As I posted last year, KDE 4 is my favorite. Surprisingly, Kubuntu 20.04 brings the legacy Oxygen theme built-in. Thanks to Gemlog on social media, I discovered it. Now I bring you how I do it.

Final Look and Feel

Results first! There are my Kubuntu Focal machine with the legendary Oxygen theme I loved so much. It is amazing I can still enjoy this look and feel once again after eight years.

(Plasma 5.18 with shiny metallic looks once again thanks to Oxygen icons –at backgroundOxygen folders –on file managerAir translucency –the clock and panel– and overall everything is like 2020 travels back to 2012)

(Translucent start menu and tray and their shining icons once again my favorite)

(Metallic right-click menu with its smooth drop shadow)


Here’s what I did to get Oxygen look and feel:

  1. Go to System Settings.
  2. Switch  Plasma Style to Air.
  3. Switch Application Style to Oxygen > Apply.
  4. Switch Window Decorations to Oxygen[1] > Apply.
  5. Switch Icons to Oxygen > Apply.

(System Settings at Window Decorations section selecting Oxygen only appears after you install it from package not from *Get New Window Decorations button)

[1] You need to manually install this one package before doing so:

$ sudo apt-get install kwin-decoration-oxygen

Enjoy Kubuntu Oxygen!
