Right; hybrid graphics switching is not supported in Ubuntu at this
time. There are various experimental solutions out on the interwebs you
could try, but we only support booting with the base graphics (sandy
bridge).
One work around you could try is blacklisting the i915 module from being
loaded. Theoretically that should permit nouveau to pick up the
graphics and go. Again though, this is not a supported configuration.
** Description changed:
Ubuntu 12.04 live (daily 23.12.) fails to boot when nvidia/nouveau is
the primary gfx @ bios. Using Sandy Bridge gfx it at least boots, but
does not use the nouveau stuff for much then. Most likely assigned to
wrong package, but attached information might be interesting for
developers regardless.
