@tshirtman @mcc It wasn't clear how hard they were really looking. I just put Manjaro on a 2018 Samsung Chromebook 2 and it rules.
The process isn't simple, and involves software named like "Mr Bob's Chromebook Unfucker" - but, again, feels like a solvable problem.
@dulanyw @mcc maybe i should find such a machine for cheap (shouldn't be too hard if they are unsupported) to see how it goes, though it's unlikely to be better than even my aging thinkpad, so it would be more like a project than anything useful 😅. But good to know that there are decent solutions, it's quite sad to see working hardware get destroyed instead of being useful to people.
