power management & cpu scaling

[jhewer]

hello,

i was wondering where i can find out more about power management and cpu scaling in feisty?

i'm currently using edgy on a VIA Eden7 based system which supposedly supports CPU scaling through acpi-cpufreq, however I could never get this to work with edgy

i'm wondering whether it's worth installing feisty in the hope of getting cpu scaling to work, or not?

thanks
jon

Re: power management & cpu scaling

story:
i installed feisty beta on a separate partition to test the power management features.
all was good.
with feisty beta i could suspend, hibernate and resume my laptop allright (it didn't work with edgy).
so i waited for feisty final and upgraded my edgy.

result:
suspend, hibernate and resume still don't work.
not with the default power manager at least.
i installed uswsusp and i can have s2disk and s2ram work all right.
cpu scaling works ok though.
i have set it to performance when on mains and to dynamic when on batteries.
no complaints there.

my experience:
if you can, do a fresh install of feisty.

hth
cheers

thanks for the info. if i do decide to switch to feisty, i reckon i will do a clean install having read a bunch of problems people have been running into over in the installation forum.
