This is the only correct syntax for the intelfb device, because of |

these log messages. I assume this is a laptop (or else your intelfb is |
18 |
very confused). For some reason that I don't fully understand, but |

assume is a good one, the intel fb device cannot change the video mode |

on a laptop display. The vga parameter actually gets the kernel to |
21 |
change the video mode much earlier, so the intelfb driver can keep using |
22 |
the same one. |

I typically include both vga= and video= lines in my grub command to get |

this to work. |
