   Apr 25, 2013 · First things first, you should not access the OpenGL context outside of the rendering thread. I assume you have looked at these already, but just to make sure read up on the AssetManager wiki article, which talks a bit about how to use the AssetManager for asynchronous managing of assets.

   Jun 1, 2017 · If you use the auto-detect for your graphics card type, I think it should just install automatically. If you do get a zip file as the download, use 7zip to open the file and extract it to a folder on your desktop, then look in that folder for a file called "setup" or maybe"install". http://www.7-zip.org/download.html.

   You can use these vendor specific functions: wglGetCurrentContext() on Windows, aglGetCurrentContext() on OSX, glxGetCurrentContext() on unixoid systems with X and. eglGetCurrentContext() on GLES based systems like iOS or Android. They all return NULL (except for eglGetCurrentContext, which returns EGL_NO_CONTEXT) if there is no valid context ...

   Dec 1, 2016 · Re: Graphical driver issue No OpenGL context found in the current thread. That "xrandr", yes. The idea is that your current resolution exceeds limitations of the IGP (thus please notice the "-l" switch)

   Can OpenGL context be used only from a rendering thread?

   • You did claim that the OpenGL context could be used from the rendering thread only, implying that only the thread that did create the context could use it. BTW: you can create several OpenGL contexts on the same drawable with shared object namespaces and attach each to a own thread. This gives you multithreading.

   Can a single thread access OpenGL context?

   • The context itself can only be access by a single thread at a time unless you want to try and use locking to achieve it. However, that defeats the whole point. You did claim that the OpenGL context could be used from the rendering thread only, implying that only the thread that did create the context could use it.

   Is there a way to check for a valid context in OpenGL?

   • printf("You tried to call a rendering function but no OpenGL context was found!"); Is there a way to check for a valid context within OpenGL without getting a segfault? You can use these vendor specific functions: They all return NULL (except for eglGetCurrentContext, which returns EGL_NO_CONTEXT) if there is no valid context currently active.

   How do I bind OpenGL context to a thread?

   • You need to call glfwMakeContextCurrent to bind the OpenGL context to your thread. There's a working example on the LWJGL website as well. OpenGL contexts are bound to a thread when they are created, so they can only be used from that thread. See the answer here.

   Jan 3, 2018 · It is recommended that you call wglMakeCurrent(NULL, NULL) if GL context is current on another thread, then call wglMakeCurrent(dc, glrc) in the other thread. Example : // Thread_1: wglMakeCurrent ( NULL , NULL ); WaitForThread2 (); OrDoSomeCPUJob (); wglMakeCurrent ( dc , glrc ); // Thread_2: wglMakeCurrent ( dc , glrc ); DoSome_GL_Work ...
