    <p>Works for me :-)</p>
    <p>I just tried the headless version of Chimera on CentOS 7.5.   I
      didn't use a script, but did the following commands:</p>
        open 6c7m<br>
        windowsize 512 512<br>
        surf<br>
        copy file test.png<br>
        stop<br>
    <br>
    And it created the image file and exited without a problem.<br>
    <br>
    So it is unclear what the problem is.  You'll need to run gdb to
    find out where the segmentation fault occured.  Create a debugging
    version of the chimera program script, and change the 'exec $python'
    at the end to 'gdb $python', run it, and then in gdb, 'run
    $CHIMERA/share/__main__.py chimera_surface.py'.  When chimera
    segmentation faults, type 'bt' to get a backtrace and send it to me.<br>
    <p>FYI, the headless version of Chimera comes with libOSMesa, so you
      don't need to install it.  But it shouldn't cause problems if you
      did.  The libOSMesa distributed with chimera is ancient, version
      7.6.1. So, if the backtrace shows that the bug is in libOSMesa,
      there's a good chance that if you replace chimera's libOSMesa.so
      with the system version, it will work.</p>
    <p>    Good luck,</p>
