I'm running the openbox WM and would like to avoid loading the gnome stack. One of the lingering issues I have to resolve is avoiding abrupt system crashes due to depleted battery power.
Is there a low-profile, low-dependency daemon that will handle this situation? I'd like to be able to configure it to, for example, drop the system down into hibernation at 4% battery life if the AC is not connected.
I suppose I could just write a little cron job to poll /sys/.../batt*/..
and /sys/.../ac*/...
every 10 minutes or so, but it seems like there might be some edge cases that need tending.
update
laptop-mode-tools
sounds promising:
It ... supports various ... power management features, such as ... automatically hibernating if battery levels are too low...
However, it doesn't seem to be possible to install it in Maverick without relatively dire consequences.
On my system, its installation also requires the removal of the acpi-support
package, which sounds sort of ominous.
