Today is Ubuntu 9.10 Karmic Koala artwork deadline which means all the artwork will remain unchanged from now on, until Karmic is released. There have been a lot of updates today, so let's take a look at how Ubuntu Kamic Koala will look like.

I'll begin with the end :) meaning the log-out screen which I saw as soon as I updated and wanted to restart Karmic Alpha 6:

By default Ctrl + Alt + BackSpace key combination in Ubuntu Jaunty was disabled.This shortcut key is used  to restart X.This tutorial will explain how to enable this key combunation.

I decided yesterday to upgrade from Ubuntu Intrepid to Jaunty (Release Candidate). Alt + F2 and typed: update-manager -d

and after the restart I only had a few minor issues:

My Amarok was upgraded from 1.4 to 2.0.2 and I had to rescan the music collection and also my custom playlists were gone. I had to drag each playlist into Amarok and then save it again. That fixed one issue. [...]

Latest release of Ubuntu 9.04 codenamed Jaunty Jackalope has few annoyances for experienced users such as Indicator applet, No default Compiz/desktop effects for some Intel based motherboards, Update manager nagging continuously for updates, cant restart X server by Ctrl+Alt+Backspace key combination etc. This article will enlist the fixes or workarounds for these annoyances.

Ubuntu 9.10 Karmic Koala simply have do an apt-get upgrade to update to the latest KDE 4.3 (which was released yesterday) but (K)Ubuntu 9.04 Jaunty Jackalope users have to add the Kubuntu PPA backports so they can install the latest KDE 4.3.

New in Ubuntu Jaunty Jackalope (9.04) Alpha 6: the installer's revamped timezone map (see the fourth screenshot on the third row). The notification system was improved. Also, The GIMP has only one entry in the panel and not three, or two if you leave only the Toolbox opened (see the fourth screenshot on the first row).

There have been proposed quite a few themes for Ubuntu Karmic Koala 9.10 and if you want to install them all in Ubuntu Jaunty for instance, you can just do:

sudo apt-get install community-themes

In this context, a one-liner is a set of commands normally joined through a pipe (|). When joined by a pipe, the command on the left passes its output to the command on the right. Simple or complex, you can get useful results from a single line at the bash command prompt.

Ctrl+Alt+Backspace (i.e. the shortcut which was used to restart the X server) has to be enabled in a different way with respect to previous releases of Ubuntu.
This is due to the fact that “DontZap” is no longer an option in the X server and has become an option in XKB instead.
