Hi!

This problem also happens with the latest non-PPA Nvidia drivers, but I assume 
this is where the developers hang out. The problem is that the Nvidia EGL 
driver need a JSON file to find extension libraries, and it looks in 

/usr/share/egl/egl_external_platform.d/

but the Ubuntu packages put the files in 

/usr/share/glvnd/egl_vendor.d/

Copying the JSON files over to /usr/share/egl/egl_external_platform.d/
makes everything work again.

The context is that Qt-based compositors (and Weston with the EGLStreams 
patches) suddenly stopped working on Nvidia hardware after an update.

Regards,
