I started on my laptop with Ubuntu Gutsy 7.10 and then reinstalled everything to get Hardy Heron 8.04. To get KDE 4.0 I first installed the Kubuntu Desktop using this command in terminal:

sudo apt-get install kubuntu-desktop

then, after booting into Kubuntu and trying it for a few weeks, I installed KDE 4.0 (or Kubuntu's version of that) by using the Adept Manager (Kubuntu's version of Gnome's (ubuntu's) Synaptic Package Manager) and doing a search for kde4.

First, though, you have to add this line to your sources list:

deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main

(don't forget to reload your sources afterwards!)

I actually installed several packages which came up, but all you need is one, which you can install through the terminal with this command:

sudo apt-get install kde4-core

I had tried to get on PUU a month ago or so but was not accepted because I had sent a picture of the back of my head instead of a proper hackergotchi.  I was to lazy busy to create one, so yesterday I finally decided to do it and try again.  I am glad that I did. There are lots of how-to's on the 'net you can follow that can help you if you don't know what to do, I used Nicu's How-to as a guide.  I was going to write a how-to on using gimp but there are so many of them already I decided against it.

While I was looking for a picture of myself to change into a hackergotchi, I decided to change two of my computers desktop backgrounds.  The first one is "kramer", my laptop.

The second one is "babu", my eeePC.

I'll leave you with that.  The next post should have more substance.

I decided to keep openSUSE 11 KDE 4 on one box, Ubuntu on the laptop, Ubuntu on the eeePC and on the last box I'll be getting rid of Kubuntu 3.5.9 and going with something else.  I am debating between GoblinX and Elive.  Both of them have new releases this week and I have been waiting for both of them to try them out.  One of them will be left on a computer for longer than a few days, I don't know which one yet but I will find out pretty soon.

I really like Ubuntu they have a fine product but I cannot use Kubuntu anymore or until Canonical decides to put more resources towards it.

In my Kubuntu installs I am using Konqueror. I had said that Konqueror is slow. Not anymore, Konqueror is faster than anything I have tried. I don't know what the did but it worked. I do have issues with the KDE 4 version on Konqueror, such as not being able to play streaming audio. I have no such problems with Konqueror in KDE 3.5.9. At work I have installed Safari from Apple to give it a go, but I haven't done any thing with it yet.

I haven't been using Opera since updating my computers, but as soon as I finish this post I'll be installing it on the KDE 4 computer and hopefully It'll have streaming audio working. I'll let you know.

One of the installs was for another co-worker and I am glad that I did not have to install Windows again. GNU/Linux is a pleasure to install whilst Windows is hard work to install.  By the end of the weekend I have two more installs to do and then I rest for a while.

If you haven't tried Ubuntu/Kubuntu/Xubuntu/Mythbuntu/...buntu now is the time.  It is a great distribution.

Perhaps so, but KDE 4 development seems to be following this paradigm to the fullest -- enough to make Stephen King proud!

KDE 4 has a laudable goal of revitalizing the internals, making the underlying framework robust and extensible. This is a reworking of function, perfectly acceptably and a valid developmental goal. KDE 4 also went the bling-bling way of oooh-- shiny new interface at the same time.

The result?

It's a dog's lunch at the moment, stretching developer resources and skewing schedules. Notwithstanding a grand launch of KDE 4.0 which is ready yet not ready for general consumption (go figure!). After all, we're real software developers and not language lawyers!

This is not a commentary on the state of KDE 4, but rather on the simultaneous reworking of form and function which resulted in neither being complete for a general use... yet.

Of course, the oft-repeated refrain is... KDE 4 will rock with release 4.1!

Yeah. Right!

Replace KDE 4 in the above commentary with Mac OS X, Microsoft Windows or any but-it's-going-to-change-computing-forever software system... the end-result is the same!

After the seeing how smoothly Ubuntu was updated on my laptop, I decided to update my Kubuntu 7.10 to 8.04 beta.  I already am using the KDE 4.0.3 version of Kubuntu 8.04 so the next step was the KDE 3.5.9 version of Hardy Heron.  This time the update was very painful.  I had to install it from scratch after the update because I could not do anything with it.  Thank God for live cd's because there were some data that I had not backed up before attempting this update.  From what I have been experiencing Kubuntu is buggier than Ubuntu.  The KDE 4 version of Kubuntu has less bugs from my experience.  Everything will be fixed by April 24th and both Kubuntu distros will be great.

I installed Foresight 2.0 for another few hours.  I like the new features in Gnome 2.22, but since I am already using Gnome in Ubuntu I decided to remove Foresight and wait for Ubuntu 8.04 Hardy Heron to try out Gnome 2.22, only a bit more than a month to wait.

I settled with the installation of Kubuntu 7.10. So I now have KDE 4.0.2 with Kubuntu 8.04 Alpha, I am going to use both new releases of Kubuntu when they come out until I can truly say that KDE 4 meets all my requirement.  Well that is it for this installment.

