I'm using my PBP with the original mrfixit Stretch, and X. I noticed that sometimes the mouse (touchpad) pointer gets stuck. Often I can't find the mouse pointer just because there are places it's an I-Beam which isn't very visible. If it gets stuck in one of those places it takes a while to find it.
I've done a little xlib programing so I know that there's a stream of events constantly (almost) being processed. See man pages like XtNextEvent, XtPending, XtMainLoop. I suspect something's causing these to not get cleared fast enough at times. If my cursor won't move I just let it sit a minute and then it works again. Sometimes more down pressure helps a little but not much.
