The Top 7 Best Linux Distributions for You


There are various approaches to answering this question. The broad answer is: "any of them," but that's not very helpful if you're just looking for a place to start.
The problem is, there never can be one best Linux distribution for everyone, because the needs of each user tend to be unique. Telling someone who's looking for a good introductory distribution to try Gentoo, for instance, would be a mistake because for all its positive qualities, Gentoo is decidedly not a beginner's distro.
All too often, Linux aficionados will tend to list the distributions they like as the best, which is fair, but if they are not aware of their audience, they could suggest something that does not meet that person's needs. Finding a good Linux distribution is like finding a good match in an online dating service: good looks aren't the only quality upon which to judge a Linux distro.
To help users discover the Linux distribution that's best for them, this resource will definitively list the best candidates for the various types of Linux users to try. The use-case categories will be:
  • Best Desktop Distribution
  • Best Laptop Distribution
  • Best Enterprise Desktop
  • Best Enterprise Server
  • Best LiveCD
  • Best Security-Enhanced Distribution
  • Best Multimedia Distribution
Once you find the best Linux distribution for your needs, you can visit our Linux Migration Guides to assist you in installing and using the one you'd like to try.

Best Linux Desktop Distribution

There are a lot of Linux distributions that have the primary focus of becoming the next best desktop replacement for Windows or OS X. Of all the categories in this list, this is the most sought-after, and contentious, group of distros.
While it would be ideal to include many distributions on this list, the reality is that there really needs to be just one "best" Linux distribution. For early 2010, that distro has to be Canonical's Ubuntu.
Ubuntu edges out its closest contenders, Fedora and openSUSE, because its development team is constantly focused on the end-user experience. Canonical and the Ubuntu community have spent a lot of time and resources on bringing ease-of-use tools to this distribution, particularly in the area of installing Ubuntu and installing applications within Ubuntu.
In addition, Ubuntu's level of support for its desktop products is highly superior, which is important in this class of distributions since it is the most likely to contain users new to Linux. Both the official and unofficial Ubuntu documentation is robust and searchable, a big plus.

Best Linux Laptop Distribution

Laptop distributions almost fall into the same category as desktop users, but there are a number of key differences that make the criteria for evaluating a good laptop distribution important. Power management, docking tools, and wireless ease-of-use are critical to users on the go, as is having a distro that meets those needs.
Right now, the best laptop distribution is openSUSE, one of the lead contenders for the desktop honors. On the laptop, openSUSE shines with great connectivity tools, such as an easy-to-use networking toolset that not only handles WiFi connectivity, but also CDMA/cellular modem connections.
openSUSE also deals with docking stations for laptops very well, including dual-monitor management on the fly. Power management is very granular, which is great for detailing various power needs you might find yourself needing.

Best Linux Enterprise Desktop

This category is replete with great contenders as well, and it's difficult to highlight just one. At the end of the day, though, the nod must be given to SUSE Linux Enterprise Desktop (SLED).
The reason is simple: while SLED and its primary competitor Red Hat Enterprise Linux Desktop are nearly identical in features and support performance, SLED has the advantage of the openSUSE Build Service, a free and open service that lets applications be built and delivered to SUSE Linux and openSUSE products (as well as Red Hat and CentOS).
This is a very important differentiator in enterprise desktop development, as it means that SLED has the current advantage of application building and deployment in the enterprise arena.

Best Linux Enterprise Server

Again, in this category it really comes down to two main contenders: Red Hat Enterprise Linux (RHEL) andSUSE Linux Enterprise Server (SLES). Given the pick for the Enterprise Desktop category, you might expect SLES to get the "best of" label here.
But, when all factors for the enterprise server are weighed, RHEL is still the king of this particular hill.
Red Hat edges out Novell with its server product, because RHEL users get a deeply mature distribution, and Red Hat's support structure is second to none in the enterprise channels.

Best Linux LiveCD

As Linux technology improves, users can easily choose the LiveCD version of practically any of the Linux distros listed here to get the best LiveCD experience for their needs.
There is a specialized class of LiveCDs, however, that offers users utilities and tools for the specific purpose of repairing existing Linux and Windows installations. These distros are very useful to have regardless of what primary Linux distribution you like to use, because in a crisis they are invaluable to own.
In this class of distribution, KNOPPIX is hands-down the most complete and useful distro. Loaded on a CD or USB storage device, KNOPPIX will let you recover from nearly any rare Linux system crash as well as the much-less-rare Windows breakdowns.

