Re: [pygame] Display set_mode FULLSCREEN hang

It seems that the pygame initialization has to be before the VideoCapture initialization. If the VideoCapture camera is created first, the pygame.display.set_mode((0,0), pgame.FULLSCREEN) will hang.
By the way, how can I specify the refresh rate of the display? For me, pygame selects a 70Hz refresh frequency, but I prefers 60Hz. 

Thanks,

Adam

ah ok.
It would be good to know the failing order... so other people can work around it... or maybe we can fix it.

    Hi Rene,

    Thanks for your reply. The little Atom board (it is a custom-built
    board) is running standard Windows XP.

    pygame.display.list_modes() returns:

    [(1280, 1024), (1280, 1024), (1280, 960), (1280, 768), (1280,
    720), (1152, 864), (1024, 768), (960, 540), (800, 600), (800,
    480), (720, 480), (640, 480)]

    The LCD is 1280x1024. I have tried to call set_mode with (0, 0),
    (1280, 1024), and (640, 480) and all getting the same problem.

    On a plus note, after a lot of tried this afternoon, I was able to
    get it to work by shuffling the order of the initialization code
    between pygame and other modules I am loading. So maybe the
    problem is with the conflicting access to resources, or something.

    I am using pygame, PIL, and a webcam module called VideoCapture.
    Hope it helps.

    Thanks,

    Adam

        hi,

        definitely sounds like a bug... but most likely in the X.

        Have you used list_modes first?
        http://www.pygame.org/docs/ref/display.html#pygame.display.list_modes

        What does your little computer say are available?

        cu,

           Hi there,

           Just wrote small code to test different screen mode. It
        works well
           on my desktop, but when I moved it to an Atom-based computer,
           there is a problem.

           The code appears to hang when I set_mode with FULLSCREEN.
        Again,
           the same code works without problem on my desktop, but not
        on this
           small Atom-based computer. Other modes works fine on both
           computers as well, as long as I don't set the FULLSCREEN flag.

           The display adapter is "Intel US15 Embedded Graphics Chipset
           Function 0".

           Any idea? Could it be a bug?

           Thanks,

           Adam
