--- Comment #11 from Lee, Chun-Yi <j...@novell.com> 2012-08-16 02:29:06 --- Hi Leon, (In reply to comment #10) > Created an attachment (id=77791) --> (https://bugzilla.kernel.org/attachment.cgi?id=77791) [details] > as above but without acpi_backlight=vendor There didn't have any acpi debug log in dmesg, I think your kernel didn't enable this config: CONFIG_ACPI_DEBUG=y Please check your config file in /boot if your distro put it there. And, per lsmod result, the acpi/video driver loaded on your system, it's match with your GFX0 in DSDT, just didn't show on dmesg. Please check your /sys/class/backlight again, there should have acpi_video0 folder. Per DSDT, there have _BCM, _BCL on GFX0 device, it's meet the requirement for a acpi backlight control device. If you still didn't see any folder show up in /sys/class/backlight, then please enable CONFIG_ACPI_DEBUG, we need check the ACPI debug log.
