Revision c9e75b2125b563e67663f78ad53ea9387a9a7aa1 authored by Alex Deucher on 02 June 2010, 21:56:01 UTC, committed by Dave Airlie on 07 June 2010, 23:35:19 UTC
This adds an additional profile, mid, to the pm profile code which takes the place of the old low profile. The default behavior remains the same, e.g., auto profile now selects between mid and high profiles based on power source, however, you can now manually force the low profile which was previously only available as a dpms off state. Enabling the low profile when the displays are on has been known to cause display corruption in some cases.
