UPDATE 01:

Quick note for everyone following Margine: please report problems as GitHub issues from now on, so they all stay in one searchable place:

https://github.com/daniel-g-carrasco/margine-image/issues/new/choose

There is a short guided form for the ISO version, install method, Secure Boot state and logs. On an installed Margine system, you can also run ujust margine-report in a terminal. It collects all the useful information into one file.

Questions and general discussion are still welcome here. This is just for bugs.

Thanks!

After months of work, I’m finally releasing Margine OS, my own atomic Linux distro. The short version is that it’s fast.

It’s built on Bluefin DX, with Fedora bootc underneath, which means it keeps everything that already makes Bluefin good to use: it’s atomic, every codec is in place, updates happen quietly in the background, and you can always roll back if something breaks.

What I changed is mostly focused on speed. Instead of the stock Fedora kernel, it runs the CachyOS kernel with the BORE scheduler, re-signed with my own key so it still boots normally with Secure Boot enabled. The installer walks you through enrolling that key, so you never have to turn Secure Boot off.

Around that, there are a few things I had always wanted. You can switch sched_ext CPU schedulers live from a small GUI, with scx_lavd when gaming and plain BORE the rest of the time.

There is also a small tool I wrote, Wayland Scroll Factor, for adjusting touchpad scroll and pinch speed, which GNOME still does not expose. This matters a lot on the Framework 13, where touchpad scrolling is unusably fast without it.

GNOME comes configured for tiling out of the box with o-tiling, a fork of System76’s Pop Shell, together with Hyprland-style keybindings. Gaming is one command away with a native Steam and Proton stack, inspired by Bazzite.

The whole image is built, tested and signed through CI, and the ISOs are distributed torrent-first through the Internet Archive.

I benchmarked the kernel on the same laptop, a Framework 13 with a Ryzen 5 7640U, changing only the ostree deployment between Margine OS and stock Bluefin DX.

The results were roughly 1.8x faster context-switch latency, 54% higher thread throughput, and 43 to 55% lower median scheduling latency, with a small cost at the worst-case tail. This is the expected BORE trade-off. The full method and raw data are available on the site.

It’s a personal, opinionated project with a single maintainer, so feedback and criticism are welcome.

There is also an experimental NVIDIA variant that I cannot test myself, since I do not have NVIDIA hardware. If you use NVIDIA and want to help test it, that would be very useful.
