Is a special flag expected? As Jerome mentioned, you could build mesa from our tree (rather than Fedora's tree). One other option *might* be to download a build of i965_dri.so from another distro's build of mesa, and then set the LIBGL_DRIVERS_DIR environment variable to the directory where you downloaded the library. -Jordan On Mon, Mar 25, 2013 at 5:59 PM, Jordan Justen jljus...@gmail.com wrote: On Mon, Mar 25, 2013 at 9:41 AM, violin yanev violin.ya...@gmail.com wrote: Hello, I was eager to try the OpenGL ES 3.0 support on the newest Mesa 9.1.
