Ask HN: Simple Linux Machine

Is there an SBC that just works and works well with the Linux kernel?

I’m looking for something low in price ($100-$200) with mainline kernel support. I hope for stable and accelerated X11 with video and sound playback. I’d like to be able to drag windows around at full frame rate.

Architecture doesn’t matter.

I’ve been trying really hard to get Pine64’s RockPro64 to work as a nice little dev / office-work machine. It just doesn’t seem to be working out. Manjaro (Arch) Linux on multi core ARM, even at 1080p on a ARM’s Mali T860 GPU, is just not smooth at all.
