I always suspend my laptop in two different ways:

  • Clicking "suspend" on the right top corner.
  • Using the command line sudo pm-suspend.

Depending on how I do it, the bahaviour is different. The first way, it requires the password to wake up from suspend, but if I suspend from Terminal, it doesn't ask me for password while waking up from suspend. Is this one the "normal" behaviour? Can I get the laptop asking me the password, even if I suspend from Terminal?


If you suspend using sudo pm-suspend it will NOT block your session while you're using GUI, which is insecure. so you'll need to do it from panel or you can do it using

sudo pmi action suspend

For that you nee to install powermanagement-interface

sudo apt-get install powermanagement-interface

and suspend using

sudo pmi action suspend
  • Well, the issue is not about the panel but the terminal. I have by default that the shell doesn't ask me for password when using sudo. What I meant is that, when I suspend from command line and then resume the laptop, it doesn's ask for password (it asks for it if I suspend from panel). – Francisco Gallego Salido Sep 10 '15 at 7:11
  • Sorry for my English. I get this error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files – Francisco Gallego Salido Sep 10 '15 at 9:16
