Hello! Pbbuttonsd work alright (volume, and cdrom eject buttons work) for me except one feature: I can't change brightness. When I run gtkpbbuttons it shows me that brightness level is 15 in case I push brightness up button and in case when I push brightness down button. I'm running standard kernel-image-2.6.6-powerpc kernel. Is it problem with nvidia card inside my powerbook? (PowerBook6,2 = G4 12" 1Ghz with nVidia Go) Peter.
