I had two x86 tablets with linux, both with issues. Prev. owned a dell latitude 5285 and now a minisforum v3. The latitude maybe available for ~200 in secomd hand market but its quite old i5 7th gen is pretty slow today
Both had issues with volume buttons in linux, on the dell it worked when using x11 instead of wayland and for minisforum it was a simple change in config files.
For me it works, it took some tinkering (changing the video device). I can unlock my v3 after boot with my face.
