Subject: [Linux-fbdev-users] Getting started

Hi guys,

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

  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);
    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??
