Comment 5 for bug 1733136

It seems there's an error in eglGetDisplay(), but I don't know why.

journactl -b shows:

One difference between my artful and bionic installations is that bionic is missing the links:

/usr/lib/x86_64-linux-gnu/libEGL.so -> mesa-egl/libEGL.so
/usr/lib/x86_64-linux-gnu/mesa-egl/libEGL.so -> libEGL.so.1.0.0

However, creating these manually doesn't fix the problem.

The library config seems good:
