Making Qt5 style plugins available for Debian 13 (Trixie)

Publish Date: 2026-10-21

On one of my desktops, I run the Trinity desktop environment with the Plastik theme. For consistency with some newer Qt5-based applications, I also use the "Plastique" widget style via Qt5ct, which is a reproduction of the original "Plastik."

I'm running Debian 13 on everything these days and noticed that they failed to include the plastique, motif, cleanlooks, and gtk2 platform theme packages in the Trixie repo. Other than the gtk2 platform theme package, they still work on a Debian 13 system if manually installed. I mentioned this in my "Revisiting the Trinity Desktop Environment" post awhile ago with instructions on how to manually install them.

Since I'm running a Debian package repo, I figured I might as well use it for something useful and so re-packaged the missing qt5-style plugin libs. I don't know what all is involved with getting the gtk2 platform theme to work, but suspect it'll probably never work again.

Anyhow, here's the archive homepage with instructions for anyone interested. I'd like to put more software on it in the future, such as a GTK2 version of GIMP.

Available packages as of now:

• qt5-style-plugin-cleanlooks
• qt5-style-plugin-motif
• qt5-style-plugin-plastique

These expand the available widget themes in qt5ct.

Thanks for reading my blog!
