I’ve got it installed on a Debian 12 box I’m using as an htpc. It’s works pretty nicely.

I tried it and I don’t think it’s usable. the applications it has are quite frankly garbage. and it overall feels janky to control. not great IMO

One of the pages on the site you’ve linked mentions Debian having Plasma Bigscreen in the package repo, so I imagine you can just download it on anything that runs the right instruction set. (armv7, amd64, etc. I am not sure what the package is built for.)

I’m going to find out if I can install it on MX debian with KDE when I get home.

Are u trying to install on x86 or ARM? ARM has images u can use. As for x86 I didn’t find distro with out of the box bigscreen configured, however there are AUR recipes - makes it easy to use it on Manjaro.
