    Hi ya'll,

    I'm curious - why does the current Ubuntu wiki not recommend turning on:

    ENABLE_LAPTOP_MODE=true

    In /etc/default/acpi-support?

    It seems that when I turn this on that it is properly switching all the kernel/vm params to values very similar to that in the wiki when entering sleep, but then kicking things back up to high performance when on AC. (As verified by running sudo laptop_mode status).

    Tried it out...Seems it does a great job of scaling the processors down, but does not allow them to kick in when needed. Games run at a crawl because they are at 800mhz. Once I turned it back off, the games ran fine. It also seemed EVERYTHING was SLOOOOW. Even simple tasks such as file browsing was at a crawl pace. And my battery life was not affected much at all, it's not like the atom uses that much power in the first place.
