galliumos-skylake VS breath

My Chromebook uses a Skylake processor. So I went to https://github.com/GalliumOS/galliumos-skylake, cloned the repository using git and then copied the usr folder to /usr, etc to /etc and lib to /lib (all recursively). After that, I run the debian/postinst script with root permissions and rebooted.

After that, I tried applying the fixes from https://github.com/GalliumOS/galliumos-skylake for Ubuntu 20.04 and Debian 10. I copied the files to right directories and run the postinstal script as root. That didn't work. I realized I probably need a specific version of the Linux kernel. I installed Ubuntu 18.04 and did the same. It worked. Audio was working perfectly on Ubuntu 18.04 on kernel 4.15. Then, I tried upgrading to Ubuntu 20.04. I booted with the kernel 4.15... And the audio didn't work.

I tried applying the patches from the Gallium OS GitHub repo (https://github.com/GalliumOS/galliumos-skylake) on Arch Linux, Ubuntu (20.04 and 21.10) and Fedora (latest stable).

It disappeared without any visible explanations. Apparently, it was a a friendly fork of the Breath project (https://github.com/cb-linux/breath) by Apacelus (https://github.com/Apacelus/Apacelus). But Apacelus stopped working on it on May 26th (https://github.com/Apacelus/Apacelus/commit/c84ee94310144ec9...).

There's another project on Github with the same name: eupnea-linux-backup https://github.com/eupnea-linux-backup

As of now, audio on LARS works on GalliumOS Skylake out of the box and after some tricks on Ubuntu 18.04-based distributions and Ubuntu 20.04-based distributions. Furthermore, it may work on Breath Linux (discontinued).

Breath Linux might be you best bet - https://github.com/cb-linux/breath

Your best bet is probably the breath distro. It's not exactly Ubuntu, but it's probably as close as you're going to get.

I maybe wrong about this but few research on google suggest that sound isnt fully supported on that model, if its true then you may just be limited to Crostini, Crouton, Brioche or Breath https://github.com/cb-linux/breath but I suggest looking for someone here at reddit who had the same laptop and ask them if they have sound when running linux

Finally, there are packages like breath for more modern chromebooks that allow you to boot into native linux without flashing BIOS, but I haven't really tried using them.

But the actual difference can be achieved only with a dev mode rabbit hole. For example, you could try the Breath project that allows you to boot into Ubuntu from an sd card or a flash drive without messing with the system files. Since Ubuntu by default doesn't reserve so much RAM to itself, the games won't be begging for more ram and you'll see much better results. Everything said above is tested on a Celeron N4000-based 4GB Chromebook.

Did you see the site? There seems to be audio problems. https://github.com/cb-linux/breath/issues
