 Could you post a picture somewhere ?

 I have a laptop which have efifb problem, what I need to do is (at
loader prompt) :

 gop set 4 (to switch to a different mode)
 gop set 0 (switch to the correct mode)

 You can gop list (iirc) to checks the available mode.

 The problem is that we are mixing serial and gop in loader.efi and
when you set one mode in serial (or for SIMPLE_TEXT_PROTOCOL) is can
mess the graphical mode.
