Greg,

Looks like we have to copy the data or sshfs to the Amazon Workspace X11 is the only X11 client that displays Chimera from a Linux server or get the scientist a Linux workstation.

Macintosh XQuartz was what was crashing Chimera from my RHEL 7.6 EC2.    

Chimera crashed MobaXterm on Windows when displaying from the RHEL 7.6 EC2 as well.

Thank you very much for all your help.

Chimera works best when it is running directly on your local computer.  So you would ideally copy the data you want to visualize from the AWS Workspace (i.e, cloud) to your local disk to visualize it.  Or, perhaps, you could use a program like sshfs to remotely mount your data.  And on your local computer, if you have NVIDIA graphics, you should install the proprietary NVIDIA graphics driver; if you have AMD graphics, both the open source and the proprietary drivers should work; and if you have Intel graphics, your only choice is the open source driver.

However, remotely displaying, like you are trying to do, should work if your local computer is running Linux.  Since the AWS Workspace has open source drivers installed, you might need to switch your local graphics to the open source version.  Or copy the libGL.so from your local computer, to the AWS Workspace.  That is, the two drivers need to be compatible.

In the AWS workspace, run the glxinfo problem to see what its OpenGL setup is like.  glxinfo is in the glx-utils package.

    Good luck,

Dear ChimeraGurus,

I'm trying to get Chimera 1.13.1 working on RHEL 7.6.  I have it working on Amazon Linux 2 in AWS Workspace.

Does anybody know what the yum package dependencies are for REHL or CentOS 7?

Chimera is crashing after "initializing graphics" as per the --debug command line option.

I know that I had to do this to fix a few errors:

yum install tkinter
yum install tk-devel
yum install libXScrnSaver
yum install mesa-libGL mesa-libGL-devel
yum install firefox 

Kindly advise.

Best regards,
