I havent done more than cursory search so if somebody mentioned this before, not trying to steal your thunder. https://www.how2shout.com/linux/how-to- ... 20-04-lts/
Had no idea it offered this option. Mostly got to looking at linux kiosk mode distributions after playing with Chromebook I got for total of $12 plus tax on Ebay. Thinking ChromeOS is lot like kiosk though I have no use for a kiosk. I am guessing they made nothing after paying shipping. Its in nice enough shape, three little bright spots on screen, not that noticeable. no charger, and think the version ChromeOS is about expired. Not "managed" so going to eventually try putting Puppy or Easy on it as only OS. Should be powerful enough, has 4GB RAM and 4core Celeron, but only 16GB eMMC. Battery seems good shape.
I am not sure I quite understand people paying significant money for a new chromebook, but after I got it online it was usable. I had to use create_ap to create a hotspot since I dont have wifi otherwise. And it would only use the hotspot connection in "guest" mode. Apparently a known problem with Chromebooks. Claimed no connection trying to set up google account, despite the wifi app showing it connected. not that I wanted to officially set it up with Google. Whats weird Mr. Chromebox only offers a live script to install new bios, cant apparently do it offline. So interesting to see if it can run the script via hotspot connection. Next step before new bios, have open it and remove the security screw.
I figured if nothing else, since its fanless, that I could use it as full screen clock. In guest mode it can only access files from external drive. Hey $12 isnt that bad for a clock. LOL
