I'm writing to you with feedback since I remembered you wanted
to let know if any of the methods worked. I got to it a bit
later than expected (sorry for the delay) and let me tell you it
was painful indeed. However the final solution was with
VirtualGL with Cygwin combination - Installed Cygwin with all
tools needef for X11 forwarding, server... including the
VirtualGL client. On server installed VirtualGL server. Then
using XLaunch (cygwin provides) and setting the right $DISPLAY
variable it is possible to run and quite smoothly operate with
visualisation programs (vglconnect, vglrun). Chimera, ChimeraX
and also PyMOL works just fine.<br>
<br>
Thank you for the previous help and advice, it pointed me in
this direction! Have a great day.<br>
<br>
Kind regards<br>

<p>Yes, as you discovered, remotely displaying 3D graphics is
problematic. Sometimes it works, usually if the graphics
driver on the remote computer and the local computer are the
same (same manufacturer, same operating system, i.e., same
variant of Linux and version).</p>
<p><br>
</p>
<p>In your case, I'd recommend installing the VirtualGL package
on the CentOS 7 computer, along with a graphics card and its
driver. That way the 3D graphics are done on the CentOS 7
computer and an image is sent to your computer. VirtualGL is
available from the epel repository and virtualgl.org. This is
also the solution for nomachine and x2go.<br>
</p>
<p><br>
</p>
<p>An alternative would be to try the free cygwin.org X11
server, or a commercial X11 server, like Exceed 3D. If either
of those work, please let us know.<br>
</p>
<p><br>
</p>
<p> Good luck,</p>

Good afternoon!<br>
<br>
I haven't found a solution to this problem in one of your
user threads, internet and I haven't succeeded resolving the
issue.<br>
I have installed chimera 1.15 today and it runs well when
working on the desktop. However, it would be very convenient
if I could run chimera remotely. Chimera is installed on
Centos 7, I am trying to remotely operate this PC with
Windows 10 PC using MobaXterm. When I run chimera as <i>chimera
--debug</i>:</div>
