OpenGL core profile context flags: (none) OpenGL core profile shading language version string: 1.40 OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.0-devel (git-7f57408 saucy-oibaf-ppa+curaga) OpenGL renderer string: Gallium 0.4 on AMD CAYMAN However, glxinfo, while it now reports that Mesa 10.1 is in use, still reports only OpenGL 3.0 (compat profile) and OpenGL 3.1 (core profile): $ glxinfo | grep OpenGL $ sudo add-apt-repository ppa:oibaf/graphics-driversģ.) Dist-upgrade (rebuilds many packages) I used the exact same steps as explained there: 1.) Add the PPA Repository StackOverflow: OpenGL & GLSL 3.3 on an HD Graphics 4000 under Ubuntu 12.04 It is however possible to install Mesa 10.1 (implementing OpenGL 3.3) from this PPA as explained in this thread: Ubuntu 13.10 only provides Mesa 9.2 (implementing OpenGL 3.1) "out of the box".
I want to use the open source drivers ( radeon), which rely on Mesa for their OpenGL implementation. I am trying to get an OpenGL-based rendering engine that relies on OpenGL 3.3 and GLSL 3.3 to run on Ubuntu 13.10 using an AMD Radeon 6950.
