Running a command on wake-up from suspend

[allanlewis]

I am running MythTV and have found that mythtv-backend prevents the computer from suspending. So, I wrote a simple script:

#!/bin/sh
gksudo stop mythtv-backend
gksudo pm-suspend

This works perfectly and the computer resumes correctly (most of the time). However, I now need to restart the MythTV backend, which I currently do manually, via a desktop launcher that runs:

gksudo restart mythtv-backend

I would like to be able to have this command (and maybe others) run when the machine resumes from suspend. I have read elsewhere about /etc/pm/sleep.d but I'm not sure how to put a "root" command in there, such as restarting a service...

Well, scripts in /etc/pm/*.d/ should be run with root privileges, so just omit the gksudos.

#!/bin/sh

# Arguments can be:
#    "suspend suspend"
#    "resume suspend"
#    "thaw hibernate"

case "$1" in
        "suspend"
                stop mythtv-backend
                ;;
        "resume"
                start mythtv-backend
esac

And save it as /etc/pm/sleep.d/90_mythtv-backend-fix or something.

Thanks!

Thanks, I wanted to do something else on resume and wondered where the script should go..

Hey, I don't really understand this stuff, but I'd like to run a command every time the computer wakes from sleep or hibernate. Should I modify #2 in this thread and save it as "/etc/pm/sleep.d/90_psmouse" ?

It would be great if I understood what was happening here too.
Thanks for any answers to this question.

#!/bin/sh

# Arguments can be:
#    "suspend suspend"
#    "resume suspend"
#    "thaw hibernate"

case "$1" in
        "suspend"
                sudo modprobe -r psmouse; sleep 2; sudo modprobe psmouse

                ;;
        "resume"
                sudo modprobe -r psmouse; sleep 2; sudo modprobe psmouse

esac
