I used a pro 7+ for a while with Fedora on it and it ran just fine. The stylus worked generally well, too. Eventually I put Win 11 back on it to be able to use the camera (it was not yet supported by the linux-surface project and still may not be?) and it worked well enough with WSL that I kept it that way. I generally spent my time in firefox and windows terminal with little to no trouble at all (after de-clawing windows the best I could).

Note that the keyboard is about what you’d expect for such a flat thing. I’m pretty sure it’s rubber dome and not butterfly switches. It’s not a great experience but it’s no worse than your average laptop.
