Did yours also get notably worse as your updated the OS, or has it always been this bad? My left nub these days seems to want to go left and down more than it ever wants to go right and up, and I don't recall it being that bad when I first got my unit, but I can't peg it down to a particular update that made it worse. The nub dance does usually work for me, although rarely for very long.
My left nub is usually working well after I reboot and log on, it then rapidly stops going up and right within the next few seconds. A keyboard shortcut to reset the nubs may indeed be useful for when I really need to use the nubs, although I've learned how to do almost everything using the terminal for now, and always have one of those running somewhere (or can get one using the pandora button, the d-pad down (twice, I think), and enter relatively quickly). But if that shortcut would work from inside full-screen games, that might enable me to play some that I've stopped having to play for now.
