[[/Discussion|Discussion]]|| ---- ||{{http://www.mesa3d.org/gears.png}}||'''Mesa''' is an open source 3D computer graphics library that provides a generic OpenGL implementation for rendering three-dimensional graphics on multiple platforms.|| <> == Get informations from Mesa == First, you will need the Mesa utilities: {{{ # apt-get install mesa-utils }}} Among the mesa tools, glxinfo will help you to know more about the chip that your computer uses. The command {{{ $ glxinfo | grep OpenGL }}} will report something similar to this: {{{ OpenGL vendor string: Intel Open Source Technology Center # The manufacturer OpenGL renderer string: Mesa DRI Intel(R) Haswell Desktop # The type of the chip OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2 # The OpenGL version fully supported, here 3.3 thanks to Mesa 10.3.2 . OpenGL core profile shading language version string: 3.30 # The GLSL version fully supported }}} If in the {{{OpenGL renderer string:}}} you see {{{llvmpipe}}}, that means your system doesn't use the GPU but the CPU instead to render the computer graphics. If you want to use the GPU look at the [[GraphicsCard]] page. Many times you just need to install the DebianPkg:firmware-linux-nonfree package from the {{{non-free}}} repositories, in order to active the driver. === 3D acceleration === To determine whether 3D acceleration is working, use the glxinfo tool. Run the following command: {{{ $ glxinfo | grep rendering }}} The output should be: {{{ direct rendering: Yes }}} == Testing performance == To see how many frames per second your video card is putting out, run the following command: {{{ $ glxgears -info }}} Note: The gears test is not very effective, many drivers work very well with a bad FPS in this test. == External links == *[[http://www.mesa3d.org/|Mesa homepage]]
