Bug description:
[ Impact ]
On some machines when the screen blanks, the LCD backlight stays on.
[ Workarounds (reported to work by some people) ]
* Configure the monitor (in its own menus) to not auto-switch inputs.
* Change from HDMI to DisplayPort cables.
* Disable HDMI audio output.
[ Test Plan ]
0. Make sure you're using an LCD (not OLED) so you can see if the backlight
is on.
1. In Settings -> Power -> Screen Blank, set the inactivity period to 1
minute.
2. Verify after 1 minute that the screen is blank and the backlight is also
visibly off.
