<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>

<p>Hi Tom, <br>

<p>Thanks for your message. Here is the error message. I am
confused as well, because X2go should be running at 24 bit as
I read from the internet.</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>
