    Problem with xlibmesa 1-10

    Hello everyone,
    I am having problems trying to execute programs when activating the alpha (they usually crash in the very
    glutCreateWindow("Whatever");
    line) while using the 1-10 version of mesa. the problem seems to appear when you try to use the GL_ALPHA (or in other machines the GL_STEREO), in the glutInitDisplayMode. I mean, the program runs without the GL_APLHA in the glutInitDisplayMode line, but if you add it it simply crashes with a
    a.out: freeglut_window.c:300: fgOpenWindow: Assertion `window->Window.VisualInfo != ((void *)0)' failed.
    Aborted
    With the 1-08 version everything seems to be running fine.

    The libraries being used are:

    freeglut3 2.2.0-8
    xlibmesa-gl 4.3.0.dfsg.1-10
    xlibmesa-glu 4.3.0.dfsg.1-10

    Try to use the latest Mesa (6.x), and the glut package providen with the Mesa demos.

    Hope this will help.

    Finally the problem was "solved" after changing the OpenGL libraries from the mesa to the Nvidia ones. Besides that, we had to take out the GL_ALPHA in the
    glutInitDisplayMode. The transparency keeps working, (it shouldn't but it does). The program runs in a really weird form but (lots of bugs that shouldn't be there and very very strange things),but well, it is running!
