<p>Dear Greg, <br>
</p>
<p>Thank you very much for the prompt reply. <br>
</p>
<p>About ssh -X, indeed putting the compatible libGL.so from local
machine<br>
to Chimera's lib folder does the trick. <br>
</p>
<p>About Nice DCV, I have contacted Nice DCV developers and will <br>
let you know if the problem is solved. <br>
</p>
<p>With best wishes, <br>
Mihajlo <br>
</p>

<p>Hi Mihajlo,</p>
We don't have any experience with Nice DCV, perhaps some other
user on the mailing list can help. But guessing at possible
problems, make sure that Chimera is displaying locally in Nice
DCV virtual machine (the DISPLAY environment variable should be
":0"), and the remote display is done using the Nice DCV client.<br>
<br>
If, instead, you're using X11's remote display capability, then
you wouldn't need to use Nice DCV, any virtual machine
technology would do (or not do) -- the trick there is to have
compatible OpenGL drivers on both the virtual machine and your
local computer (running the X11 server). Assuming compatible
versions of Linux on both ends, you could copy libGL.so from
your local machine to the Chimera's lib directory on the remote
machine, and it should work.<br>
<br>
Good luck,<br>
<br>
Greg<br>
