Firstly, UpsetChaps have thrown up their official Quake 4 guide, very reminiscent of their DOOM 3 guide, covering the HUD to help with your graphics card and its OpenGL 1.4+ display drivers, and etc.
And secondly, the GNU/Linux version client/server port of Quake 4 has been released! Don't forget to head on over there and check it out and the readme Linux users!
