Hi, I apologize in advance for the simplistic question. I've searched every avenue I can find and haven't been able to resolver this issue. I recently attempted to upgrade my installed instance of Mesa & OpenGL as my chipset is completely capable of running GLSL and GL versions 3 and above. I followed the steps in <a href="http://feedesktop.x.org">feedesktop.x.org</a>'s Modular Developers guide. the <a href="http://wiki.x.org/wiki/ModularDevelopersGuide">http://wiki.x.org/wiki/ModularDevelopersGuide</a> Once finished, I was surprised to see my OpenGL version and GLSL versions still at 1.2 and 2.1 respectively. The graphical data for my system is: 2.0 VGA compatible controller: Intel Corporation Sandy Bridge Integrated Graphics Controller (rev 09) model name : Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz cpu MHz : 2301.000 model name : Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz cpu MHz : 2300.000 X.Org version: 1.13.99 dimensions: 1600x900 pixels (423x238 millimeters) depth of root window: 24 planes direct rendering: Yes server glx vendor string: SGI server glx version string: 1.4 -- OpenGL vendor string: Mesa Project OpenGL renderer string: Software Rasterizer OpenGL version string: 2.1 Mesa 9.1-devel (git-037b4f8) OpenGL shading language version string: 1.20 Linux 3.2.0-0.bpo.3-amd64 The GPU referenced from lslci above is: Sandybridge Intel® HD Graphics 2000/3000 (used in 2nd Generation Intel® Core™ i7/i5/i3 processor family) Which I understand to be driven by an i915 intel graphics driver. Please let me know if you need any other data or information.
