[Guide] Comprehensive Linux Optimization for Chromebooks (BTRFS, ZRAM/ZSTD, Low-Write tuning)

Support Linux Support
1

I wrote a guide on how to configure Linux for the best performance on Chromebooks, focusing on RAM capacity and slower CPUs, and optimizing for eMMC/microSD storage.

I got a full-featured desktop Lubuntu installation using just under 5 GB of storage on my Chromebook, even with a full modern browser and desktop apps installed. (Mine has 4 GB of RAM, 16 GB of storage and a dual-core Celeron)

Most “optimization guides” out there are super old and use a ton of outdated advice, so I wanted to make something modern and actually effective.

I published the guide on GitHub and would love to hear how it works for you or answer any questions you have!

Try a distro named “MiniOS”

How do you leave the emergency menu after the first reboot?

Fixed. Messed up the sudo nano /etc/fstab thing

If you’re in emergency mode you can just click enter and then type in sudo nano /etc/fstab and see where you messed it up.

Cheers!

On all the chromebooks i’ve been using, there will be a bug where the speakers will eventually play a loud buzzing noise instead of any actual audio. Is there a fix for this?
