I have been. I looked for a while before I decided to ask. If there's anywhere in particular you think I should look, could you suggest it? I know how to do it on a Raspberry Pi, which is about the only on-board computer I have found with any decent amount of FRC documentation, but that's not really what I'm looking for. Thanks, and I apologize if I wasn't very specific.
[edit]
This is probably the most informative thread I've found, but it only briefly addresses the issue, with something like "We have a user that auto- logs in on startup and then runs a program in the .preferences". I guess I'll do a bit more research. Thanks
