--- Comment #15 from Lee, Chun-Yi <j...@novell.com> 2012-08-21 03:45:17 --- (In reply to comment #13) > Created an attachment (id=78051) --> (https://bugzilla.kernel.org/attachment.cgi?id=78051) [details] > dmesg for a kernel with CONFIG_ACPI_DEBUG=y > Per your dmesg, even enabled acpi debug, I still didn't see any messages about Video Bus register. I think that because your video chip supported Intel OpRegion function, more detail need check your 'lspci -xxxnnvv' result. The acpi/video driver doesn't register when detected Intel OpRegion. I fully agree to Alan's suggestion in Comment #13, you should try gma500 driver in v3.5 kernel on your machine. If you just want to enable acpi/video driver for backlight control, another way is try to enable CONFIG_STUB_POULSBO in old kernel. But, I am not suggest it because this config will remove in the end of 2012. I still highly suggest follow Alan's suggestion, try the gma500 driver in v3.5 kernel. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
