Take the 2-minute tour ×  When I boot my PC with both Windows
and Ubuntu installed: I always get the exact message "Input not
Support" without the -ed flashing on my VOC monitor. GRUB does
not show so I can't reach Windows. I have tried blindly pressing
the "down" key and "Enter" but it yields no response. I have an
NVidia card with the extra 3D graphics driver applied also.
additional comment: Same here. sshd is running, I can log into
the system remotely from another PC, everything is working fine;
just I can't see anything on the monitor that is directly
attached. I guess somewhere within grub configuration there must
be something to set the video output resolution, but where ???
