There is a Thinkpad (x12) that has a detachable keyboard. Thinkpads usually play nice with Linux, but I can’t speak to that model specifically.

Fine details blur less, or at least more slowly, with ink around them. So might be a good idea to have a halo of white or some other color around the letters, or perhaps have them all in a tasteful frame of a more subdued color. I also agree with the other comment that you may want to save up to have an experienced artist do the piece; a more practiced hand will get the lines crisper and do less damage, which will help them stay better longer.

I would think it should be in the boot log, but I am unsure on that one.

Sounds like that shutdown the system, so the problem is just getting it to power off. You could try "halt -p”. That explicitly calls for the system to power off. If that doesn’t work, perhaps try “halt -verbose”, which will give a bunch of info on the next boot about what halt was doing, might show an error there that could you lead you in the right direction.

Did you use any arguments with shutdown? Does shutdown spin down the system, but not turn off the hardware, or does it not do anything? You can try " shutdown now -h". That should halt the system after a graceful shutdown.
