I have this issue when on advanced optimus integrated the lowest brightness completely turns off the screen. When under 10 percent images seem to be crushed by black spots.

This doesn't happen when on dedicated graphics only mode, as lowest brightness still shows a dim image of the screen. Only on advanced optimus the screen completely turns off at lowest brightness.

I've tried to apply the hot panel fix on dedicated gpu mode only and have no confirmation on whether it has been applied or not as I can continue to install it with subsequent opening of the program.

It's quite frustrating because the lowest brightness or anything below 10 percent is basically unusable on integrated. Is anyone else having this issue?
