aptitude install powertop powertop On most recent CPUs - the CPU goes to sleep and consumes much less power. > > Even if watching a movie, a good video driver will shuffle as much as > possible to the GPU, reducing the *effective* benefit.

The above run of aptitude involved quite a few checksumming operations. -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il | | a Mutt's tzaf...@cohens.org.il | | best ICQ# 16849754 | | friend -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
