Suspend on low battery

[Stuart Bishop]

If there is a way to configure my laptop to suspend when the battery is low, I'm
unable to find it in the System menu. Currently it only seems possible to get a
popup alert when the battery is running low. Ideally we need to be able to
configure actions when the battery is 'low' (eg. popup a warning) and also when
'critically low' (eg. suspend to RAM).

Lack of this feature has caused me loss of work more than once at Ubuntu
conferences when I've tried to squeeze in just a little more typing before
searching for a power socket.

Perhaps gnome-power provides this?

[Oliver Grawert (ogra)]

yes, gnome-power is supposed to provide (suspend/hibernate/shutdown/reboot)
choices for:

- lid closed
- powerbutton pressed
- suspend button pressed
- battery power critical

sadly the current version i have packaged for dapper seems very broken :/ and
upstream insists that hal must
run as root ... (with --retain-privileges enabled)

gnome-power-manager is now a dependency of ubuntu-desktop and has this functionality
