------- Comment #12 from rui.zh...@intel.com 2008-12-18 17:50 ------- First of all, it seems we can not control the backlight via ACPI video unless there is a BIOS fixup. Second, the fujitsu driver can not catch the hotkey events, can it? If it can, that's great, if not, there is a acpi notifier chain which can sent out the hotkey event, can this be used by the fujitsu driver? I mean, in case the acpi video backlight interface doesn't work while the platform driver works, we can: 1. disable the acpi backlight control function by "echo 0 > /sys/module/video/parameters/brightness_switch_enabled" 2. platform register an acpi notifier 3. when hotkey pressed, platform driver get the notification and changes the brightness. -- 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. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
