breath VS brcr-update

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

Use brcr-update (per https://github.com/BiteDasher/brcr-update) which is a script to update both the framework and ChromeOS.

But enabling automatic updates is said to be risky w/o a Brunch framework update, too. There is a script to do manual updates (https://github.com/BiteDasher/brcr-update) that was recommended, but I'm not sure if updating with that script has the same risks of new installs since they seem rather hit-or-miss. Instead of the script perhaps, just do automated updates until that breaks and then reinstall-til-it-works? I dunno.
