    This suggest that your vendor's OpenGL driver may not be properly installed on your system.

    Run:

    xdpyinfo
    glxinfo

    and post the output in [code]...[/code] blocks.

    xdpyinfo, under "number of extensions:" should list "GLX" as a valid X extension, if your OpenGL drivers are properly installed. And "glxinfo" should show you useful information, via GLX, about your OpenGL implementation. For instance, here:

    Code :
    > glxinfo | egrep 'OpenGL (vendor|renderer|version|shading language)'
    OpenGL vendor string: NVIDIA Corporation
    OpenGL renderer string: GeForce GTX 560 Ti/PCIe/SSE2
    OpenGL version string: 4.4.0 NVIDIA 331.20
    OpenGL shading language version string: 4.40 NVIDIA via Cg compiler

    Yep, certainly indicates that you don't have OpenGL drivers properly installed on your Lenovo IdeaPad Y580.
