I've had it happen, too. Feels like recently, but was probably a couple years ago, if not more like 3. I could never figure out how it happened. >From one reboot to the next, the value or values changed, but I had not *knowingly* done anything that should have changed it. By "knowingly", I mean via gparted which is the only place I've ever changed those manually. I've probably only done *that* maybe twice in five or six years, probably just to have done it to know how it would affect things. /etc/fstab was my go-to to see where things didn't match. Had a copy floating around just to remind myself whenever I stumbled back over it occasionally. I never thought to check grub.cfg before getting everything to match back up properly at the time. It hasn't happened since, and I've messed all kinds of other things up in the meantime... like killing my sound (again) about 2 days ago while trying to roll my own of something that I've already forgotten what it was. I think it was something about "that" dialup modem. :D Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with duct tape *
