One of the great things about Linux (on the desktop) is the wide variety of options available. Linux, as many would say, “is all about choice”.
KDE or GNOME? RPM or Dpkg (Deb)? Red Hat or Debian? The various options available to Linux Desktop distros (distributions) are almost… limitless.
But which options, exactly, are people using? And how has that changed over the last several years? And what does that tell us about where Desktop Linux is going?
This is all incredibly difficult to answer due, in large part, to the difficulty of gathering reliable numbers on the usage of the various desktop Linux versions out there. And, even when good numbers are available for one Linux distribution, often those numbers are collected using a different method than another distribution.
The best source that I know of for “ranking” all of the various distros (based on how many hits each gets per day) is DistroWatch. This isn’t going to be 100% accurate, but it’ll give us a good indication on trending (and, from my experience, it seems to be fairly accurate).
So I took a look at the numbers DistroWatch provides for all of the “top distros” (this was me simply choosing the most popular distros over the course of several years) and put them in a chart covering 2003 to the present day.

Okay. That’s… interesting. And it gives us an intriguing peek at growth over the years. But these numbers are skewed by DistroWatch.com’s own growth as well as the general growth of Linux. What I really want is a percentage of the total Linux Desktop market-share…
So I took those numbers. Totalled them up. And created a chart of the percentage each Linux distro had, on average, during the course of each year. Obviously many great Linux distros are left out of this, and that has an impact on the numbers, but these represent the majority of the market-share at any point.

Now there we go! This paints a much more realistic picture of the market-share each Linux distro had during any given year (obviously still not 100% accurate… but about as close as we’re going to get).
Okay, a few things really jump out here.
2003/2004 was a very different time than what we have now:
- Mandriva (then called Mandrake) was king back in 2003, 2004!
- Fedora and KNOPPIX were in amazing shape with percentages in the teens.
- Debian, Gentoo and Suse are all doing quite well.
Then, in 2005, Ubuntu happened. Sure, it was released first in 2004… but in 2005, Ubuntu broke the 20% mark to become the “king of Linux distros”.
During that same year Red Hat and Mandriva took a hit that they never fully recovered from. Just look at that light blue line as it dips southward. Poor, poor Mandriva.
Flash forward to today… and things seem to have stabilized a bit. The only dramatic motion seems to be the decline of PCLinuxOS (from its perch as a “rival to Ubuntu” in 2007, down to the middle of the pack by the very next year) and, almost at the same time, the rise of Linux Mint, who came out of, seemingly, nowhere to challenge Fedora and openSuse for the number two spot.
But what does this mean? Does this give us any indication of where things are heading? To figure that out I decided to consolidate this chart to represent the “core” distros. Most distributions are built on top of other existing Linux distributions (Linux Mint, for example was based on Ubuntu). So I rolled all of these distros (where relevant) up into 4 “parent” distros.

In 2003 “Red Hat was Linux”. Or at least this is how many people thought. And, with a 40% market-share, of Red Hat and Red Hat-based Linux distros… that seems about right!
Then there’s that pesky 2005 again. Ubuntu-based distros (including Kubuntu, etc.) hit 25%. Catapulting Debian (which Ubuntu is, itself, based upon) up to over 45% and knocking Red Hat down to 30%. (With me so far?)
And Suse / openSuse… has stayed pretty much steady around 10% all these years (old reliable!).
Red Hat-based distros made a small come-back during 2008, but seem to be on the decline again.
Worth noting: Ubuntu-based is sitting at over 40%, with Debian-based sitting only a slight few percentage points higher (this is even with Debian proper taken into consideration).
What does this all mean?
- The vast majority of all Debian-based distributions of Linux (in terms of market-share)… are also Ubuntu-based.
- Fedora (and derived distros) are, by no means, out of the game. Owning over 25% of the market is a pretty big deal no matter how you look at it.
- But. Fedora is on a downward slide right now in usage it seems. While Ubuntu is on a slow up-tick (or staying roughly the same depending on how you look at it).
While I was at it, I wanted to also see which Desktop Environment each of these distros used. And how each stacked up over the years in terms of market-share.

Holy guacamole!
I knew KDE was a bit down (in usage) from its heyday. But that’s a pretty extreme drop!
KDE and Gnome seem to have, over the course of about 3 years, switched spots. With most of the movement in… you guessed it… 2005. It’s that silly little Ubuntu again. When Ubuntu hit, and went big, it pulled Gnome up with it.
And KDE still seems to be on a slight downward slope (despite or, perhaps because of, the release of KDE 4).
So where does that leave us? Where is desktop Linux heading?
There are still some unknowns. But a few things are becoming clear:
The “Linux World” (and, by that, I mean people who actually use Linux as a desktop system) is gravitating towards Ubuntu and GNOME. In large numbers.
Does that mean KDE, Fedora, Suse, etc. are dead? No sir! All of the distros listed above still command a very healthy market-share and dedicated user base.
But these other distros are quickly becoming “Ubuntu Alternatives“.
That’s a pretty major change from where things stood in 2003.
And I think it is awesome.
Why? I’ll give you two big reasons:
- It allows a clear, consistent image of “Linux” to be portrayed to the general public.
- It allows developers (of both open source and closed source commercial software) to focus on one single environment first. This can save a great deal of time and money, and allow for higher quality software.
Some people may not like this (okay… I know many people who don’t like this), but it simply looks to be the way things are going. I’d be willing to bet that, in a few years, people will equate “Ubuntu” with “Linux”.
But really, it’s not like the other choices have gone away. And it’s not like the Linux Action Show is going to suddenly become the “Ubuntu Action Show” or something nutty like that. But the numbers don’t lie.
