    I don't use IDL, I am asking this on behalf of a user. We have two machines, his code ran on one, but not the other. I updated the machine where the code would not run to the newest version of IDL, same error:

    libGL error: No matching fbConfigs or visuals found
    libGL error: failed to load driver: swrast



    It appears that both machines have the same libraries installed. Although some of our machines have Nvidia, these two don't. We are also getting a 2nd error:


    !CGPLOTS -> attenp to call undefined function: DECOMPOSEDCOLOR



    Any ideas? Thanks

    Greg

    This is often a graphics driver problem. In the IDL Prerferences under IDL->Graphics, try setting the rendering to 'Software' and see if it helps.

    CGPLOTS and DECOMPOSEDCOLOR look to be from an external library. The paths to these routines will need to be added or repaired.
