See https://github.com/openSUSE/gfxboot/issues/7.
It doesn't start on Chromebooks as it doesn't find/can't set a video
mode.

It just hangs in there.
With kvm /dev/sdb on another machine I can see it correctly gives
resolution list.

Right, yes it does react to Esc, I can get the boot: menu with the
harddisk/linux/upgrade etc options. So it's not hanged.

Please test this one. Ideally it shows the current mode and then lets
you continue.
Anything can happen, but I'd like at least to know the mode number.

test iso 3: also list available modes
Please test this one. It should list all available modes on the first
text screen. Otherwise nothing has changed.
Please post a screenshot of the mode list (provided there is anything).

We have image! Sorry for bad colors, they are normal red/green/blue for
all the blocks.
The text is ip 26d: 2010b0a9.4 (ie the '1' is what's barely visible
under green color in the photo)

Ok, what you see there is the debug window. You can single-step through the code
with 'Enter', 'ESC' leaves the debug mode. The dots were just sprayed all over
the graphics framebuffer.
If you go two steps further with 'Enter' (provided it works), what number appears
in the data window (upper left)? (The ip in the bottom left should show '27a'.)

Below in the bottom box there is also:

ip 27a: 45.7
Let's continue after next week then probably.

Installer doesn't show up on some Chromebook

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.
