--- Comment #1 from gravity6@gmx.de ---
When booting with grub and linux i use the grub setting
"GRUB_TERMINAL=3Dconsole".
At the grub console by pressing "c" and typing "videoinfo" there is an empty
list. The guess is, that there is no gop video mode available. Furthermore:
if once queried the modes via 'videoinfo' at grub, the following boot and
reboots are in 'blind mode' as grub says. First Video output comes when the
nvidia xorg driver loads. To get linux kernel boot messages back, the noteb=
ook
has to be shutdown and started again. Maybe linux kernel parameter reboot=
=3Dcold
leads to the same.
