I got a lead by running: $ LIBGL_DEBUG=verbose glinfo|more libGL: OpenDriver: trying /usr/local/lib/dri/i965_dri.so [intel_init_bufmgr: 1317] Kernel 3.6 required. libGL error: failed to create dri screen libGL error: failed to load driver: i965 Looking into that function (intel_init_bufmgr() in port graphics/libdrm, mesa-17.1.1/src/mesa/drivers/dri/i965/intel_screen.c) reveals that it tries this: if (!intel_get_boolean(screen, I915_PARAM_HAS_WAIT_TIMEOUT)) { fprintf(stderr, "[%s: %u] Kernel 3.6 required.\n", __func__, __LINE__); return false; } But, I915_PARAM_HAS_WAIT_TIMEOUT does not exist on 10.x! It is missing in src/sys/dev/drm2/i915/i915_drm.h, so it fails, and resorts to sw rendering. Bengt
