Please help, I have been going around and around with this problem but cannot seem to make any headway. I hope that one of you OpenGL EGL experts can help. [image: :slight_smile:]
I have created a program that uses OpenGL EGL (version 1.5) with OpenGL 3 that successfully renders an offscreen triangle and saves it to an image file (PNG) when I ssh *without* X11 forwarding on my Linux (Ubuntu 22.04) machine. However when I try the same thing using ssh *with* X11 forwarding enabled I get the following EGL error when I call eglInitialize(…): 12290 (I *think* is EGL_BAD_ACCESS). This seems really weird and I hope it is something simple that I am just not currently seeing. I really like using OpenGL with EGL but need a way to remedy this situation if possible. Is there a way for EGL to determine if X11 forwarding is being employed and to ignore it or some other solution? The snippet of relevant C++ code follows, with area where error occurs marked: #include <iostream> #include <cstdlib> #include <EGL/egl.h> #define EGL_EGLEXT_PROTOTYPES #define GL_GLEXT_PROTOTYPES #include <EGL/eglext.h> # include <GL/gl.h> ... EGLDisplay display = eglGetDisplay(EGL_DEFAULT_DISPLAY); if(display == EGL_NO_DISPLAY) { std::cerr << "Failed to get EGL display: " << eglGetError() << std::endl; exit(EXIT_FAILURE); } EGLint major; EGLint minor; if(eglInitialize(display, &major, &minor) == EGL_FALSE) { // ERROR 12290 is generated here std::cerr << "Failed to initialize EGL: " << eglGetError() << std::endl; exit(EXIT_FAILURE); } ... Any help would be greatly appreciated.
