--- Comment #17 from fjdegroo <felix.j.degrood at intel.com> ---
Regarding the bios, we are a power and performance group and so regularly fix
the IA/GT/Ring/DRAM frequencies to reduce run to run variance.  This is
necessary for the performance issue that we routinely chase.  Part of this is
fixing the SAGV to High in the bios.  

I reset the SAGV to Enable in the bios and this display issue went away.  I can
now see the desktop after login.

Re-enabling SAGV in the bios is a good workaround to get us unblocked. But long
term we will need a solution for getting display when SAGV is fixed.