Best Linux Security-Enhanced Distribution

Linux is inherently very secure compared to other operating systems, but there's always room for improvement.
One of the challenges for locking down Linux is if you are not careful, you can take away too much functionality. Another challenge is that the best security-oriented Linux distro, SELinux, is historically known to be difficult to configure correctly. Still, if security out of the box is your priority, this is the best place to begin.
Another approach is the white hat method: using security and forensic tools to examine your existing installation, determine the holes, then lock your system down based on what gaps you find. If you have the time and inclination, this is a great way to do it, because this will get any existing system more secure right away.
For the white hat approach, the best distribution is BackTrack Linux, a dedicated penetration testing distro that will enable you to safely try to crack any system you are caretaking. Its toolset and strong community give it the advantage in this category.

Best Linux Multimedia Distribution

General Linux distributions have come a long way in terms of multimedia performance. Rare is the audio or video file that can't be played on Linux. Music services such as Rhapsody and video sites like YouTube and Hulu are also standards-compliant and accessible to Linux users.
Still, for those users who are multimedia creators as well as consumers, there are Linux distributions that contain powerful tools for audio and video editing.
The best in this class is currently Ubuntu Studio. For audio, video, and graphic production, it contains a very complete set of tools, as well as format and codec support for a huge range of multimedia formats.
The applications contained in Ubuntu Studio are the same or similar to those used by major studios to create cutting edge work, so users are getting the best apps, coupled with the strong support ethos already found in the Ubuntu community.
In Linux there are as many opinions as there are lines of code. This represents one view of the best in Linux. What's yours?

Profile Linus Trovalds

Linus Benedict Torvalds (Swedish pronunciation: [ˈliːn.ɵs ˈtuːr.valds] ( listen); born December 28, 1969 in HelsinkiFinland) is a Finnish[2][5] software engineer and hacker, best known for having initiated the development of the open source Linux kernel. He later became the chief architect of the Linux kernel, and now acts as the project's coordinator. He also created the revision controlsystem Git.

Early years

Torvalds was born in Helsinki, Finland. He is the son of journalists Anna and Nils Torvalds,[6]and the grandson of poet Ole Torvalds. Both of his parents were campus radicals at theUniversity of Helsinki in the 1960s. His family belongs to the Swedish-speaking minority (5.5%) of Finland's population. Torvalds was named after Linus Pauling, the American Nobel Prize-winning chemist, although in the book Rebel Code: Linux and the Open Source Revolution, Torvalds is quoted as saying, "I think I was named equally for Linus the Peanuts cartoon character", noting that this makes him half "Nobel-prize-winning chemist" and half "blanket-carrying cartoon character".[7]
Torvalds attended the University of Helsinki between 1988 and 1996, graduating with a master's degree in computer science from NODES research group.[8] His academic career was interrupted after his first year of study when he joined the Finnish Army, selecting the 11-month officer training program to fulfill the mandatory military service of Finland. In the army he holds the rank of second lieutenant, with the role of a ballistic calculation officer.[9] In 1990, he resumed his university studies, and was exposed to UNIX for the first time, in the form of a DECMicroVAX running ULTRIX.[10] His M.Sc. thesis was titled Linux: A Portable Operating System.[11]
His interest in computers began with a Commodore VIC-20.[12] After the VIC-20 he purchased aSinclair QL, which he modified extensively, especially its operating system. He programmed anassembly language and a text editor for the QL, as well as a few games.[13] He is known to have written a Pac-Man clone named Cool Man. On January 5, 1991[14] he purchased an Intel 80386-based IBM PC[15] and spent a month playing the game Prince of Persia before receiving his MINIX copy, which in turn enabled him to begin work on Linux.[7][16]

Later years

After a visit to Transmeta in late 1996,[4] Torvalds accepted a position at the company in California, where he would work from February 1997 to June 2003. He then moved to the Open Source Development Labs, which has since merged with the Free Standards Group to become theLinux Foundation, under whose auspices he continues to work. In June 2004, Torvalds and his family moved to Portland, Oregon, to be closer to the OSDL's Beaverton, Oregon–based headquarters.
From 1997 to 1999, he was involved in 86open helping to choose the standard binary format for Linux and Unix. In 1999, he was named to the MIT Technology Review TR100 as one of the top 100 innovators in the world under the age of 35.[17]
Red Hat and VA Linux, both leading developers of Linux-based software, presented Torvalds with stock options in gratitude for his creation.[18] In 1999, both companies went public and Torvalds' share value temporarily shot up to roughly $20 million.[19][20]
His personal mascot is a penguin nicknamed Tux,[21] which has been widely adopted by the Linux community as the mascot of the Linux kernel.[22]
Although Torvalds believes "open source is the only right way to do software", he also has said that he uses the "best tool for the job", even if that includes proprietary software.[23] He was criticized for his use and alleged advocacy of the proprietary BitKeeper software for version control in the Linux kernel. However, Torvalds subsequently wrote a free-software replacement for BitKeeper called Git. Torvalds has commented on official GNOME developmental mailing lists that, in terms of desktop environments, he encourages users to switch toKDE.[24][25] However, Torvalds thought KDE 4.0 was a "disaster" because of its lack of maturity, so he switched to GNOME.[26] Dissatisfied with the loss of productivity, he switched to XFCE after the GNOME3 release, with another harsh post against GNOME.[27]

