Jeremy_Gordy; A disappointment !
coldraven has a good point - input most appreciated !- ,
Might try the graphics in 2D mode ? and see what results ?
Others may have a better solution, but, Ya want to revert back to the 12.04 kernel ?
Doing so, might be a chore to maintain grub in the future at this point.
I do not know that there is a means to remove the HES once enabled (??).
there just ain't a good solution
