Hello Everybody

First i'm not verry good in englisch but i will give my best in explaining my problem.


I own a Thinkpad T60p and installed the Kalyway Leopard 10.5.1 OS.
After Installation i updatet it to 10.5.2 with the Kalyway integratet Update.

My ATI FireGL will be fully recognized by OSX. FULL QE/CI!

But The Problem is: When i plug the AC Cable Out: OSX reduces automically the Brightness of the Display to a lower Level. The Left Area of the Display gets Black and the Right Area gets a normally lower Brightness.

On Windows XP or in the BISO i have no such Brightness problems!

I have tried various PowerManagement.bundles but the Problem is still here.

Another mystery ist that i cant set with the "pmset" command the attribute "lessbright" to zero.

I hope someone has a Solution for this Problem or a Idea to find her.

Nice Evening!

i have the same problem on 10.5.4 - did you ever find a solution?

me too，any one can help us to adjust the brightness??

I have a X60s and a T60 and no such problems whit a default Kal 10.5.2 install. I used speedstep kernel and Powersaving bundle. Runs fine (only USB and wifi doesn't work right)
