After using my Pixelbook Eve on Ubuntu Eoan (19.10), my Ubuntu has started notifying me for an upgrade to 20.04 LTS. So, based on my past experiences of Ubuntu upgrades and how they always break things, I went through the process of backing up my files and making a Clonezilla image of my Pixelbook before even starting to do anything.

Then I went through the upgrade. It went through without any problems, but when it went to reboot afterwards, I was black screened after the Ubuntu splash screen.

I suspect it’s because my Pixelbook contains some tweaks via this GitHub repo, and that is still using a 4.x kernel. Last update was in 2019, so maybe it’s out of date.

Before restoring my old image back on, I installed GalliumOS which is an Ubuntu-based distro specifically aimed at ChromeOS devices. Then made a backup image of that before restoring the old image back on.

I might try installing Ubuntu 20.04 from clean and see if that has any better Pixelbook support than the older versions of Ubuntu, and make it so I don’t need to use the hacks. Bear in mind the hacks used the ChromeOS kernel, and I couldn’t do some things like use ufw or gufw. Using GalliumOS should fix that since I wouldn’t be using tweaks.

However, there’s still an annoying quirk GalliumOS has on my Pixelbook and that’s the jumpiness of the mouse pointer — touch the touchpad and the pointer jumps to that part of the screen, as if the touchpad was a representation of the screen, not a touchpad. It’s a quirk that can be gotten used to, but it is still annoying.
