Sorry for taking so long to reply.
What is needed is a way for the server's GLX code to determine what
features are supported by the 3D driver that is loaded in the server.
If the driver doesn't support the required feature set, we have to
expose GLX 1.2. If it does support the required feature set, we can
expose GLX 1.4. There is code to do this on the client side, but it's
not clear to me how to adapt it to the server.
It's a project that has been on my to-do list for some months, but it
keeps getting bumped by other things.
