[EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[EMAIL PROTECTED] ------- Comment #53 from [EMAIL PROTECTED] 2008-03-20 15:50 ------- Zhang, this bug scares me a little. It sounds like the OpRegion based interface is correctly giving us hotkey notifier events, but not giving us a way to actually change backlight levels. Is there a separate set of ACPI methods we need to use to actually change the backlight brightness? Are we supposed to use the LBB & BLC_PWM_CTL regs? Won't that conflict with the external controller in these machines? I think you and Hong have tested this on T61s, so I'm curious to hear what you've found... -- 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. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
