    This is not an OpenGL extension, its a GLX extension so none and no unless LXDE starts using a OpenGL based compositor.

    Because of a bug in the way buffer_age has been used in the past (it worked with nvidia because their driver was broken; they fixed it and then we noticed that it was broken and fixed it as well). But that patch is in the clutter-1.16 branch and already in Fedora and Arch.

    thanks for explanation... lxde doesn't use any opengl compositor, so which compositor it uses?

    But you can always use
    Code:
    compton --backend glx
    with any non compositing window manager.

    They have some nice information too:

    I understand, thank you.

    Heads up:
    Some relevant packages have been submitted to Arch AUR
