Thinkpad Display Problem

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!
