I would like to have all my chat accounts logged in from one place. If you are like me and would like to have Facebook chat support to Pidgin on Mandriva 2009.1, here are the steps.
1. Download the facebook chat plugin for Mandriva from here. Select the correct platform.
2. Install the plugin (normally by double clicking on it and choosing Install in the box that pops up). Enter root password if prompted
3. Start Pidgin
4. Go to Accounts > Manage Accounts > Add
5. A new Facebook entry would be available under the Protocol list.
