Thanks for your replies. I finaly found the answer: These iMac G3 have a hardware brightness control. I had to open it and I found two "brighness" and "focus" (don't touch it!) controls, at the left bottom side of the screen. It was just hidden.
I'll post any other difficult problem later ;) Jean-Christophe -- To UNSUBSCRIBE, email to debian-powerpc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
