Comment 20 for bug 137247

So until it's fixed you can use pam-keyring-tool provided above by Troels Faber. Just put it in some folder (let's say /usr/local/bin), create small script (I created /usr/local/bin/un_lock ) with 2 simple lines:

#!/bin/sh
echo "YOUR_PASSWORD" | /usr/local/bin/pam-keyring-tool -u -s

Then do "sudo chmod +x /usr/local/bin/un_lock /usr/local/bin/pam-keyring-tool"

Finally under System-->Preferences-->Sessions create new session with command /usr/local/bin/un_lock .

This way it works perfectly for me.

BTW if you use suspend/hibernate and want you connection to be restored after it, create 2 scripts described in https://help.ubuntu.com/community/WifiDocs/NetworkManager in "Suspend support" section.

I hope this bug will be fixed ASAP because IMHO it's highest priority for standard home notebook users.
