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...

Bug description:
Binary package hint: devicekit-power

A lot of laptop have no backlight (brightness support) because of missing kernel support, and waiting for fix in hal...
In fact, the utility smartdimmer, in main repository, is providing everything need : a get and set method for backlight...

As hal will be depreciated, it would be nice, if it could be fixed in devicekit... and people having vaios, samsung and so could after a couple of years have full power management !
