The network manager applet, in Ubuntu Gutsy, provides a save feature that will automatically unlock your wireless keyring without the need for a manually typed password. This is a much welcomed feature, whereas in the past to unlock the wireless keyring required manual input.
When you enter a router WEP, or PSK, you can create a keyring password, so that your router password is automatically store and retreived when necessary. The only drawback is that you will have to enter your keyring password each time you login. To automatically use your GDM login password as your keyring password you can do the following:
sudo apt-get install libpam-keyring
Then edit your GDM configuration file:
sudo gedit /etc/pam.d/gdm
Your going to want to add at the bottom of the file:
@include common-pamkeyring
Then delete your existing keyrings. The next time you login, you are going to have to re-enter your rother WPA/PSK password, and when you set the keyring password, just use the same password that you use to login to your GDM account. Now when you login via the GDM you will automatically unlock your keyring and connect to the wireless network.
Note that if your have set up automatic GDM login, you may have to disable it, setup the wireless, then re-enable it. Otherwise cheers to automatic login