The Linus/Linux connection

Initially Torvalds wanted to call the kernel he developed Freax (a combination of "free", "freak", and the letter X to indicate that it is a Unix-like system), but his friend Ari Lemmke, who administered the FTP server where the kernel was first hosted for downloading, named Torvalds' directory linux.

Authority and trademark

As of 2006, approximately two percent of the Linux kernel was written by Torvalds himself.[20] As thousands have contributed code to the Linux kernel, such a percentage represents one of the largest personal contributions to the overall amount of code. Torvalds remains the ultimate authority on what new code is incorporated into the standard Linux kernel.[28]
Torvalds owns the "Linux" trademark, and monitors[29] use of it chiefly through the Linux Mark Institute.

Personal life

Linus Torvalds is married to Tove Torvalds (née Monni) — a six-time Finnish national karate champion — whom he first met in the autumn of 1993.[30] Torvalds was running introductory computer laboratory exercises for students and instructed the course attendants to send him ane-mail as a test, to which Tove responded with an e-mail asking for a date.[7] Tove and Linus were later married and have three daughters, Patricia Miranda (*5.12.1996), Daniela Yolanda (*16.4.1998), and Celeste Amanda (*20.11.2000),[31] two of whom were born in the United States.[5] Linux kernel's reboot system call accepts their dates of birth (written in hexadecimal) as magic values.[32]
Torvalds describes himself as "completely a-religious — atheist", adding that "I find that people seem to think religion brings morals and appreciation of nature. I actually think it detracts from both. It gives people the excuse to say, 'Oh, nature was just created,' and so the act of creation is seen to be something miraculous. I appreciate the fact that, 'Wow, it's incredible that something like this could have happened in the first place.'" He later added that while in Europe religion is mostly a personal issue, in America it has become very politicized.[33] When discussing the issue of church and state separation, Linus also said, "Yeah, it's kind of ironic that in many European countries, there is actually a kind of legal binding between the state and the state religion."[34]
In 2010, Torvalds became a United States citizen and registered to vote in the United States; he is unaffiliated with any U.S. political party, saying, "I have way too much personal pride to want to be associated with any of them, quite frankly."[5]

Recognition

Academics
In 1997, Torvalds received his Master degree (Laudatur Grade) from Department of Computer Science, University of Helsinki. Two years later he received honorary doctor status at Stockholm University, and in 2000 he received the same honor from his alma mater.[35]
In August 2005, Torvalds received the Vollum Award from Reed College.[36]
Industry
In 1998 Torvalds received an EFF Pioneer Award.[37] In 2000 he was awarded the Lovelace Medal from the British Computer Society.[38] In 2001, he shared the Takeda Award for Social/Economic Well-Being with Richard Stallman and Ken Sakamura. In 2008, he was inducted into the Hall of Fellows of the Computer History Museum in Mountain View, California.[39][40] He was awarded the C&C Prize by the NEC Corporation in 2010 for "contributions to the advancement of the information technology industry, education, research, and the improvement of our lives".[41]
Media
Time magazine has recognized Torvalds multiple times:
InfoWorld presented him with the 2000 Award for Industry Achievement.[45] In 2005 Torvalds appeared as one of "the best managers" in a survey by BusinessWeek.[46] In 2006, Business 2.0 magazine named him one of "10 people who don't matter" because the growth of Linux has shrunk Torvalds' individual impact.[47]
In summer 2004, viewers of YLE (the Finnish Broadcasting Company) placed Torvalds 16th in the network's 100 Greatest Finns. In 2010, as part of a series called The Britannica Guide to the World's Most Influential People, Torvalds was listed among The 100 Most Influential Inventors of All Time (ISBN 9781615300037).[48]
Space
In 1996, an asteroid (9793 Torvalds) was named after him.
Literature
The 1999 novel Cryptonomicon by Neal Stephenson features several characters who use "Finux", a Unix-like operating system developed in Finland.[49]
Patents
As of March 2011, Linus has been granted 35 patents worldwide (application and granted patents).[50]
