Title: Backlight stays on with black screen when monitor should be sleeping Status in mutter package in Ubuntu: Confirmed Bug description: My Screen Blank setting is set to 15 minutes. My Lock Screen settings are also set to automatically lock the system after the blank screen timeout is reached. After 15 minutes Ubuntu does lock me out, but the monitor does not power off as it's supposed to - the screen is simply black. Please see the attached video.
