[solved] power management without HAL and pm-utils

hi guys! i got rid of hal and pm-utils, but i'm having some troubles now with the powersaving settings.

i'm using hibernate-script with uswsusp tools to hibernate etc, and laptop-mode-tools with acpi for the power management, but this looks like it isnt working anymore.
for example the screen backlight wont shut down anymore when i close the lid, despite the acpi action scripts are all ok.
far more importantly the cpu fan doen't ever start!! earlier this morning the cpu hit 77°C (while it's normally 40°) but the fan didn't kick in!

what can i do?

EDIT:
wait, maybe it's just the new kernel i've installed this morning! it's some days now that i've uninstalled hal and i think i would have noticed before!

disabling laptop-mode-tools temporarily solved the problem. i mean the fan is now spinning free ^^

i'll try reinstalling it or downgrading the kernel later

Re: [solved] power management without HAL and pm-utils

it was just some bad settings in laptop-mode-tool (which seems to work only if automodules is enabled. manual configuration won't).
