Debian Trixie headless on my router/server raspberry pi and NixOs on my laptop.
However I’m planning to switch from Nix this summer since one of the maintainers of NixOs is the one which added age verification to systemd, still haven’t decided on which Os I’ll switch to probably Devuan os but may give Alpine a shot since it’s more stable than Arch btw, so I’ll just be ricing and distro hopping this summer until I pick my new favorite again.
I used to love the minimalism of lxqt over xfce until I learned that QT is proprietary and GTK is open source, therefore I’m with now xfce for life.
