Comment 34 for bug 385723

For me on sony fz, EnableBrightnessControl isn't working with the glx drivers...
The nvidia_bl isn't working for me (I tried karmic version, there is no lucid one), and in the description, it is supposed to support only NV40 and <, not NV50 like my geforce 8...

The report is about missing backlight support in ubuntu for nvidia glx. Nvidia won't do anything, hal either, so that ubuntu users are missing backlight control since 5 years, and there is no real solution for the moment...

Smartdimmer is now able to set and get backlight information for those cards, but is not yet used by ubuntu for backlight management. a nvidia_bl module is probably the right way, because devicekit is rejecting the idea to write a specific code to use smartdimmer for nvidia hw... But I think if on the side from ubuntu nothing is to be done, than ubuntu users will have to live without backlight support for again 5 years or more... and quite a lot of notebooks are shiped with nv hw.... not only mac but also sony, samsung, dell, acer...
