Many a day on the Ubuntu Forums, I stumble upon posts like: “Program X doesn’t work under ubuntu, I’m leaving”. As it turns out, some of these posts are for the Source games, mainly the multiplayer ones (Counter Strike: Source, Day of Defeat: Source, Half Life 2: Deathmatch, Team Fortress 2). For that purpose I’m gonna make a short guide, just to show how I had luck getting the Source games to work.
