IBM T60 issues with resume from zzz

[Arvid Warnecke]

Hello everybody,

I am new to the list as the T60 is my first PC laptop and furthermore
the first mobile computer I run FreeBSD on. When I have been using
FreeBSD on my workstation I did not care too much about any
powermanagement and stuff like that.

I did some research and found old messages about using acpi_ibm and
devd. So I edited my loader.conf to load acpi_ibm and /etc/rc.conf have
these two more lines now:

dev.acpi_ibm.0.events=1
hw.acpi.lid_switch_state=S3

I then added this to my /etc/devd.conf

# ACPI_IBM
notify 10 {
	   match "system" "ACPI";
	   match "subsystem" "IBM";
	   match "notify" "0x04";
	   action "/usr/sbin/zzz";
	  };

Now the T60 goes to sleep complimentary but does not wake up at all. I
read a few times about issues with Xorg running, but this does not seem
to make any difference...

Where can I get more information about fixing the resume/ wake up? Has
somebody already got the resume working on his/her IBM T60 notebook?

Thank you very much in advance.

Best regards,
Arvid
