I currently have an intel integrated GPU Intel 5100 iris graphics and I would like to upgrade to the latest version of OpenGL available. I currently have OpenGL 3.0 and mesa 11.0.2 installed.
You dont have OpenGL 3.0... you have OpenGL 3.3 with some OpenGL 4.x extensions, because your card is OpenGL 4.x compliant.
I have Ubuntu 14.04.3 with Intel HD 4000 and Mesa 10.5.9 and i get:
glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.9 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 10.5.9 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions:
Obviously it is not possible that i have a higher OpenGL version with an older card..!
That OpenGL 3.0 you see is the compatibility profile! Your actual Core Profile is 3.3 and in a few months maybe 4.x
So then you would need ppa:oibaf/graphics-drivers for the absolute latest drivers, but it is not recommended unless the intel driver reaches OpenGL 4.x compliance!
I know this isn't a very comprehensive answer, but your OpenGL version is tied to your graphics card, in this case the Intel 5100 Iris integrated graphics. I would first check for updates with
sudo apt-get update && sudo apt-get upgrade and see if that does it. If not, it is possible that your card does not support anything above OpenGL 3.0, but you could look for a PPA to get a more up to date version of your driver. This can be dangerous though, so be warned.
