    Hello there,

    I've built GLFW for my custom i.MX6 ARM platform. My basic xorg.conf has a single screen/monitor and the GLFW examples run fine. (DISPLAY=:0) So far, so good.

    When I change my xorg.conf to have two screens/monitors I can't run the GLFW examples at all.
    With DISPLAY=:0 I get -

    XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
    after 89 requests (89 known processed) with 0 events remaining.

    The desktop that was running on this display disappears after this error. I have to restart the xserver to get it back. I get exactly the same if I use DISPLAY=:0.0

    If I use DISPLAY=:0.1 to specify the second display, I get

    XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
    after 76 requests (76 known processed) with 0 events remaining.

    Anyone got any ideas what I'm doing wrong? All comments and suggestions welcome!
