[gentoo-user] Modifying Suspend Script?

[gentoo-user] Modifying Suspend Script?

Hi, I always need to reconnect my laptop pcmcia wireless card to my WAP
when awaking from suspend. It would be nice if I could add two commands,
ifconfig and dhpcd, to the script which controls awaking from suspend.
Anyone know which file I can edit?

I don't exactly remember, but I think Hibernate-script allows to do this.
There are configuration files which state commands to be executed during
various events.

You can also tweak acpid script. Ask acpid to listen on power button event
and setup a script which calls your routine and then pm-suspend

Assuming you're using pm-utils [1], inside /etc/pm/suspend add a script with:

#!/bin/bash
case $1 in
   thaw|resume)
      ifconfig <args>
      dhcp <args>
esac

and it should do the trick.

This worked like a charm. Except the dir was sleep.d, not suspend. Thanks!

Something similar happens with my bluetooth dongle; I need to stop the
service, unload the kernel module, load it again, and start the
service once more.

Others have already gave you answers. I do not believe you use
systemd; but for whomever else that does, I leave this here: systemd
has a set of directories (one for sleep, another for hibernate, and a
third one for "hybrid" modes), where you can drop any executable you
want to be executed in any of those situations. From [1]:

"""
Immediately before entering system suspend and/or hibernation
systemd-suspend.service (and the other mentioned units, respectively)
will run all executables in /usr/lib/systemd/system-sleep/ and pass
two arguments to them. The first argument will be "pre", the second
either "suspend", "hibernate", or "hybrid-sleep" depending on the
chosen action. Immediately after leaving system suspend and/or
hibernation the same executables are run, but the first argument is
now "post". All executables in this directory are executed in
parallel, and execution of the action is not continued until all
executables have finished.
"""

My bluetooth problem gets fixed with a little executable script in
/usr/lib/systemd/system-sleep:

#!/bin/bash

case "$1" in
    "post")
        sleep 3
        systemctl stop bluetooth.service
        rmmod rfcomm
        rmmod bnep
        rmmod btusb
        rmmod bluetooth
        modprobe bluetooth
        modprobe btusb
        modprobe bnep
        modprobe rfcomm
        systemctl start bluetooth.service
        ;;
esac

exit 0
