About ssh -X, indeed putting the compatible libGL.so from local machine to Chimera's lib folder does the trick. About Nice DCV, I have contacted Nice DCV developers and will let you know if the problem is solved. With best wishes, Mihajlo On 04/20/2018 07:54 PM, Greg Couch wrote:
Hi Mihajlo,
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.
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.
Good luck,
Greg

Dear Chimera users and developers,
We are trying to run Chimera remotely on our cluster via Nice DCV visualization software:
https://www.nice-software.com/products/dcv
This package provides GPU acceleration for OpenGL and DirectX applications. It indeed works for most of apps, however with Chimera we get the following startup error
X Error of failed request: GLXBadContext Major opcode of failed request: 152 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 73 Current serial number in output stream: 73
Our cluster visualization node has nvidia GeForce GTX 1080 Ti cards and nvidia drivers 384.81
Chimera works if we use software mesa rendering, but it would be great if we can make it work remotely with hardware rendering.
