GNOME comes preinstalled with a battery app(right click on panel, click add to panel, and choose Battery Charge Monitor). However, when I click on it I get the following error message.
Can't access ACPI events in /var/run/acpid.socket! Make sure the ACPI subsystem is working and the acpid daemon is running.
Checked in the kernel (2.6 series), and most everything is selected. Can someone point me in the right direction.
