    I tried with 10.2 dev, but I have the same issue.


    The aceleration run if you edit /etc/adobe/mms.cfg

    and you write inside ;

    Your issue could be a duplicate of one of these. You might get some more information by reading those bug reports.

Anyway I'm wondering if I should leave OpenGl till I can get a workable KDE frameworks 5 desktop running on Wayland up.
    Run
    Code:
    glxinfo | grep OpenGL
    and it will print some information about your maximum supported version of OpenGL, even if software rendering is used it shouldn't be 1.4.

    Its Glx that is at version 1.4 not my systems implementation of OpenGl. From what I've learnt in the last day GlEW the GL extension Wrangler is the standard way to use later GL functionality. GLEW determines their availability at runtime rather than at compile time. This means that GLX, doesn't have to be updated every time that Opengl adds new functionality.

    Why can't you just use opengl native? Yea, you can't assume EGL, but you can assume nowadays OGL 3+ or even better GLES 2+. IE, include glew and gl.h, not glx.h. GLX is just a couple additional functions to extend openGL on X.

    I'd love to get rid of GLX. Xlib is awful to work with. But from what I've read even if you're using XCB you have to use some xlib functions to get an OpenGL context. So how do I open a Window and get a context? And How do I access my input?

    You really should be using SDL2 to abstract away all that crap. Then you don't have to worry about glx, egl, or even wgl on windows.

    I believe calling glx directly will only give you the stuff that it can send over X across the wire remotely (in an indirect context), which is extremely difficult with a lot of the newer GL functionality, so they haven't bothered even trying to support all that stuff directly.
