The second Beta of the KDE Plasma workspace was released recently. Plasma 5 is the current development branch and Linux distributions shipping Plasma are in the process of integrating their desktop environment with this version. If you are a Kubuntu user, you can now test Plasma 5 easily. Kubuntu developer Jonathan Riddell says that most Plasma 5 packages have build successfully for Kubuntu and users can test it on their systems.
Before you follow my instructions to install Plasma 5 on your system, keep in mind that Plasma 5 is under heavy development and the stable release has not been made. Since it’s in development stage, there are (as expected) issues. Some of the issue you should be aware of include the missing wallpaper, icons may stop working now and then and Plasma Network Manager is missing as well.
So once you know what you are getting yourself into, go ahead and try it out on your test machine. You can actually help developer in finding the bugs.
