Running OS 10.2.8 on G4/p33 quicksilver and realized I can no longer bring up the brightness/contrast adjustment in the Displays pane. Pressing the light on the bottom left front of the display does not bring up the Displays pane. Even when I boot into classic, I no longer have this option. I have found mention on Apple's site, but no effective fix. Would upgrading to 10.3.5 solve this issue? Any other fixes? thanks.
