[Bug 1530530]

[Siro-3]

You are right.
I got confused looking at the code:
pixel_bits		db 0		; pixel size (8 or 16)
color_bits		db 0		; color bits (8, 15 or 16)

This should be fixed.

SeaVGABios advertises 24bpp as the panel does support 24bpp, even though
the VBE format should be 32bpp. I'll send a fix to SeaBIOS.

Bug description:
  I downloaded Ubuntu Wily 15.10, then copied into an USB drive in order to use that to install Ubuntu on my Chromebook Pixel 2.
  After selecting the drive to boot from, I only get a terminal that shows up the following lines:

  graphics initialization failed
  Error setting up gfxboot
  boot:

  Same happens with any *buntu ISO image ( I tried KDE and XFCE as well).
  At this point, I tried to download the  Debian8 ISO image and I noticed that the installer doesn't recognize the video size, too but then asks for the user to manually select a suitable video format from a list of options. >From that point on, I was able to install Debian on the chromebook.
