    Question how to create a /dev/fb0 device

    I am using an application that uses the frame buffer devices but when I run it I get this error.
    Code:
    Open /dev/fb0 : No such file or directory
    As the problem says this is because there is no such file or directory..
    so I think probably creating one will solve the problem..
    So, can anyone suggest a way to create this frame buffer device..

    I have never used it but I think you need
    Code:
    sudo mknod /dev/fb0
    but you may need some options in there as well. Have a look at man mknod for more info.

    ya now I am able to use both of the applications..
    view image as well as the pdf..
    but I am having some trouble with the resolution..
    actually the problem is only with the alignment of the ubuntu logo at the time of boot..
    its not at the center..
    so I was wondering if there is a way to align it..

    I'm having a bit of trouble with this myself. I've tried executing "sudo mknod /dev/fb0" but got "mknod: missing operand after `/dev/fb0'"
