Laptop-Mode doesnt resume after suspend...

alexertech · 2008-05-22 23:47:39

Hi everybody.

Just that. After a suspend, laptop-mode doesn't wake up, and the famous "thick noise" appears again...

I don't see where can i set the modules that should be reloaded after a suspend/hibernate state. Only found which modules should be unloaded after.

Thanks in advance!

Try unplugging and then reconnecting the AC to your laptop. That usually fixes it for people using laptop mode.

A bit tedious, though.

There's surely a more elegant solution than this

For example, if you're using pm-utils to suspend/hibernate you can create a file called /etc/pm/sleep.d/10lmrestart (the actual filename doesn't matter, as long as the file is in this directory) that looks something like this:

#!/bin/bash
case $1 in
    hibernate)
        /etc/rc.d/laptop-mode stop
        ;;
    suspend)
        /etc/rc.d/laptop-mode stop
        ;;
    thaw)
        /etc/rc.d/laptop-mode start
        ;;
    resume)
        /etc/rc.d/laptop-mode start
        ;;
    *)
        echo Something is not right.
        ;;
esac

You get the idea... Alternatively you can use hibernate-script (package in extra) to better configure what happens when you suspend/resume... Or you can write your own script that stops laptop mode before sending the laptop to sleep and then starts it again when after resume...

EDIT: BTW, the script above must be made executable with chmod +x in order to work.

Hey fwojciec!

I totally forgot to told you: THANKSSSSSSSS!!!

This works perfect.

Again: THANKS!!

That is a cool solution, fwojciec. Perhaps this would be the wrong forum to ask, but I would like to do the same in Ubuntu -- does anyone here know what kind of script I should write, and where I should put it?

OK, I found the solution myself. For future reference I will put it here. Ubuntu uses pm-utils for power management too. Thus the only necessary modification to fwojciec's script is to change the rc.d folder to init.d. For example:

hibernate)
        /etc/init.d/laptop-mode stop
        ;;
