Learn the command to install the KDE Plasma desktop environment on Ubuntu 22.04 LTS Jammy using the command terminal.
There was a time when KDE was considered as a resource binger Desktop UI but not anymore, it is similar to Gnome in terms of performance but with a much beautiful interface and wide range of applications. It comes already as a default GUI in many Linux systems such as OpenSUSE, MX Linux, Kubuntu among others. The main focus here is on the many customization options.
Although the KDE desktop is beautiful, a bit more confusing at first glance, however as you start using the same, it is very reminiscent of Windows with its taskbar. This also contains the “Activity Manager” with which different desktop versions can be displayed, for example, to access a photo collection directly. The display of windows or the positioning of widgets – almost every element of the user interface can be customized in KDE. However, the variety of options can quickly overwhelm inexperienced users. You should therefore invest some time in your very own KDE experience.
Also, the applications from the KDE community are a lot more extensive and, like the KDE desktop, with a wide range of setting options. Great for power users, unfortunately often too overloaded for newcomers.
Well, coming to the latest Ubuntu 22.04 LTS version that also uses the latest customized Gnome version, however, if you using Ubuntu 22.04 minimal desktop or just want to switch from Gnome to KDE plasma, then here is the tutorial to start with.
