I do not want to write a dri.so which will work either with DRI or with AIGLX.Let's put my questions one by one below.. 1>If some one( a vendor) gives me only the OpenGL driver(no DRI/DRM functionality) implementation, can i use that and build my DRI/DRM modules i.e. Can i write my own dri.so & drm.so and still use the vendor provided OpenGL? Excuse me as some of my questions can be abstarct or some cases invalid,too as i am new to this area :-( 2>In case of AIGLX, where can i find the code inside xserver where it redirects the libGL calls to the GL_dri.so 3>Can i get a comparison like pros & cons for both the architecture in different context/use cases?

No really, AIGLX is part of the DRI architecture. You have direct rendering and indirect rendering, in the direct rendering case libGL calls directly into GL _dri.so driver, which then calls into the kernel, in the indirect rendering case libGL calls get send to GLX in the X server, which sends them to the _dri.so driver which then calls into kernel. You can't really write an _dri.so that only works in AIGLX or DRI, well you could but it would be pointless.
