I just start OpenGL programming , would you advise me about which book are the best book in OpenGL programming in X-Window ? Thank you.

Probably the Red Book (OpenGL Programming Guide). It''s API independent (because of GLUT). If you really want something specific to X, I''d addume Mark Kilgard''s OpenGL Programming for the X Window System is good, given the author''s other work in the area, but I haven''t read it myself.

Both books are in our Books section.
