--- Comment #7 from Pierre Moreau <pierre.morrow at free.fr> ---
I've been playing a bit with the apple-gmux driver to check if it was the one
responsible but without success; the only difference between before suspending
and after resuming being GMUX_PORT_SWITCH_GET_DISPLAY which used to be 24
before suspending, and equals to 0 when resuming (and the discrete card coming
back online, but that was already dealt with). So, without Nouveau loaded, the
screen will stay black.

However, if using patches from
https://bugs.freedesktop.org/show_bug.cgi?id=27501#c29, the screen resumes
