[gentoo-user] suspend/resume

[Grant]

Is there a way to shut the power of my laptop down and then power it
back on and have it resume right where it was when it was powered
down?  I think this is called suspend/resume.  I see there is a kernel
called suspend2-sources.  Is there any way to do it with my
hardened-sources kernel?

This uses suspend2, which is an externally maintained patch to the
kernel [1].  Suspend2 may work better than the in-kernel suspend
implementation for some cases.

I know nothing about the hardened kernel, but you should be able to
enable the 'normal' suspend to disk and suspend to ram options.  Look
under "Power management options..." and turn on "Software Suspend" for
suspend-to-disk support.  You can also add "ACPI...->Sleep States" for
suspend-to-ram.

I highly recommend merging and using hibernate-script.  This is an
advanced script that can handle most suspend/standby tasks.  Just edit
the config file[s] in /etc/hibernate/, and run "hibernate -F
<path_to_config>".

I also recommend getting the ~arch version of hibernate-script, so
that you can start off using the new config file layout.

Thanks a lot.  I'm going to check this out.

I use suspend2-sources, and it works very well!

Sure. Install the hibernate package and configure /etc/acpi/default.sh
properly:

                 case "$action" in
                         power)  #/sbin/init 0
                                 logger "$group, ACPI action $action thru default.sh invoked - calling /usr/sbin/hibernate"
                                 /usr/sbin/hibernate
                                 logger "/usr/sbin/hibernate finished"
                                 ;;

You'll also need to compile the "button" module in the kernel.

Dunno. But you don't *HAVE* to use suspend2 to do suspend-to-disk. The
plain kernel does this as well.

The primary difference between suspend in the vanilla (and hardened)
kernel and suspend in Suspend2 is that Suspend2 is much faster.  I
don't have any hard numbers, but I think the difference is something
like twenty seconds versus a minute to fully suspend on my laptop.
This isn't normally a big deal, and you don't need to migrate from the
hardened kernel.

Do you think it would suspend Windows XP running in VMware Workstation properly?
