While running OpenGL remotely should work, as you see it often doesn't.
It occasionally does work, usually when the remote version of OpenGL and
the local version of OpenGL are exactly the same.
The best solution I've seen for running Chimera or ChimeraX on a remote
Linux server is to use VirtualGL. That side steps all of the issues of
trying to do OpenGL remotely by doing all of the 3D graphics on the
Linux server and returning an image. It helps if there is a graphics
card in the Linux server. VirtualGL has to be installed on the Linux
server for that to work, and it is a little tricky to install correctly,
but it is the best solution. Contact your cluster support for help with
that. Otherwise, try making your computer exactly the same
configuration as the Linux server, same version of Linux, same graphics
driver (ie., if the server has NVidia 419, you need to have NVidia 419).
Sorry, I have to comment on the anti-social behavior of using a cluster
login node for running Chimera. I trust that was just an example or
that you're not sharing the login node with other users. If your
cluster has interactive/development nodes, those would be the right
nodes to use and it might be the case that VirtualGL is already
installed on those. If VirtualGL is installed, then run "vglrun
chimera" instead of "chimera".
All the best,
