Edit /etc/acpi/actions/sleep.sh to add a single line like

echo "hello" > /tmp/acpi_test

then see if /tmp/acpi_test was created. This will show if sleep.sh is 
being called.

(I just spent the holidays getting a T42p to work with acpi, etc). Only 
thing that doesnt seem to work is DRI with x.org :/ Other than that the 
transition from my T30 seems to have worked quite well :-)

However, i doubt your troubles here are really with ibm-acpi, since from
my understanding this is only triggering the events. Since your acpid
recieves the event everything regarding this seems to be fine. Your
trouble is that the suspend doesn't work. In fact, i think your echo or
something else with the script doesn't work.

The acpid log states that the script exits with exit code 1, which means
an error. The only call in your script is the echo line. The return code
(exit code) of the echo command is independent from what happens after
the "mem" gets written into /sys/power/state. This means that either
echo is not able to write into /sys/power/state or the execution of the
whole sleep.sh script fails.

Please check if your /etc/acpi/actions/sleep.sh is set to executable.
And if so try launching it manually from a root console and see if you
get any output.

Andr&eacute;.

Just to make sure:

#ls -lah /etc/acpi/actions/sleep.sh
-rwxr-xr-x  1 root root 46 2005-01-04 00:56 /etc/acpi/actions/sleep.sh

#cat /sys/power/state
standby mem disk

#echo "mem" &gt; /sys/power/state
#cat /sys/power/state
standby mem disk

Is there some other kernel logging I could maybe turn on to see what is
going on?
