The three numbers in the list represent, in order:
  - the horizontal resolution
  - the vertical resolution
  - the colour depth, i.e. the number of different colours that can be
displayed at each pixel.

You can also see colour depth expressed in terms of bits-per-pixel or
bytes-per-pixel, e.g. 256 is 8 bits-per-pixel since 2^8 (2 raised to
the eighth power)  = 256.

Unfortunately, I can't solve this problem. I do have one suggestion -
maybe you can tell X not to use the framebuffer, since the console is
now set to use the framebuffer.

Not that I know of, and I don't know why this works...

I think someone else mentioned removing the "splash" option from Grub,
so try that.

I think your problems stem from the non-standard hardware that is used
in most laptops, which is not fully supported in Ubuntu (and probably
not in most Linux distros).
