    Question Upgrade to 8.58.2 and openGL problems

    I've just upgraded an X86_64 box from Fedora 8 to 10.
    fglrx is now 8.58.2

    I have an openGL application that used to work fine but now has two problems. I'm using gtkglext-1.2.0

    1) Double buffering no longer seems to work.

    Despite using
    glconfig = gdk_gl_config_new_by_mode(GDK_GL_MODE_RGB | GDK_GL_MODE_DEPTH
    | GDK_GL_MODE_DOUBLE);

    a call to gdk_gl_drawable_is_double_buffered() returns FLASE.

    I use "unique colour" picking, and without double buffering the scene drawn for picking is appearing on the display!

    2) I can only open one openGL application at a time, the second one hangs without opening it's window and using 100% CPU.

    Any help appreciated.

    Bad form to reply to my own post....

    But....

    I noticed the files section in my xorg.conf was empty, now I've filled it in the problems seem to have gone away !

    Section "Files"
    ModulePath "/usr/lib64/xorg/modules/extensions/fglrx"
    ModulePath "/usr/lib64/xorg/modules"
    EndSection
