Public bug reported:
Since upgrading to 14.10 every time I open the laptop lid the system
hangs after enabling the keyboard but before turning on the display.
That is the backlight on the LED screen is not turned on. This issue
has occurred occasionally since 12.4, but is now completely consistent.
