 # Linux on a Dell Chromebook 11

+NOTE: Last time I saw the Dell Chromebook, it was on a pile of electronics bound for the county recycling center. The N3060 CPU's 2 cores were just too sluggish for it to be usable during that overseas trip mentioned below. I leave this gist here mostly out of nostalgia.
 
 My retail (not enterprise) Dell Chromebook 11 (an Inspiron model 3181, not the 3180 or 3189) went EOL shortly after I purchased it new from Best Buy. Since then it saw some hard use in the family kitchen as a recipe lookup device, but was finally retired when replaced by a (relatively) newer Android tablet (that also reached EOL shortly thereafter).

-After some research, I decided to go against all advice and install Ubuntu 23.11, whose kernel was just new enough to support MrChromebox's firmware. I used Ubuntu's "Startup Disk Creator" (a/k/a [USB Creator](https://launchpad.net/ubuntu/+source/usb-creator)) to install Ubuntu 23.11 on a usb stick and then selected it from the new UEFI menu.

+After some research, I decided to go against all advice and install Ubuntu 22.04.01, whose updated kernel is just new enough to support MrChromebox's firmware. I used Ubuntu's "Startup Disk Creator" (a/k/a [USB Creator](https://launchpad.net/ubuntu/+source/usb-creator)) to install Ubuntu 22.04 on a usb stick and then selected it from the new UEFI menu. During install I was careful to select "Minimal installation", "Download updates while installing Ubuntu, and "Install third-party software". This insured that I'd have latest kernel and firmware, and minimized the amount of bloatware I'd have to remove after setup.
