Using old window decorations

2026-06-14_00-33

I want to use this window decoration (I believe it is called “keramik”?) on the latest/current version.

Is there any way to do this, I couldn’t find it in the downloads of windows decoration settings.

Note: I am using Ubuntu 26.04 LTS/Plasma

That’s KDE 3.1 Keramik style. It’s from like 24 years ago. You’d need to port it to the current KDE Plasma. Probably doable, I could probably look into porting it some day as a personal project.

Some more info:

Keramik was nice, I was also a big fan of Fahrenheit

I was looking at this, but I can’t quite figure out how to set it as a window decoration (1. as I don’t know the differences between old/modern decorations and 2. as it doesn’t seem to let you insert from file?)

You can try

kpackagetool6 -t Plasma/LookAndFeel -i NameOfFile.tar.gz or point to the folder

To install from file but I’m not sure if it’ll work, broski

Also, the difference between old and new Window Decorations mainly comes down to the code, the APIs they used, the syntax and everything, it’s been 24 years since Keramik so of course it’s not gonna be compatible with the new version of plasma I mean 6.5 and 6.6 have major differences already in terms of customization of widgets and such since before 6.6 you could customize the plasmoids more easily but 6.6 introduced compiled widget code where you have to create your own widgets instead of overwriting the existing ones which I thought might be tedious and less accessible for users to mod at first but honestly not really you can still do your mods

Could this be dangerous to run (or to select if it loads in properly)?

Probably not. If you have doubts run it in a VM

Apologies for the long time, I’ve been busy.

I did:

berilly@berilly-surfacego2:~/Downloads$ kpackagetool6 -t Plasma/LookAndFeel -i keramik
qt.dbus.integration: QDBusConnection: error: could not send signal to service "" path "/KPackage/" interface "org.kde.plasma.kpackage" member "packageInstalled": Invalid object path: /KPackage/
Successfully installed /home/berilly/.local/share/plasma/look-and-feel/keramik/

yet it doesn’t appear on system settings under window decorations (even after sudo reboot)

Yeah looks like it’ll need to be properly ported. Might do it myself some day
