GRUB shows up on my external monitor, but never on the laptop monitor
@jayeff I have an issue where what you described is exactly what is happening.
I have a dual boot system with Ubuntu and windows 11, and with GRUB as the bootloader.
When I start the computer with the external monitor connected, GRUB shows up on my external monitor, but never on the laptop monitor, which is always a black screen, whether or not the external monitor is connected.
However, Fn+F9 doesn't have any effect. Any chance you have other ideas on what to try?
Questa è una buona domanda?

When the laptop is on with a display on the external monitor, try shining a torch (flashlight) at an angle close to the laptop's screen and check for any images.
They will be very faint so they may be hard to see if they're there.
If they are there then there is a backlight problem in the laptop display. Either in the display or the motherboard.
What is the model number of the laptop.

I tried shining the flashlight method; there seems to be no display whatsoever.
The laptop is an ASUS ROG TUF FX 504
