Brightness on 330M - Sony Vaio z11z9 notebook does not work even with 2.6.35-rc3
Brightness does not work on my Sony Vaio z11z9 notebook with 256.35 driver on all kernels including the latest one 2.6.35-rc3. I can modify brightness using 'echo -n', but it does not reflect any visible changes. I'm still using workaround by modifying green-red-blue colors using nvidia tool - 'nvidia-settings -l'. The same sort of things happened with my Sony Vaio TZ1 notebook. But it was fixed using linux NV driver instead of NVIDIA one.
Could you please provide me with any description why it happens for all new video cards and when do you fix this sort of things at all?
