Re: Getting started

If you don't see Tux, the penguin, on boot up, you didn't get a working frame buffer (usually).

What is your video card?

There are a number of individual choices you need to make in the kernel config to make it all work.

Some video chip sets work better than others.

So far, I've had good luck with anything Matrox.

  Hi guys,

    Would someone please point me to a 'Getting started' URL for framebuffer
  support?

    I am running Fedora Core 4 and I have rebuilt the kernel to make sure
  FB support is in the kernel.  I have a simple FB program that I have 
  compiled but everytime I try to run it, I get:

    Error: cannot open framebuffer device /dev/fb0. - No such device rc=-1

    The open code looks like this:

        // Open the file for reading and writing
        char*  FB   = "/dev/fb0";
        int    fbfd = 0;
        fbfd = open( FB, O_RDWR);
        if (fbfd < 0) {
          printf("Error: cannot open framebuffer device %s. - %s rc=%d\n",
                 FB, strerror(errno), fbfd);
            exit(1);
        }
        printf("The framebuffer device was opened successfully. - %d\n", fbfd );

    I have done the mkdir:

    [wre00@Shrek FB]$ ls -lrt /dev/fb*
    crwxrwxr-x  1 wre00 root 29, 0 Aug 17 10:05 /dev/fb0

    Any ideas/help??
