<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>
