I got lubuntu running on an apollo lake celeron Chromebook from 2020 with 4GB of ram and a 32GB eMMC drive. For the most part it does pretty well with web surfing, email, document/spreadsheets etc. There is quite a bit of delay (on the order of a minute or two) when using Discover to update anything, or to even browse the store. I don’t know if that’s due to lubuntu not loading discover when the Chromebook boots up for some reason or that the eMMC drive is really that slow.
I have a 128GB micro SD card in it as well that I am trying to set up as the main drive location for Discover to install things to, but it’s giving me some issues.
I haven’t tried any gaming yet, because of the micro SD card issues, but once I get that figured out, I plan on installing Heroic Games Launcher, and then installing some lighter weight games, I have RCT3 and SimCity 2000 in my GOG library, as well as the original 1993 Myst and 1997 Riven games. I think all four of those should run okay, but I’m not sure what overhead WINE/Proton will add to the mix.

No self respect.
