I wouldn’t say it’s excellent, but I do my best. I’m constantly researching ways to increase it, if you offer an strategy.

Here, on an iMac 11,1, the code compiles and runs and has an effect, for brightness levels 0 through to 15, but brightness level 0 is some way above the lowest brightness set by Mac OS X. If I set the brightness to minimum in Mac OS X and then boot to Ubuntu, I get what I want. It is as if there may be another port for the scaling factor.

Here, on an iMac 10,1 (21.5″, ATI Radeon HD 4670), the code compiles and runs but has no effect.

Ok, I’m back. I managed to adjust the brightness through the compiz setting manager application (install compizconfig-setting-manager from synaptic). I have maped my brightness keys to do the job although this only works for active aplication. If you find a way to make it work for the whole system please let us know.

Hello,
I’m running ubuntu 10.10 on iMac 24″. Compilation of the code was successfull, but then when I run the code, the returned current value is ok, but the brightness is not changed… See:

$ sudo ./a.out
Current value : 15
$ sudo ./a.out 10
new value: 10
$ sudo ./a.out
Current value : 15

This thing is still killing my eyes!! Help!
