it may be pppc specific, but i also note that cavsfan is using amd64 and

Just to correct my post #55, since on the logs nouveaufb looks like it
is loading fine for you then you can use the fbdev driver with that.
All you need to do is create an xorg.conf that specifies fbdev (don't
use the nomodeset parameter). If you still get 8 bit graphics then you
need to increase

I think you may be better served with a new bug, this was quite specific to
nvidia hardware that couldn't boot to a live session or installer normally but
could if removing splash or using nomodeset.

I downloaded the beta 2 today twice from 2 sources and md5sum checked OK.
But, I could not install or do anything with it. The video was just garbage
with no options displayed.
Had to press reset on PC.
This is the ubuntu-12.10-beta2-desktop-amd64.iso version,
I have an nvidia geforce 9800 GT.
Using 20120929 on a GeForce FX Go5200, no luck.
For grins, I tried various boot parameters and got nouveau's output to
dmesg and the Xorg log for each of them.
Of these, the following failed to produce a visible X:

I also solved my problems with today's ISO (http://cdimage.ubuntu.com

with a live USB key on my PC with an Nvidia graphic card.

Nomodeset generally works but leaves the live session in low graphics. Removal

maintains proper grahics in the live session.

I should note that as of recently using nomodeset will allow the installer

Other users with various nvidia hardware report the same.

I've gone ahead tried the nomodeset option multiple times. (7)
Twice it worked fine to produce a workable live session/installer
