Ambient light & View selector

Out of nowhere the ambient light shuts it self off and I can get it to stay on. I change it in the settings in the Display Manager and it doesn't stick. It keeps reverting back to the light being greyed out, the setting turned off and set to zero.

Also, I have the view selector set to the space bar key stroke and that is no long working. I do a command search and SW says "View Selector" (which SW has an icon for) says was not found.

Looking for help.
