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.
