------- Comment #25 from [EMAIL PROTECTED] 2008-01-09 06:14 ------- There are three things that come to mind which would stop ACPI video.c to change brightness by itself: 1. ACPI video.c bugs 2. X.org has been loaded and told either ACPI or the BIOS itself to not do it (I don't know if it must be *active*, btw. Maybe it doesn't undo it on exit or display switch) as it can program the Radeon BIOS scratch registers in a way that the BIOS looks at it and decides not to touch the hardware 3. ThinkPad firmware bugs. Do test how it reacts when you tell the ACPI firmware to let a query for an OSI of "Linux" work or not, and report that back, because we now have a way to ask Lenovo to change that if needed. I forget which kernel command line option does this :( -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
