Best, Michael 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). Yeah, I was wrong :) libglx and libdri are part of xorg-server. Best, Michael

Yeah, I was wrong :) libglx and libdri are part of xorg-server. libglx can also be provided by driver packages. You can select the xorg one or others via eselect; proxy adam # eselect opengl list Available OpenGL implementations: [1] ati * [2] xorg-x11 Also, I imagine those kernel options supply an interface for the DRM/DRI driver.
