I have the same problem. Attempting to link against /usr/lib/nvidia-375/libEGL.so.375.39, /usr/lib/x86_64-linux-gnu/mesa- egl/libEGL.so.1.0.0, and /usr/lib/nvidia-375/libEGL_nvidia.so.375.39 instead of -lEGL does not fix it. It does not fix it as in eglGetDisplay() still returns EGL_NO_DISPLAY.
/usr/lib/nvidia-375$ ls -l *EGL* lrwxrwxrwx 1 root root 23 Mar 17 04:31 libEGL_nvidia.so.0 -> libEGL_nvidia.so.375.39 -rw-r--r-- 1 root root 1079216 Jan 31 22:06 libEGL_nvidia.so.375.39 lrwxrwxrwx 1 root root 11 Mar 17 04:31 libEGL.so -> libEGL.so.1 -rw-r--r-- 1 root root 77264 Jan 31 20:35 libEGL.so.1 -rw-r--r-- 1 root root 20608 Jan 31 20:35 libEGL.so.375.39 It appears that libEGL.so.1 itself is an ELF: /usr/lib/nvidia-375$ file libEGL.so.1 libEGL.so.1: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-367 in Ubuntu. https://bugs.launchpad.net/bugs/1674677 Title: eglGetDisplay(EGL_DEFAULT_DISPLAY) returns EGL_NO_DISPLAY Status in nvidia-graphics-drivers-367 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-375 package in Ubuntu: Confirmed Bug description: I am using EGL to obtain offscreen rendering contexts, but upgrading this package today broke my application. I have written a small test case, that I expect to print "PASS": ``` #include <EGL/egl.h> #include <iostream> int main(int argc, char **argv) { EGLDisplay eglDpy = eglGetDisplay(EGL_DEFAULT_DISPLAY); std::cout << ((eglDpy == EGL_NO_DISPLAY) ? "FAIL" : "PASS") << std::endl; } ``` Build with e.g. `g++ egl_test.cpp -lEGL`. Using nvidia-375 (375.39-0ubuntu0.16.04.1), this test program will print "FAIL", because `eglGetDisplay(EGL_DEFAULT_DISPLAY)` returns `EGL_NO_DISPLAY`. If I install the 375.39 driver using Nvidia's installer, the test passes, so I think it is not an upstream issue.
