[Bug 49521] Re: Screen locks up black on laptop lid close.

 

OK, still broken.

Now - this is not an exact duplicate of the bugs listed in this thread -
The other Lenovo listed on here apparently will still allow ctrl-alt-del
to work, but on mine it does not.

I had intended on uninstalling 14.04, but this is a work machine and
unfortunately I have to keep ubuntu on it.  So now my problem - at
least, the most problematic problem - is that closing the screen renders
the machine unusable without doing a hard reboot.  And even then, it is
a crap shoot on whether or not it will reboot without cycling the power
a few times after that; it is also now rebooting to a flashing cursor
and just halting with absolutely nothing ever showing in any of the
logs... but only after it locks up because someone was unlucky enough to
close the lid.  If I am able to use the normal shut down or restart
method, then it is still suddenly making me log in twice when it does
reboot... once at a CLI, and then a second time at the regular GUI login
screen.

All of this, the freezing, the failed boot, the multiple logins - this
all started a few days ago.

So... do I file a new bug report, or keep adding to this one, or is this
just another "that's just the way it is" bugs that will eventually have
a workaround in a random thread somewhere?

Title:
  Screen locks up black on laptop lid close.

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: acpi

  On my Dell 640C laptop, my screen locks up black whenever I close the
  lid.

  Doesn't matter if I have it set to sleep/suspend, blank screen, or
  just no event. Whenever I close the lid, it locks up black and nothing
  short of restarting Gnome or rebooting can get my screen back.

  Thanks for any fixes/suggestions.
