I have a Al 1,25 PB and 10.4.2 seems to have disabled my keyboard backlight. Is this an issue in this upgrade? What can I do to get it back? I have all preferences set properly, Automatic Brightness in Displays and Illuminate Back Light in Low Light Conditions. Note: I set preference and noticed the Illuminate in Low Light was de-selected. I selected and restarted to see if I had recovered functionality. While writing this post I I checked the preferences for reference and noticed Illuminate in Low Light de-selected again. Sensors work because when I cover the speakers the screen dims. I will post here restart and post back.

Preferences remained but still no available Backlight.

Issue resolved by hitting operator upside head with 2x4. F10 increases backlight brightness.
Under Keyboard and mouse I had selected key functionality button thinking the opposite of what the selection intends, disabling the F1 - F12 keys.
