This tutorial will help you using silver, metallic theme “Oxygen” that was popular in the era of KDE 4 on the modern Kubuntu 22.04 “Jammy Jellyfish”. In short, we will use Elarun as wallpaper and Oxygen as the rest of the whole themes including application style, colors, icons, Plasma style, and splash screen. All in all, we want to offer the best visual experience we had in the past to new generation of Kubuntu users as well as the long time users themselves especially those who appreciate nostalgia. Finally, we hope you will enjoy this!
