Ubuntu won't suspend anymore, but it did upon install

  • 772

I fresh installed Ubuntu 10.10 back when it came out, and my laptop was suspending fine. All of a sudden, I can't get my laptop to suspend anymore. It's an HP Pavilion dv2-1110, but I don't think it's a hardware issue, here's why:

  • It suspended fine upon first install. I haven't installed any new kernels since then, but I have installed tons of packages, so it's probably a package.
  • The suspend and hibernate options disappeared from the shutdown menu. If I press my keyboard's suspend button (or if I close the lid) I get the following message: alt text
  • If I try the command pmi action suspend, I get the error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files.
  • If I try the command echo -n mem > sudo /sys/power/state I get absolutely no output and no visible effect.

What might be causing this behavior? I thought a list of installed packages might be useful, but it's huge and I don't know how to post it here in collapse/expand mode or something.

EDIT:Just in case someone asks, none of the installed packages are kdm or anything like that (which would justify the lack of options in gnome's shutdown menu).

    Open the Software center and type 'acpi-support' in the search bar. Make sure, that the package is installed. Reboot, and voilà: suspend and hibernate are back and working again for me. Maybe this will fix it for you, too.

  3. I know this is a bit late, but I am having the same problem as you.

    It turns out laptop-mode-tools automatically removes pm-utils upon installation. I'm not sure why, but it would seem the 2 do not like coexisting.

    Try installing pm-utils again with: sudo apt-get install pm-utils

    For reference, I found this out from: http://ubuntuforums.org/showthread.php?t=1660478

    I hope this helps to solve your problem.
