Hi, I'm using v2.6.31-rc1-228-g2bfdd79 and Debian's xserver-xorg-video-intel 2:2.7.99.901-2 when using kms xbrightness doesn't find a brightness property for any display (LVDS connected only). Without kms everything works fine. Chipset is: (II) intel(0): Integrated Graphics Chipset: Intel(R) Mobile Intel® GM45 Express Chipset
It's a known issue for KMS. *** This bug has been marked as a duplicate of bug 20963 ***
