[Bug 869050] [NEW] no brightness after idle and have to press a Fn+Brightness+/- to get the screen light up again

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

With no AC-adapter connected, I let my computer go into idle and turn of
the screen aafter a few minutes. When I then go back to work the screen
turns on, but the light is completely off. I then need to press one of
the brightness buttons to get it to light up again.

After the idle and the screen turns on, I can actually see the desktop,
but as I was saying, no light.
