    <p>So it looks like the relevant error is:</p>
    <p>
      <blockquote type="cite"><span style="font-size: 10pt;"><font
            face="monospace">Cannot load library
/usr/libexec/UCSF-ChimeraX/lib/python3.9/site-packages/PyQt5/Qt/plugins/platforms/libqxcb.so:
            (libxcb-icccm.so.4: cannot open shared object file: No such
            file or directory</font>)</span></blockquote>
      But the ldd output is even more helpful because there are other
      missing libraries.  The missing packages are xcb-util-wm,
      xcb-util-image, xcb-util-renderutil for libxcb-icccm.so.4,
      libxcb-image.so.0, and libxcb-render-util.so.0 respectively.  So
      you should "<font face="monospace">sudo yum install xcb-util-wm
        xcb-util-image xcb-util-renderutil</font>" to fix this
      particular problem.<br>
    </p>
    <p><br>
    </p>
    <p>Since you don't have those libraries already installed, it seems
      like you have installed Chimerax on a remote server instead of a
      desktop system.  That is officially not supported unless you are
      running ChimeraX in nogui mode (which doesn't need those
      libraries).   That said, using VirtualGL on the server can work
      around remote display problems.</p>
