Public bug reported:
Oneiric originally worked fine, but after a recent update (sadly not
sure exactly what package versions, but one or two weeks ago) this
started happening:
The system boots fine and everything works, but once I close and re-open
the laptop lid, the screen is black (no backlight) and won't wake back
up (no matter how many times I close and re-open the lid). This is on
AC power. In my power management settings, I have "When the lid is
closed" set to "Do nothing" (i.e. just blank the screen) for both AC
power and battery.
The system is still running (I think) but the display stays black. The
only way (that I have found) to recover is to reboot.
If I switch to a text console before closing the lid, it blanks and
unblanks fine. Trying to switch to text console _after_ the screen has
gone into permablack has no effect.
