Bug report

Steps to reproduce

I find it difficult to produce the steps for reproduction

What is expected?

I expect the backlight to work all the time while hyperion is running.

What is actually happening?

After a while, the backlight stops working, and restarting hyperion helps.

I have allocated time to study the problem, the backlight is turned off after the screen is locked. There was no such thing on previous versions of hyperion.
