Just need l4con or Dope, not both (xor!). So the screen goes black
because GRUB is doing the vbeset and thus switching the video mode,
which initially is black. And probably because dope and l4con step on
each others feet while trying to get access to the video memory it will
stop on boot-up. Just use one, either dope or con. BTW, it is good to
have a (virtual) serial console to see the debug messages when using
graphics because otherwise you don't really see anything if things go
wrong.
