This is probably because the libEGL it finds is not the nvidia driver's version, nor is it a GLVND version that dispatches to nvidia's. Please let me know the output of ls -l /usr/lib/x86_64-linux-gnu/*GL*, and also what linux distribution/version you're using.

You seem to have a version of libEGL that doesn't match everything else (dated 2015, not 2018), and this is the one that ldd says is being used. I'm not sure how the system has ended up like this. Reinstalling the nvidia driver might fix things. libEGL.so should be installed as part of the driver package, and is then a thin wrapper that uses libGLdispatch to call through to libEGL_nvidia. Unfortunately the _nvidia version doesn't directly export the relevant symbols, so you probably can't just LD_PRELOAD it (though it may be worth trying, if you can't fix the installation).

Thanks for your help! The LD_PRELOAD trick works well
LD_PRELOAD=/path/to/new/libEGL.so.1.1.0 tests/square_test.py

Hi~
I also met the same problem.
I installed nvidia-driver, and got corresponding pkgs:

And I set

export LD_PRELOAD=/usr/lib/nvidia-410/libEGL.so.1.1.0

in ~/.bashrc

but I still get this error:

Can anyone help?
Thanks in advance!
