I'd like to disable video output completely. What's the easiest way to do that?
I've tried switching to a serial terminal on ttyS2, but I don't see any grub output over serial and I still get grub over video. (I do get serial activity once the kernel starts, so I know the serial port is ok.)
Hardware is a Fitlet2 embedded PC, connected to a 4k TV over HDMI. (The 4k is the problem--I want to force it to 1920x1080, and I can't seem to find a way to do that in grub, either.)
thanks! newell _______________________________________________ Help-grub mailing list Helpemail@example.com https://lists.gnu.org/mailman/listinfo/help-grub
