I did as you advised, but:
i. when I do `kldload acpi_asus` sysctl hw.acpi.asus.lcd_brightness is
"1"
ii. fn+f5,f6 still doesn't work...
I hope this helps:
notebook# sysctl hw.acpi.verbose=1
Fn+F5: Feb 10 13:40:48 notebook kernel: acpi_asus0: Brightness decreased
Fn+F6: <no any messages>
after 1st Fn+f5 value of hw.acpi.asus.lcd_brightness is 14.
I can press 'Fn+f5' many times but value doesn't change.
Fn+F7: Feb 10 13:41:27 notebook kernel: acpi_asus0: LCD turned off
Fn+F7 again: Feb 10 13:41:28 notebook kernel: acpi_asus0: LCD turned on
