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.
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
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
kde-plasma-desktop is just
plasma-desktop in 16.04.
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
