------- Comment #7 from [EMAIL PROTECTED] 2008-10-20 15:05 ------- Hello, I can confirm that _BQC is always = 0. I added some printk() calls to a test kernel last week. The process that reads /proc/acpi/event is acpid. I rebooted with all daemons disabled, and it made no difference. There are no video related actions in my acpid configuration. It is only used to suspend the laptop. After booting, the value of /sys/class/backlight/*/brightness is 7 (maximum), and the value in /proc/acpi/video/VGA/LCD/brightness is 100. Using the brightness functions keys, the brightness of the monitor obviously changes, but the values in those 2 files remain at maximum. If I echo a different value into either of those files, both the brightness and the value change, as they should. Switching to console or returning form xorg screen blank set the brightness to maximum, but the values in the 2 files remain unchanged. Example: 1) After boot, screen is at 100% 2) I do "echo 62 > /proc/acpi/.../brightness". Screen brightness goes down, and the brightness file contains the correct value. 3) I switch to console using Ctrl+Alt+F1. The brightness goes to 100%, but the /proc/acpi... file still says 62%. I hope I've given you all the info you need. Thanks for looking into this.
