[KLUG Members] Laptop Linux users

[Buist Justin]

While we're talking about increasing battery life... I've got my laptop set to spin down the hard drive when it hasn't been hit for 5 minutes.  Works great in console mode -- but something when I'm running gnome or kde keeps insisting it needs to touch the filesystem and I have no idea how one would go about tracking down such a program.

If I can find 'em I'd very much like to try and cleanup the code so that it's not hitting the disk when not necessary.  One thing I learned when doing the ACPI stuff was that doing an open() call on /proc/acpi/battery/0/status or whatever would cause a disk hit even though /proc is a non-disk directory.  Keeping the fd open though dup()ing it and seek()ing back to the beginning would let you re-read the file though w/out that disk hit.  Little tricks like that scattered about the core gnome apps might do a lot to keep the battery running a lot longer.

So, anybody know how I can ask my OS what in the world is touching my disk?

Thanks,

Justin Buist
