Please describe the problem:
If two users are logged in (on a laptop), then the idle timeout from the non-active user will affect the power use of the active user.

The way this manifests itself is that the screen brightness dims while the machine is in use.

Changing the brightness back and continuing to work will keep the brightness at the expected level.

Steps to reproduce:
