With Unity getting most of the attention lately in Ubuntu and the feature-freeze coming in tomorrow, I decided to take the latest Kubuntu alpha for a spin and see how KDE 4.8 for netbooks looks and behaves. But first, a little about 12.04 as a whole.

Ubuntu 12.04 Precise Pangolin will be the next long-term supported release and as most of you already know, it is scheduled to arrive at the end of April 2012. Here is the release schedule of Ubuntu 12.04: <!--more-->

    <li>Alpha 1 - December 1, 2011 <li>Alpha 2 - February 2, 2012 <li>Feature freeze - February 17, 2012 <li>Beta 1 - March 1, 2012 <li>Beta 2 - March 29, 2012 <li>Release candidate - April 19, 2012 <li>Final release - April 26, 2012


The 12.04.1 point release is scheduled for July.

This review is based on the latest Kubuntu alpha, after a clean install and performing a full upgrade using sudo apt-get update && sudo apt-get dist-upgrade.

I had a look at Plasma Netbook, by running the live ISO image on an Acer Aspire One D255E netbook from a USB flash drive. The netbook is equipped with an Intel N570 1.66 dual core CPU, 2GB RAM and Intel HD 3000 integrated graphics card.

Here are the main features available in Kubuntu 12.04:

    <li>Kernel: Linux kernel 3.2.0 <li>Desktop environment:KDE Software Compilation 4.8.0 <li>File manager:Dolphin 2.0 <li>Web browser:Rekonq 0.8.71 <li>Music player:Amarok 2.5.0 <li>Terminal: Konsole 2.8


Kubuntu correctly detected the netbook and started off the USB drive directly in Plasma Netbook, it detected the graphics card and enabled desktop effects by default, also the Ethernet card, wireless and webcam worked out of the box.

The KDE interface for small screens is really nice in my opinion, and pretty much a lot more functional than Unity if you ask me.

By default, the desktop looks like this:



There is a strange artifact consisting of some blue vertical stripes in the search box, but other than that, the "Search and launch" page really looks pretty neat.

From left to right, the upper panel bar includes the menu of the currently selected application, the Search and launch page, another page titled "Page one" to which various Plasma widgets can be added (like a weather widget, or a web browser). In addition to these, we have the system tray with Klipper, volume icon (KMix), laptop battery icon, network icon, date and time. Options to lock screen and shutdown are also available.

On the top-right side there is an application selector, which, when clicked, shows a list of all the running applications.

To be honest, I could never familiarize with these interfaces designed for small screens, and Unity in Ubuntu seems to me strange and unusable even now. The idea of having to do additional clicks in order to select an application, or switch your hand from mouse to keyboard and viceversa doesn't look fast, but I guess that's just me. However, KDE really does a good job implementing the netbook interface. One of the thing I still miss is the Alt+F2 run box which doesn't seem to work in Plasma Netbook.

Here's the Search and launch page with changed wallpaper and shortcuts to some applications:



Configuring search and launch:



And the widgets page:



Moving forward, here is the default music player which ships with Kubuntu, Amarok 2.5.0:



Amarok has reached a level of completeness, one of the only drawbacks being the fact that it's pretty slow, and I'm talking about scrolling in a large default playlist (with album thumbnails enabled) and resizing its three main widgets (services, context and playlist). I guess this has to do something with Qt.

Dolphin, the file manager:



Rekonq the default WebKit-based web browser comes with support for HTML5:



To conclude, Kubuntu Plasma Netbook is pretty cool and intuitive, offering fast access to common applications, a pretty solid interface, and the best of them all, it is, as KDE always was, highly configurable. Hopefully the 12.04 release will be a good improvement over the last Kubuntu versions.

Very nice summary and I have couple comments.

  • 1. It would be helpful to mention that the Plasma Netbook interface comes already installed and is available as an option even in the desktop interface. One can switch between Plasma Desktop & Netbook interface by going to "Settings" => "System Settings" => then under "Workspace Appearance & Behavior" select "Workspace Behavior" => Workspace => then select "Netbook" from dropdown "Workspace Type"
  • 2. One cosmetic issue is the closing tags of the lists are missing

Whew! I thought E17 used too many nested settings xD.

This isn't something users do that often and It could be made as one click using a short cut or script, but for better organization of the unprecedented level of KDE configuration, it is included in the group it belongs to.

Besides, switching interface on the fly without reboot or re-login, E17 or any other desktop for that matter, have no such capability. Not even in their dreams.

I beg to differ. Metacity and several other window managers have the "--replace" option, which allows the user to terminate the current WM and replace it with a new one.

And yes, I know I'm not talking about a full Desktop Environment. But some of us prefer a highly-customizable WM that obviates the need for all that extra desktop flotsam and jetsam. (Yay Sawfish! Yay Lisp!)

You are right, and below is a snippet of what its developer said about it. But my point was about how features rich, extensible, yet organized KDE has become. Many users consider such wealth a big advantage over simplicity and lack of functionality. Besides, many of the features and capabilities don't stand in the way, and if they are not needed or used, users won't even notice them.

Quoting: Edited: From wikipedia

Metacity's focus is on simplicity and usability rather than novelties. Its author has characterized it as a "Boring window manager for the adult in you. Many window managers are like Marshmallow Froot Loops; Metacity is like Cheerios."[4] People in favour of Metacity say that it is aimed at new computer users who do not need the abundant options and functionality of Sawfish or Enlightenment.[5] Havoc Pennington wrote an essay explaining why he wrote Metacity and simplified the GNOME desktop.[6] Devil's Pie and Brightside are among the packages that enable increased control over windows, however these applications cannot override Metacity's key bindings.

Exactly: how often are you going to switch between desktop mode and netbook mode anyway? It's probably a one-time change for the people who actually use it, and then they leave in that mode forever.
