      as (and I quote) "* gallium llvmpipe as the default software renderer rather than classic swrast"... it seas it dose ??
      I'm curious about this too. I wanted to run some tests to see if one performed with opengl better.

        You could "trick" glxinfo into spitting out some details while avoiding long lists of extensions and visuals:

        Code:
        steve@x1:~$ [B]glxinfo |grep ': '[/B]
        name of display: :0
        display: :0  screen: 0
        direct rendering: Yes
        server glx vendor string: SGI
        server glx version string: 1.4
        client glx vendor string: Mesa Project and SGI
        client glx version string: 1.4
        GLX version: 1.4
        OpenGL vendor string: Intel Open Source Technology Center
        OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile 
        OpenGL version string: 3.0 Mesa 8.1-devel
        OpenGL shading language version string: 1.30
        
        steve@x1:~$ [B]LIBGL_ALWAYS_SOFTWARE=1 glxinfo |grep ': '[/B]
        name of display: :0
        display: :0  screen: 0
        direct rendering: Yes
        server glx vendor string: SGI
        server glx version string: 1.4
        client glx vendor string: Mesa Project and SGI
        client glx version string: 1.4
        GLX version: 1.4
        OpenGL vendor string: VMware, Inc.
        OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
        OpenGL version string: 2.1 Mesa 8.1-devel
        OpenGL shading language version string: 1.20
        If you configure that environment variable at boot, I'd imagine that all OpenGL would use LLVM.

          and how would one go about that ?
          currently I put a shell script in start up and that dose not seem to do it ...or adding it to the grub boot line

              Latest update - kernel 3.5.0-10 - breaks nfs. booting back to -9 solved it for now.

              UPDATE: It appears the problem I was having was my server is using NFSv3 and the latest update moved fstab mounting to NFSv4 or somehow changed the setup of NFS. Adding "vers=3" to fstab fixed it.
