------- Comment #36 from [EMAIL PROTECTED] 2008-01-22 16:39 ------- I alredy have applied the patch in comment#11 (As far as I understand this patch is already in .24-rc8) With this patch I 1) can control brightness via /proc and /sys 2) I can`t use fn keys - theq does`t work Without this patch I 1) can not control brightness vi /sys or /proc (Only can see current value, but I can not set it) 2) I can use fn keys In comment#32 I have post some piece of code that allow me to use fn keys and to control brightness via /proc (not /sys) in the same time. On my machine there is two problems with video.c acpi driver, when patch from comment#11 installed: 1) When I press fn key acpi_video_device_notify() with right event. So sequence fo brightness correction called and brightness changes. BUT when from acpi_video_device_notify() calls acpi_bus_generate_proc_event() something hapens and, as result, acpi_video_set_brightness() calls with previous value of brightness. As result nothing happens with brightness. And fn keys doesn`t works. I have traced all this calls, by addin printk functon. I can`t understand where is there acpi_video_set_brightness() call with old value of brightness. I simply disabled this call in my patch, by changing function parametr. This is not a good idea. 2) When video.c calculates next brightness level on my laptop it does it not in right way. The _BQC method already return next not current level! So it skip some levels. I don`t know is it bug of driver or of my notebook... In my patch I have fixed this for me. I don`t know how it will be work on different machines. >For issue 3, please make sure the value you set must be one of those gotton from /proc/acpi/video/GFX0/DD02/brightness. Yes it is from the list. -- 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.
