/bin/sh: 1: glxinfo: not found
libGL error: MESA-LOADER: failed to open nouveau: /opt/schrodinger2024-2/maestro-v14.0/lib/Linux-x86_64/gl/nouveau_dri.so: cannot open shared object file: No such file or directory (search paths /opt/schrodinger2024-2/maestro-v14.0/lib/Linux-x86_64/gl, suffix _dri)
libGL error: failed to load driver: nouveau

​Error: x server has no opengl glx extension maestro
Fix: After I executed this command, it worked fine:
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
 
But we need to open Maestro in the shell, for example:
cd <your path>/schrodinger20xx-x
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
./maestro
 
Or directly modify the Maestro startup script
vim ./maestro
Add to the first line
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
I tried the following and it worked

I referred to the following links
https://github.com/conda-forge/ctng-compilers-feedstock/issues/95

What worked for me is to add the following in the .bashrc script:export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
source .bashrc 
 
Schrodinger response:
The error usually indicates that you have not installed drivers with hardware accelerated OpenGL. Try launching Maestro with the -SGL option$SCHRODINGER/maestro -SGL​

Please refer to the following KB articles for more information:
I just installed the latest version of Schrödinger software on a new computer and I am receiving some OpenGL GLX errors. What do they

Can I run Maestro on a remote machine and display to my local machine?
