    <p>Tat,</p>
    <p><br>
    </p>
    <p>To use ChimeraX with x2go, you need to install virtualgl and then
      use "vglrun chimerax" to run ChimeraX.  The problem is probably
      not the 24-bit visual, but the OpenGL support.</p>

      <div>Hi Tat,
        <div class=""><br class="">
        </div>
        <div class="">  Chimera has no controls for color depth.  I
          guess its OpenGL rendering asks for 8-bit color depth for the
          OpenGL context.  What error does Chimera give?  Using less
          than 8-bit color depth for visualization is absurd.  X2Go must
          be able to do 24.</div>
