matlab 2015b does not work with flag nosoftwareopengl, Command line

Hi:

Matlab export, I installed matlab2015b, with command line, I run matlab with -nosoftwareopengl flag, but it seems it does not work, my matlab log file shows that it is still softwared, and it is quite long to render the result images...

My OS is ubuntu14.04 and here is my mablab log file:

If I run matlab from commandline , i also got this output;

                          Version: '3.0 Mesa 10.5.9'
                           Vendor: 'Intel Open Source Technology Center'
                         Renderer: 'Mesa DRI Intel(R) Sandybridge Mobile '
                   MaxTextureSize: 8192
                           Visual: 'Visual 0xab, (RGBA 32 bits (8 8 8 8), ...'
                         Software: 'true'
             HardwareSupportLevel: 'full'
        SupportsGraphicsSmoothing: 1
    SupportsDepthPeelTransparency: 1
       SupportsAlignVertexCenters: 1
                       Extensions: {196x1 cell}
               MaxFrameBufferSize: 8192

what does it mean Software: 'true' and HardwareSupportLevel: 'full'? I mean you can just have one way to do the render, right?

opengl('save', 'hardware')

then exit and re-enter MATLAB.
