Default KDE is not running good on my PC and it's too slow. I switched to Unity-2D and it's better. Wanted to ask if there is a more simple, lighter KDE that would work better on my PC.

Do you mean KDE? Unity-2D is not KDE at all its Gnome. There are other desktops too such as "Gnome Classic", "Xfce" which is used in Xubuntu and "LXDE" as used in Lubuntu. If you want to know about other non KDE desktops edit the question to say desktop instead of KDE and we can include these. –  Warren Hill Apr 18 '13 at 14:47

You should take a look at KLyDE and follow it's development. –  FSMaxB Apr 19 '13 at 13:32

I would definitely recommend installing the "kubuntu-low-fat-settings", which removes a lot from the default kubuntu-desktop installation. KDE will be much lighter after that.

However the low-fat-settings may also remove some thing which you need.

Some of which are:

  • Turns off compositing by default
  • Reduces the number of Krunner plugins loaded by default
  • Reduce the amount of effects used in the window decoration
  • Disables the automatic loading of various system modules – such as the free space notifier, Nepomuk services, and others

See this article for more info: http://www.omgubuntu.co.uk/2011/09/kubuntu-low-fat-settings-speed-boost-older-hardware

RAM and CPU/GPU usage will be dramatically reduced by installing this package

To install the package simply run this command:

sudo apt-get install kubuntu-low-fat-settings

So at first i need to install normal kubuntu and then over it to install this "kubuntu-low-fat-settings"? –  Moshe Kerbel Apr 18 '13 at 14:37
    
Yes, exactly :) –  Steffen Christensen Apr 18 '13 at 14:39

Yes you do have an option here.

If you install kde-plasma-desktop then it will gives only core of KDE and nothing else.That is the final possible light weight KDE you can get.

to install that open your terminal and type as

sudo apt-get install kde-plasma-desktop

Then from the log-in screen you can choose your Session.

For more information Ubuntu-KDE

Maybe you are interested in Razor-Qt. It's not KDE, but a very lightweight desktop based on Qt, the same framework KDE is based on.

Note that it has a more lightweight approach than Xfce for example, which can be good or bad, depending on what your needs are.

You can install it via PPA:

  • sudo add-apt-repository ppa:razor-qt/ppa
  • sudo apt-get update
  • sudo apt-get install razorqt
