KDE neon is a Linux distribution developed by KDE based on the most recent Ubuntu long-term support (LTS) release. It containing the latest 64-bit versions of the Plasma 5 desktop environment. Now it is rebased with Ubuntu 20.04 LTS.
The distribution is focused on the development of KDE. The emphasis is on bleeding edge software packages sourced directly from KDE and offers programmers early access to new features, but potentially at the cost of greater susceptibility to software bugs.
The user interface is clean. You will find KDE Plasma 5.19.4 installed on it. To manage your files, it comes with the Dolphin File manager. It is pretty efficient to get things done faster without missing out on any feature for the most part.
Now, VLC Media Player comes baked in with KDE Neon. You wouldn’t need to install additional media codecs to play most of the videos. In addition to VLC, there are several useful apps pre-installed that includes a screenshot capture utility, emoji selector, Firefox browser, wallet manager, KDE connect and system process manager among others.
Differences between KDE neon and Kubuntu
Because Kubuntu has the KDE Plasma suite on an Ubuntu base OS, KDE neon often is mistaken for Kubuntu and vice versa. However, the primary difference between the two operating systems is that Kubuntu maintains stable releases and LTS version of Ubuntu while KDE neon focuses on updating developer editions of KDE applications without maintaining stable releases of Ubuntu unless the root user actively chooses to upgrade their systems.
To conclude, KDE Neon is a great distribution if you like Plasma 5 desktop and Ubuntu base, but you need to spend quite some time to set up and configure it. Not as much as you would spend with Arch Linux, but still a sufficient amount of time.
