------- Comment #39 from [EMAIL PROTECTED] 2008-01-24 12:46 ------- Zhang At first when I kill acpid I can control brightness both via /proc /sys and fn keys. So as I use debian unstable mabye problem not in kernel... There is many stranges in unstable debian now. >Weird, are you sure of this? YES! IN THIS FACT I AM SURE AT ALL 100% I check it in different configurations on two different lapop of the same model - toshiba U300-13M. Resume - _BQC method already return next not current level when I use fn keys! There is a sequence of brightness levels when I use fn keys to change brightness from the lowest to higest and to lowest level: (yoyr patch was applied to the vanilla .24-rc8 kernel, my patch wasn`t applied) MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 0 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 28 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 56 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 84 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 100 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 70 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 42 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 14 MISHA1:/usr/src# cat /proc/acpi/video/GFX0/DD02/brightness levels: 100 42 0 14 28 42 56 70 84 100 current: 0 2. echo 70 > /proc/.../brightness; 3. attach the result of "cat /proc/acpi/.../brightness" I have levels: 100 42 0 14 28 42 56 70 84 100 current: 70 and what we have from it? The echo xxx > /... works well since the _INI method was added. -- 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.
