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.

There are a lot of older, competent dual core machines available on Amazon very cheaply too. These are much cheaper but if you ever needed even one virtual machine it would be quite taxing. These machines are 4 or 5 years old so linux support is likely excellent.

These aren't strictly "SBC" but they're very similar. Basically laptop motherboards and soldered chips with potentially upgradeable storage/ram.
