Kubunti Karmic Koala 9.10 on a Netbook

The Kubunti Karmic Koala 9.10 version was released in October 2009.[1] There are major improvements in the KDE desktop and the installation process and options with this release. My overall impressions are that Karmic Koala 9.10 is polished, easy to use, stable and quite slick. For those thinking of moving from Windows XP or Vista, this is a compelling option.

You can test Kubunti Karmic Koala from a live CD to determine how well it runs on your hardware.

If you have a netbook without a CD drive, you can test it by creating a bootable USB drive. Once installed on the USB drive, you can save settings, install software updates and new applications and give it a thorough road test.

I was able to get the Bluetooth mouse and Wifi connection working without any problems.

You can then use the same bootable USB drive to install Kubunti Karmic Koala onto your netbook. No CD drive or Internet connection is required to do this.

The first applications I installed were Firefox (3.5.6), Picasa and the Google Chromium browser.

Creating a live CD

  1. Download the live CD image (.iso file) from here: http://www.kubuntu.org/getkubuntu
  2. Burn the image file to a CD with a CD burner
  3. Put the CD into your CD or DVD drive, enable "boot for CD" in your bios settings, reboot your machine and Kubuntu will load

Creating a bootable USB drive

This article contains information on how to create a bootable live USB drive with Kubuntu 9.10. Follow the instructions and select the Kubuntu image instead of the Ubuntu one.


You can then boot from the USB drive to confirm that Kubuntu is for you, and runs on your hardware.

Backup your existing operating system and data

Before you install a new operating system it is wise to backup all your existing content (documents, images etc) and your operating system partition.

Another bootable USB drive with the appropriate applications can be used for this. Two options for this are:

Installing Kubuntu from USB drive

When you are ready to take the plunge, you can install Kubuntu from the same USB drive - it is an option on the boot menu. Note that this option will install a "vanilla" version of Kubuntu; any changes or configuration you made to your bootable USB version will not be replicated.

The installation process is simple and easy. The process includes automatic creation of two Linux partitions - you just select how much disk space you wish to allocated. I chose 30MB - half of the available DATA partition I had.

I left my Windows XP partition intact so I can boot it if I need to.

The GRUB boot loader is part of the install, which allows you to select Kubuntu or Windows when your machine boots from its hard disk.

You can access Windows NTFS drives from Kubuntu - they appear in the Dolphin file manager. However, you cannot access the Linux drives from Windows XP.

Installing applications on Kubuntu

Kubuntu comes with a good range of applications installed, including the OpenOffice suite and a good text editor (Kate). Many more applications are available that are easy to install.

Setting up repositories

Kubuntu is initially configured to only use repositories that conform with open source licences. You can easily add additional repositories so that software from other sources that may not be fully open source - such as some media codecs and some Google applications for example.

To install Google applications that are not in the standard Ubuntu/Kubuntu repositories:

  • go to KPackageKit settings
  • click Edit software sources
  • enter your admin password
  • click Other software tab
  • enter the software sources illustrated below by clicking on the Add button
deb http://dl.google.com/linux/deb/ stable non-free
deb http://dl.google.com/linux/deb/ testing non-free
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main (Source Code)
deb http://packages.medibuntu karmic free non-free

Using KPackageKit

Start the KPackageKit package manager, then search for the application name (e.g. Picasa), select it and click Apply to install it

I added the following applications using KPackageKit:

  • Picasa, image handling and viewing, from Google
  • Chromium browswer from Google - I like the speed and the bookmark sync
  • Google Desktop - for searching content on PC
  • GIMP - graphic editing. Install via KPackageKit add/remove applications.
  • Firefox 3.5.6 browser. Installation program included with Kubuntu.
  • Grsync - for syncing folders. Install via KPackageKit add/remove applications.
  • Kdenlive - video editor. Install via KPackageKit add/remove applications.
  • Audacity - sound recorder. Install via KPackageKit add/remove applications.
  • VLC - media player. Install via KPackageKit add/remove applications.
  • Google Gadgets GTK - eye candy, not using this

Installing applications manually

Applications I installed manually include:

  • Skype - Download skype-ubuntu-intrepid_2.1.0.47-1_i386.deb then click on the file to install it. NOTE: Version uses the PulseAudio sound system - I have not been able to get the microphone working. I installed the previous version to get the mic working, but the volume is very low so it is not really usable.
  • Krusader file manager. Install from a teminal (Console) command line using this command: sudo apt-get install krusader.

Installing Windows applications

It is best to find native Linux applications for the tasks you want to complete. If you cannot find a suitable native Linux app, there are two main options for running legacy Windows applications under Kubuntu Linux:

1. Install a virtualisation environment such as Virtualbox then install your copy on native Windows under it.

  • Requires physical allocation of memory to the virtual machine

2. Install WINE packages that implement the Windows API in Linux and allow you to run Windows applications directly under Linux

  • Uses less system resources
  • Not all applications run well under WINE - check the WINE application database to determine this.

Features of the KDE desktop

Kubuntu's KDE Kwin window handler can provide some interesting and useful special effects. Here are a few to try:

  • Ctrl+F12 hides windows and puts widgets in front.
  • Alt-F2 displays KRunner application in which you can type a command or word and it will locate a matching program to run
  • Ctrl-F8 displays all desktops as tiles

If you have the Desktop Effects enabled, CTRL+F8 shows a full-screen overview of your workspaces.

KWin lets you easily move windows by pressing the ALT button. You can then just click on a window's content. While you hold the left mouse button pressed, windows will move. Hold ALT pressed and click on the right mouse button to easily resize a window. No need to aim precisely, just keep ALT pressed and manipulate your windows easily!

Present Windows gives you an overview of your open windows. Push the mouse cursor to the top-left corner of the screen and press to arrange your windows side-by-side. You can click on a window to get it focused in front of you. Start typing a word from the label on a window and matching applicatons will be filtered. Hit Enter to switch to the chosen application. You can activate the Present Windows effect also with the keyboard through Ctrl+F9 or Ctrl+F10 to show windows from all virtual desktops.

See KDE 4.0 Visual Guide: Desktop for more information.

Installing Gnome on Kubuntu

Kubuntu share the same Debian Linux core with Ubuntu, but Ubuntu uses the Gnome desktop instead of KDE. You can install and use the Gnome desktop in Kubuntu then choose which desktop you want to use when you login. This allows you to try out Ubuntu without doing a full separate installation. Some other Linux distros such as Fedora, provide both KDE and Gnome desktops as part of their standard packages. That is one of the great advantages of Linux - choice. On the flipside, choice can introduce complexity or unwanted options too.

Note: Installing the Gnome desktop can clutter application menus with both Gnome and KDE applications, which may be a little confusing to some.
