on current GNU Guix System, eglGetDisplay returned EGL_NO_DISPLAY.

[Andy Tai]

Hi, in an up to date GNU  Guix system that I have running in a VM on a
Fedora host (via KVM), the eglGetDisplay() call always returned
EGL_NO_DISPLAY.  Note OpenGL is working; for example  glxgears runs
fine.

On recent releases of Fedora or Ubuntu 24.04, the same code, I have no
such problem.

I wonder if the graphics stack on GNU Guix system is behind the other
distributions. The version shows the Mesa driver at 24.0.2 so it is
fairly up to date.

Any info or clue is appreciated.
