What's eating the battery life of my Linux laptop? Which software component causes the most power to be consumed? These are important questions without a good answer... until now. Intel announced the PowerTOP tool, a program that collects the various pieces of information from your system and presents an overview of how well your laptop is doing in terms of power savings. A number of apps, like Firefox, Evolution and Gaim have been modified by Intel to help consume less power and hopefully these patches will be integrated to their main trees or by distros.

Not ironic. XOrg has a broken DPMS notification system which is being fixed. If we don't poll X, then we currently don't know if the machine is in DPMS sleep or not. When we get the new API, we can remove polling completely.

Isn't it a bit ironic that the hall-of-shame list contains applications such as gnome-power-manager and S06cpuspeed - who's purpose, as I understand, includes saving power?
Oh, and the ibm-acpi module - required by IBM laptops to check battery, control LCD brightness, etc. - is there, too.
