Most people who want a user-replaceable screen just buy a Thinkpad. I've replaced the screen on all two of the thinkpads i've owned over the last 16 years. I still have my X series from 2010; it still works, only an ant crawled between two layers of the screen and died near the center and after 7 years it was time for an upgrade. It also ran (still runs) linux just fine due to that one guy at RedHat (who very recently retired) who maintained so many of the drivers for the world. I never needed anything more complicated than a philips head screwdriver to replace the screen, ram, keyboard, hard disk, or battery. And you can get parts for a thinkpad in most countries you're likely to visit.
