Hello Linux Geeksters. In this article I will show you how to use the Steam Chat From Pidgin, on Ubuntu 13. Salamander, Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 15 Olivia, Linux Mint 14 Nadia and Linux Mint 13 Maya. 
As you know, Steam on Linux uses a lot of resources and so, using the Steam chat without having the Steam Client opened is an awesome thing for your laptop’s battery and cpu usage. The plugin needed for integrating Pidgin with the Steam chat is pidgin-opensteamworks.
The plugin is available in a PPA, so all you have to do is:
$ sudo add-apt-repository ppa:lasall/pidgin-opensteamworks
$ sudo apt-get update
$ sudo apt-get install pidgin-opensteamworks
