Evgeny,
Please attached the lspci output.
thomas,
there are two ACPI video buses in this laptop. GFX0 AND NVID.
IMO, GFX0 is for integrated Intel graphics card.
It's weird that IGD bios code is implemented in the BIOS but noone will invoke
this piece of code, while usually GDCK/GLID/GHDS should be invoked in _Lxx.
Plus, there is only one _BCM method available in this BIOS, and it's located
under NVID.LCD, which means that no brightness control available for any ACPI
video device under GFX0...
This bug seems to be a duplicate of
http://bugzilla.kernel.org/show_bug.cgi?id=9939
So, as thomas suggested, I think acpi_osi="!Windows 2006" may help on this
issue. Evgeny, please give it a try.
