Public bug reported: On my Leveno Y580, when the display manager starts, the screen brightness is set to the lowest possible level. On this laptop, it means the backlight is totally off, so you get nothing on screen at all.
Turning up the brightness with hotkeys works, but this has to be done on every boot, and it appears to the user that the display is not working at all.
