Utah GLX was a project aimed at creating a fully free and open-source basic hardware-accelerated 3D renderer using the OpenGL rendering API on Linux kernel-based operating systems. Utah GLX predates Direct Rendering Infrastructure, which is what is used as of 2014. John D. Carmack worked on Utah GLX.
