes, Ubuntu ships with four other front ends for installing and updating software: one for installing single packages, such as those downloaded from a Web page; a very simple Add/Remove Programs interface for browsing through and installing applications available in the system's configured software repositories; a more complex tool, Synaptic, for managing packages; and an updater daemon that runs in the background and prompts users when updates are available.
All of these interfaces front the same software mechanism, and all handle software dependencies automatically.
Ubuntu's software management system supports package signingwe could opt to accept installation only of packages for which we'd previously imported a signing key.
We also could configure our system to install security fixes automatically, which is an important feature for managed desktop scenarios, where users are not allowed to install software or updates on their own.
Just as important as Ubuntu's proficiency in easing package installation and updates is its effective structure for providing access to third-party applications, both open source and proprietary.
During tests, we were able to install VMware's VMware Player, Sun's JRE, Abobe's Flash player and Acrobat Reader, the Opera Web Browser and a handful of other proprietary applications just as easily as any other Ubuntu component.
In addition to these applications, which we installed from official Ubuntu repositories, the project benefits from an array of volunteer-run repository projects.
While other popular distributions, such as Fedora and OpenSUSE, also benefit from volunteer, third-party packaging, the Ubuntu community appears to doing a better job keeping itself organized.
Part of the reason for this is that the Debian project through which Ubuntu can trace its heritage is much more focused on organizing and enabling volunteer packaging efforts than are other Linux distributionsmost notably, those of Red Hat.
We were impressed to find included among the very good documentation that ships with Ubuntu a software packaging guide.
When a precompiled package is available for your Linux distribution, software installation and update is easier than on any other OS platform.
The Ubuntu project appears to understand this, and the fruits of the project's outreach include community-contributed gems such as EasyUbuntu, a simple application that automates a handful of common operations that often vex desktop Linux users.
More evidence of Ubuntu's smart community outreach can be found in the Kubuntu and Xubuntu distribution variantstwo community-spurred but Ubuntu-embraced distribution variants that replace the system's default GNOME desktop environment and application set with KDE and XFCE flavors, thereby neatly broadening the distribution's appeal.
We found Ubuntu's default GNOME 2.14.2 desktop environment complete and easy to use.
Peripherals such as USB memory sticks, digital cameras, scanners and printers worked as we expected.
Palm and Pocket PC synchronization remain an area of trickiness and require tweaking on the Linux desktopwe were able to link up with a Palm Treo device, but we ran into trouble synchronizing.
Neither the Beagle search tool, which brings Google Desktop-style search to Linux, nor the NetworkManager framework, which makes switching among wired and wireless connections very easy, were installed by default on our Ubuntu test systems.
However, we could install both of these applications from the Ubuntu repositories, and both functioned for us without a hitch.
Along similar lines, we had the option of installing the Xgl 3D desktop effects applications we last tested in OpenSUSE 10.1, although, in our opinion, Xgl is currently a bit too flaky for daily use.
