Zhang Rui <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |NEEDINFO CC| |[email protected] --- Comment #8 from Zhang Rui <[email protected]> 2009-11-24 01:44:31 --- there are two problem here: No.1. the backlight control problem I checked the DSDT and it seems that there are Backlight control methods for device 00:01.0 and 00:02.0. but 1. _DOS is missed for pci 00:01.0 device 2. there is no pci 00:02.0 device This explains why /proc/acpi/video/ is NULL. But anyway, I don't think this is an ACPI problem. that's because you're using nvidia graphics on this laptop, which means that ACPI table doesn't have the backlight control methods for this device, i.e. backlight can not be controlled via ACPI. IMO, this is a nvidia graphics problem. No.2. the hotkey problem could you please attach the output of "grep . /sys/firmware/acpi/interrupts/*" both before and after pressing the hotkey? -- 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.
