When you think of Ubuntu Linux, what do you think of? I would guess you think about the Linux desktop. While Ubuntu is certainly a big player—maybe the biggest—when it comes to the Linux desktop, Mark Shuttleworth, founder of Canonical, the company behind Ubuntu wants you to know that “A remarkable thing happened this year: companies started adopting Ubuntu over RHEL for large-scale enterprise workloads, in droves.”
Since last summer, Ubuntu has been more popular than Red Hat as a Web server.
Shuttleworth makes this claim because, according to W3Tech, which surveys technologies used on the Web, shows that since July 2011 Ubuntu has overtaken Red Hat Enterprise Linux (RHEL) for Web servers. According to W3Techs, as of February, “Ubuntu s now used on 6% of all Web servers, up from 4% one year ago.”
Now Cloud Market is measuring Amazon Machine Image (AMI), a pre-configured operating system and virtual application software which is used to create a virtual machine, not the number of running systems. As Shuttleworth told me during our e-mail discussion of Cloud Market’s data “I would characterize it as an easily gamed measure of innovation (i.e. a measure that will become less useful if lots of people start talking about it :-) rather than a measure of adoption. It’s a measure of how many people have taken the OS and done their own snapshot with their own customizations, not a measure of how many of each of those images is running.” Since, however, no one to my knowledge has been looking at Cloud Market’s data in this way it strikes me as still showing serious business server interest in Ubuntu.
Ubuntu images are by far the most popular operating system images on the Amazon cloud.

This guide is simple to follow, with step-by-step instructions and plenty of screen shots, allowing you to discover the potential of your new Ubuntu system even if you are a novice computer user or are migrating from another operating system for the first time. Getting Started with Ubuntu is not intended to be a comprehensive Ubuntu instruction manual. It is more like a quick-start guide that will get you doing the things you need to do with your computer quickly and easily, without getting bogged down with technical details.
Here’s a quick rundown of some of the release’s key highlights.
1. A taste of HUD
As hinted by Canonical founder Mark Shuttleworth in late January, Ubuntu’s new Head-Up Display, or HUD, interface makes its debut in this beta version. Dubbed by Canonical as “a new way to quickly search and access any desktop application’s and indicator’s menu,” HUD can be accessed by pressing the Alt key and typing in a description of what you want to do. The OS then returns a set of corresponding entries, including some fuzzy matching, the project team says. Over time, it also learns from your previous choices to make the search more and more accurate, they say.
2. Unity tweaks
Ubuntu’s Unity interface has been nothing if not controversial, but in this new release, the Appearance panel in the OS’s system settings lets you more easily configure some properties of Unity. For bookmark users, the Unity launcher now also includes Nautilus quicklist support.
3. Clickpad support
Ubuntu 12.04 includes support for clickpads, which are trackpads on which the physical button is integrated into the trackpad surface. Most Synaptics clickpads are recognized out of the box in this new release, as are Apple MacBook trackpads. Coming in Ubuntu’s next release will be support for Apple’s Magic Trackpads and more Synaptics-branded devices, the Ubuntu team says.
4. Power savings
For the aforementioned power savings, RC6 — the technology that allows GPUs to go into a very-low-power consumption state when the GPU is idle — is now enabled by default for Intel Sandy Bridge-chip-based systems. The result can be improvements of between 40 and 60 percent in power usage under idle loads, the developers say.
5. LibreOffice 3.5 and Rhythmbox
Among the default applications in Ubuntu 12.04 are the newly updated LibreOffice 3.5, as well as Rhythmbox as the default music player.
6. Better language support
When users install new software through the Ubuntu Software Center, the corresponding language support packages — including translations and spell check modules — are now installed automatically as well, thus eliminating the need to open Language Support after installing new software.
7. A fresh kernel
Finally, upgrading from the second alpha release of “Precise Pangolin,” this new beta version includes the 3.2.0-17.27 Ubuntu kernel, which is based on version 3.2.6 of the upstream stable Linux kernel.
