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.
