Extending Ubuntu's Battery Life

Last week when traveling to Europe for FOSDEM and other business meetings, I had picked up a new 9-cell battery for a Lenovo ThinkPad T60. While an additional three battery cells will noticeably extend your battery life, you can also extend your battery life by taking a few simple steps to optimize your Linux desktop that will also reduce your power consumption and heat output. In this article are a few simple steps to take in order to extend your notebook's battery life on Ubuntu.

Kubuntu 8.04 KDE 4 Alpha

Canonical will not be officially supporting KDE 4 until Kubuntu 8.10 "Intrepid Ibex" but for Kubuntu 8.04 "Hardy Heron" will be a KDE 3.5 spin and then a community-supported Kubuntu 8.04 version based upon KDE 4.0 (though a few KDE 3 applications are still bundled). Arriving today, albeit a week after the Ubuntu 8.04 Alpha 5 release, is the first KDE 4.0.1 Hardy Heron build.

Measuring Ubuntu's Boot Performance

Last year leading up to the release of Ubuntu 7.04 "Feisty Fawn" and Ubuntu 7.10 "Gutsy Gibbon" we had published several articles looking at various aspects of this desktop Linux distribution. These articles had varied from looking at Ubuntu's power consumption for the past six major releases to presenting the visual history of Ubuntu and how its graphics have evolved since Ubuntu 4.10. With Ubuntu 8.04 "Hardy Heron" shipping in just two months, we are once again looking at Ubuntu from several points of view. In this article, we are looking at Ubuntu's boot performance for the past five releases through the use of Bootchart for measuring its boot time, disk throughput, and the running processes.

OpenSuSE 11.0 Alpha 2

With the alpha one release of OpenSuSE 11.0 we had talked about its brand new installer that was powered by Trolltech's Qt4, and now with Alpha 2 becoming available there are more notable improvements. OpenSuSE 11.0 will ship with GNOME 2.22, but until that is available there is GNOME 2.21.90, which is the latest development build. For KDE users, Alpha 2 has integrated KDE 4.0.1 which replaces the KDE 3.5 branch for this desktop Linux distribution. OpenSuSE 11.0 Alpha 2 contains the Linux 2.6.24 kernel, D-Bus 1.2-rc2, ALSA 1.0.16-rc2, and other new open-source packages. Alpha 2 is available via GNOME and KDE LiveCDs and an installation DVD that contains only open-source software.

Myah OS 3.0 Beta 1

Hitting the web this past week in addition to Fedora 9 Alpha, OpenSuSE 11.0 Alpha 2, and Yellow Dog Linux 6.0 was the first beta release for Myah OS. This is a desktop Linux distribution that is assembled via custom build scripts and its own package management solution. This beta release brings forth a GUI front-end for the Myah Package Manager, Myah update icon applet, live installer support for EXT3/XFS/ReiserFS, and live installer support for installing to a USB flash drive. Myah OS 3.0 Beta 1 ships with the Linux 2.6.23.14 kernel, GCC 4.2.2, Xfce 4.4.2, and X.Org 7.3. While Myah OS is a one man operation and its developer, Jeremiah Cheatham, goes to the extent of creating a truly custom distribution, it's unfortunate that the theme and even the cursor are abominable from our perspective. Aside from that, it's an interesting distribution.

Solaris Express Developer Edition 1/08

In addition to Project Indiana Developer Preview 2, Solaris users can now rejoice over the next release in the Solaris Express Developer Edition family. SXDE 1/08 is the quarterly update to Sun's next-generation Solaris Operating System that is built from the latest OpenSolaris Nevada technologies. This first SXDE release of 2008 brings a host of new features for the developer such as NetBeans 6.0 and the GlassFish v2 application server. Even for those that aren't developers, SXDE 1/08 brings new features further down on the Solaris stack such as the Sun xVM virtualization server with support for libvirt, support for the Intel 4965 wireless chipset with 802.11n capabilities, and a variety of new services.

Fedora 9 KDE Live Alpha

With Fedora living on the front-line of Linux technologies, Fedora 9 Sulphur will be shipping with KDE 4.0 as opposed to holding off until KDE 4.1 with Fedora 10. With the release of Fedora 9 Alpha this morning, we've taken both the GNOME and KDE versions for a test spin. While this alpha release is shipping with KDE 4.0.0, and Fedora 9 final release will likely ship with KDE 4.0.3, this desktop LiveCD had worked out fairly well in our initial usage tests. For your viewing pleasure we've included some screenshots of Fedora 9 KDE Live Alpha.

Fedora 9 Alpha Preview

On this Super Tuesday here in the United States, Red Hat has this morning released the first and only alpha release for Fedora 9. This ninth Fedora release, which has been codenamed Sulphur, will ship in April and go head-to-head against Ubuntu 8.04 LTS "Hardy Heron", but what features can one expect in this forthcoming release? Among the features being worked on are encrypted file-system support, updating the KDE spin to KDE 4.0, PackageKit integration, and switching to upstart initialization. In this article, we are taking a brief look at Fedora 9 Alpha and the features planned for Fedora 9.

Ubuntu 8.04 Hardy Heron Alpha 4

Ubuntu 8.04 Alpha 4 was released yesterday afternoon and today we have screenshots of this latest Hardy Heron development release. Alpha 4 integrates the latest GNOME 2.22 packages such as Vinagre and Brasero, introduces a world clock applet, and virtualization improvements that we already talked about earlier in the week. Ubuntu 8.04 Alpha 5 will ship in late February and the final release will come this April.

Virtualization Made Easy In Ubuntu 8.04

One of the features that was introduced a year ago into Ubuntu 7.04 "Feisty Fawn" was support for KVM, which is the Kernel-based Virtual Machine. The Kernel-based Virtual Machine provides full virtualization support for Linux when running on x86 hardware with either Intel's VT or AMD-V technology, which means you can run unmodified guest operating systems such as Linux or Microsoft Windows within your Linux host operating system. As we had shared in benchmarks, KVM -- even back to its infancy -- has been quite fast at virtualization when compared to Xen or kqemu. However, the KVM virtualization support found in Ubuntu hasn't been the most user-friendly. Installing and then managing these guest operating systems in Ubuntu 7.04 and Ubuntu 7.10 has required using the command-line interface and thus requiring the user to be familiar with the various QEMU options. However, in Ubuntu 8.04 this has all changed for the better now that virt-manager and libvirt are available from the main Ubuntu repository.
