frame.work also gets mentioned here from time-to-time as they support Linux [1], however reviews of the product itself are mixed, so this is not an endorsement, just an observation. I would read hn history and frame.work forum history before buying one for my use.

[1] "...Framework Laptop is working without issue in Ubuntu 21.04.3+ (NOT 20.04.3) and Fedora 35"
