The T480 is 8250u+MX150 and cannot start normally when using efi, the screen is black and there is no picture, but there is a backlight display, how to solve it?

This could be related to the MX150 graphic card, you need to disable it, this can help you:

Or this repo has the SSDT-OFFDGPU.aml that could help you.

Add this to your ACPI folder and your config.plist (make sure is enabled)

If you flashed your BIOS you can disable it in the Advanced Menu.