Today I updated my OpenGEU computer and this broke two packages. This is the second time that I have broken packages with this Operating System once when it was call GEUbuntu and today. I restarted the computed and now I can't log on! I don't have the time to fool around with this so I try to install GoblinX on this computer, the gtkHDIstall is broken so it does not install unless we edit it there is a typo in the code. I fix this and I am installing as I am writing this.

If you have read my last post you will know that I was very pissed off that some schmuck copied my blog without giving me credit for writing it. Now I don't mind that it was copied and I will allow anybody to copy this blog just as long as I am credited in writing the blog and you must have a link to this blog.

GoblinX is done installing I am booting up, it works! I'll explore it and tell you about it in a future post because I have a ton of things to do.

GoblinX is done downloading. I decide to search for a solution to my problem and decide that if I can't fix it I would try GoblinX. I find a solution. Apparently using Kubuntu is not recommended for English Canadians. The en-ca language pack is what was screwing up my Kubuntu logging. To fix this I had to remove the English Canadian language pack from my computer and everything now works fine.

Now my adventure with my OpenGEU computer. Last week I had lost sound on this box and after 30 minutes of searching I find out that I had to reinstall emodule-mixer and alsa, remove the mixer from the shelf it was one, restart the computer and when the computer was back on put the mixer back on the shelf. The sound was back. After an update on Wednesday I had no sound again. I repeat what I did last week and I have sound again. I hope I don't have to do this after every updates. I decided that if I have to do this I'll install GoblinX on this computer.

GoblinX will be installed on a virtual machine this weekend because I am intrigued with it. I'll let you know about it in a future posting.

Jetzt, wo ich KDE 4.0 auf meiner Spielwiese Gentoo installiert habe, will ich auch noch mal meinen Senf zu dem Thema abgeben.

Wie ich einigen Posts im o.g. Forum entnehme, hat der Großteil derjenigen, die KDE 4.0 nutzen, den Sinn und Zweck dieses Releases falsch verstanden - genau wie ich. Allerding bin ich auf meinen Recherchen auf einige interessante Links gestoßen.

Die Quintessenz ist hier auf der OpenSuSE-Seite zu KDE 4 zu finden. Bevor wieder weiter über das KDE4 gemecktert :D wird, sollte man sich diesen Artikel zu Gemüte führen. Mir hat er jedenfalls das eine oder andere Auge geöffnet.

Zusammenfassend sollte man wissen, dass die veröffentlichte Version KDE 4.0 weder KDE 3.5x ablösen, noch als dessen Nachfolger verstanden werden soll.
Diese Version dient eher dazu, schon mal das Gerüst für die Folgeversion für 4.1, die man dann wohl als "Nachfolger" betrachten kann. 4.0 stellt lediglich den Rahmen dar, der es den KDE-Entwicklern ermöglichen soll, ihre Programme auf dessen neue Architektur zu portieren. Er wurde also mehr für die Entwickler veröffentlich, als dass er zum ausschließlichen Einsatz gedacht ist.

Hier ist noch mal eine kleine englischsprachige Zusammenfassung: KDE 4.0 is not KDE4.

Die Version 4.1 ist für das 3. Quartal geplant - was natürlich erahnen lässt, dass auch Kubuntu Hardy Heron bis zu diesem Zeitpunkt mehr schlecht als recht mit dem neuen KDE arbeiten wird.

Zu meiner Erfahrung:

Die Testversion unter Kubuntu lief erwartungsgemäß schlecht. In der Gentoo-Version (nach dem Release installiert) läuft er recht stabil. Bekannte Probleme bestehen aber auch hier noch. Alles zusammen find ich ihn recht gelungen, schneller als KDE 3.5.8 und auch einige neue Konzepte super gut.

Zum Schluss nochmal ein zusammenfassendes Zitat von der o.g. OpenSuSE-Seite: "Wenn es ihre Bedürfnisse bereits erfüllt, freuen Sie sich; falls es das nicht tut, dann ist es das, was Sie von 4.0 erwarten sollten."

I did reformat the computer that I had elive installed on. Now it has OpenGEU, which for those of you that don't know is the re-vamped version of Geubuntu. This computer I have been using on a daily base. It is a fine environment for a computer with limited resources. Everything else is the same.

Lo primero que tenemos que hacer es abrir el archivo source.list para añadir un nuevo repositorio a la lista de los ya existentes:

gksu gedit /etc/apt/sources.list

Copiamos el siguiente texto y pegamos al final del documento:

## KDE 4
deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu gutsy main

Actualizamos los repositorios:

sudo aptitude update

Instalamos KDE 4.0:

sudo aptitude install kde4-core

Una vez hecho esto reiniciamos el PC y en la pantalla de login, en sesiones, seleccionamos KDE 4.0.

Let's say we select Logout. This generates the following dialog:

It's always good to have a choice, a second chance to change one's mind. But it does seem slightly overkill asking confirmation for the options selected from the kickoff menu earlier.

While there are definitely valid use-cases for the End Session dialog (such as electing to terminate a KDE session from a Logout plasmoid), it's just another annoyingly extra step in the workflow from the menu option. Perhaps a good configuration may be to provide an option to skip the reconfirmation dialog in the scenario discussed above.

