17 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
19 assume is a good one, the intel fb device cannot change the video mode
20 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.

24 I typically include both vga= and video= lines in my grub command to get
25 this to work.
