@John Haitas: Maybe I should clarify a few things. (1) The original bug report mentions smartdimmer, Nvidia, and Geforce. Thus, the bug seems to be related to Nvidia graphics. The driver nvidia_bl in the mactel repository, which isn't specific to Apple machines, it is just there, might help. As well as the mentioned X.org option (EnableBrightnessControl) which is to be used with the Nvidia proprietary graphics driver.
(2) Your machine (MacBook4,1) incorporates an Intel graphics adapter. So the suggestions obviously won't help. (And pommed isn't necessary, but useful anyway.) For your machine, you might try mbp_nvidia_bl instead. This one is Apple-specific, but despite its name not restricted to MacBook Pros. Afaik, the upstream version (and thus, karmic and lucid) doesn't support your machine yet, but my patches have been accepted recently, so it might work when lucid gets released. In the meantime you might try the patched version in present the mactel PPA. (3) Finally, what's this report about? Nvidia? Intel? ATI? Device Kit? ciao, Mario -- no backlight support for laptop (hal depreciation regression) https://bugs.launchpad.net/bugs/385723 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support.

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 !