The level of incompleteness apparent in the 4.0 release has, unsurprisingly, drawn heavy criticism from end users here in our forums and elsewhere on the Internet. Several longtime KDE enthusiasts in Ars Technica's Linux community are particularly disappointed with the extent to which KDE 4.0 falls short of the promised vision.

I'm excited about the possibilities created by Plasma, Solid, and other new features in the KDE architecture, and I'm looking forward to seeing how they help the desktop evolve. I submitted a handful of bug reports while writing this article; developers responded almost immediately. If their diligence and rapid bug resolution rate is any indication, then I think we can be confident that future releases will meet or exceed expectations.

So I share the opinion with them, that kde 4.0 is for enthusiasts and early adopters. Having solid and innovative technical infrastructure help creating great software. Which I'm sure kde 4 will evolve into.

Jag har själv prövat OpenSuSE KDE4 Live CD genom VirtualBox och det finns mycket snygga grejer och finesser jag gillar men det är lite ostabilt än så länge. Dessutom kan jag inte ha allt lull-lull igång då VirtualBox inte klarar av det. Men som någon skrev i någon kommentar någonstans ( :P ) så är denna versionen egentligen till för utvecklare och för de som vill vara "on-the-edge" (om man nu skriver så?).

Mer KDE 4.0:

• Linux Tech Daily
• Ten Tips for KDE Beginners

Liten fotnot: VirtualBox är ett program som man kan skapa virtuella datorer med. Till exempel kan jag i min Windowsdator skapa en ny dator med hjälp av VirtualBox där jag kan installera ett helt annat operativsystem som i det här fallet var KDE-four LiveCD. Mer info.

Fast forward a year. Last week KDE 4.0 was released and there are a few things that are missing. We the users of KDE have lost options that we had in the 3.5.8 version of KDE 4.0. For example I can't figure out how to add another panel on the desktop. I can't even re-size the existing panel. The new menu system is horrible. There are a lot of Linux users complaining and there are as many Linux users defending the new KDE 4.0. Last year the same was being said about Vista. I think that we are too fast at complaining, we want instant results. I have been playing a bit with Vista and it is not as bad as everybody says it is, there are a lot of stuff I don't like about it but there is some that I like. With that said I would not choose it as my OS.

KDE 4.0 is a stepping stone for greater things to come. If you are switching from Windows or Vista to Linux and you want to work with KDE I strongly recommend you go with KDE 3.5.8 for now and hopefully within a year KDE 4.1 will be out and will have a few of its annoyances worked out.

I have to say to the KDE 4.0 developers you can't satisfy everybody all the time, we end users are bastards, when something is not to our liking we will complain until the cows come home and when it works fine we usually don't say a word. I would like thank all the developers of KDE 4.0 for all your hard work and dedication to the cause of free open source software, keep up all the good work.

Edit:  I've added in the comments a link to a tentative releases schedule for KDE4.  I did not have this information when I wrote this post.

1. Το πρόβλημα με τα ελληνικά και τα διαφορετικά παράθυρα παραμένει! Εξηγούμε, στο GNOME αλλά και στα Vista (Windows γενικότερα) είναι δυνατό σε ένα παράθυρο να έχεις γυρίσει το πληκτρολόγιο στα ελληνικά και σε άλλο να γράφεις αγγλικά, πχ να μιλάς στο pidgin (msn) στα ελληνικά και παραδίπλα να γράφεις python. Στο KDE ΔΕΝ γίνεται αυτό από πάντα! Είναι το πιο σπαστικό και πραγματικά μου τη δίνει!
2. Λείπει (;;) quicklaunch στο taskbar. Επίσης δεν μπορώ να καταλάνω πώς στο καλό ρυθμίζεται το μέγεθος του taskbar μιας και το δεξί κλικ απάνω της βγάζει άλλα 'τν' άλλων... Επίσης ΔΕΝ υπάρχει show desktop κουμπί (;;;) και στην επιφάνεια εργασίας τα εικονίδια σα να μη στοιχίζονται με τους κλασσικούς τρόπους (μέγεθος, τύπος, ημερομηνία).
3. Ορισμένες γραμματοσειρές (fonts) δε δείχνουν τόσο συμπαγείς όσο σε GTK+ εφαρμογές. Επίσης UI εφαρμογών όπως firefox και thunderbird δείχνουν "παλιά" και"τετραγωνισμένα".
4.  Επίσης GTK+ μάλλον δεν έχουν applets ώστε να γίνονται minimized όταν πατάς το κουμπί [Χ], έτσι πχ το pidgin κλείνει αντί να ελαχιστοποιείται.

Αυτά από την πρώτη μέρα. Δεν ξέρω αν τα παραπάνω είναι παιδικές ασθένειες (αν και το πρόβλημα με τα ελληνικά ΔΕΝ είναι) αλλά ελπίζω να διορθωθούν. Προς το παρόν KDE 4.0 αλλά δεν ξέρω για πόσο θα αντέξω και θα γυρίσω πίσω στο GNOME :-)
