screen goes blank instead sleep

[Imobach González Sosa <imobachgs@gmail.com>]

Hi all,

I'm trying to set up "suspend to ram" (sleep) on an iBook G4 but I
have some questions. I've searched the archives and I found no
answers, but sorry if I'm wrong about this.

Ok, I'm trying a vanilla 2.6.11.10 kernel. When I push the "power"
button my screen goes blank, but machines doesn't go to sleep. I've
also tried with unstable 2.6.11 kernel sources.

I checked the pbbuttonsd configuration and it seem to be right. So I
checked my kernel config and I don't see anything about suspend to
ram. I've tried to load an Ubuntu's kernel config file (when
configuring the kernel options) and it complains about
CONFIG_SOFTWARE_SUSPEND (I don't know if it makes sense).

Am I missing something? (sure)
Any idea?

Thank you in advance.
