Re: how to run script after suspend to disk

[Paul Johnson]

I use the acpi support under /etc/acpi/events and /etc/acpi/actions
for sleep.  The event represents a lid closure or FN-Suspend and
points at an action file. The script in the action directory tells the
system what to do.

The sleep.sh file I now use is here.If you want something to happen
after awaking from suspend mode, it should be easy to see where to put
it in.

I do not have any luck with the "hibernate" rpm or the
"gnome-power-manager" rpms, but the basic acpi method does work here.

------------------/etc/acpi/events/sleep----------------------------

# /etc/acpid/events/sleep

event=button[/]sleep
action=/etc/acpi/actions/sleep.sh %e

-----------------------------------------------------------------------------------------



------------------/etc/acpi/actions/sleep.sh
#!/bin/sh
#
# ACPI suspend to ram script

#Modules to unload before suspend. This are known troublemakers!
MODULES="tg3 uhci_hcd ehci_hcd hci_usb ipw2200"

###if you use linuxant modem drivers you also need this
##MODULES="$MODULES hsfusbcd2 hsfmc97ali hsfmc97via hsfmc97ich
hsfpcibasic2 hsfserial hsfengine hsfosspec hsfsoar"
