Thanks and  I wish you could help answer this question.Now I know Mesa provides DRI and GLX, when I installed xorg-server,there're also libraries named like libdri.so and libglx.so in /etc/X11/....(somewhere).What I don't understand is, why Xorg-server still provides its own DRI and GLX while Mesahas done this already?
