EFI-STUB, FB and Nvidia fail

[stifler83]

Hi guys,
how can i configure fb (nvidia) using efi stub? I do not know which parameters to enter in BUILT-IN KERNEL COMMAND or what other parameters I have to enable.

Can somebody help me?

.... same question here - experimenting with efi starting my Apple Mac-Mini:
I can here some noise of the harddisk started by the kernel.efi. But no visual output. I only can reboot by using the special key kombinations ...

Works now.
I did some .config change to my kernel yesterday. But I don't know for sure what exaclty is needed,
here the diff:

< CONFIG_CMDLINE="root=/dev/sda7 init=/usr/bin/systemd quiet nomodeset"
> CONFIG_CMDLINE="root=/dev/sda7 init=/usr/bin/systemd quiet"
Efi using a framebuffer needs a modeset?

> CONFIG_ACPI_VIDEO=m
I don't know if needed ....

CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
CONFIG_FONTS=y
CONFIG_FONT_8x16=y
CONFIG_FONT_10x18=y
CONFIG_NLS_CODEPAGE_437=y
CONFIG_NLS_CODEPAGE_850=y
Does efi need these fonts and codepages in kernel?

< CONFIG_IO_DELAY_NONE=y
> CONFIG_IO_DELAY_0X80=y
< CONFIG_DEFAULT_IO_DELAY_TYPE=3
> CONFIG_DEFAULT_IO_DELAY_TYPE=0
Does efi need more delays?

For sure efi needs all of it:
CONFIG_RELOCATABLE=y
CONFIG_EFI_PARTITION=y
CONFIG_EFI=y
CONFIG_EFI_STUB=y
CONFIG_FB_EFI=y
CONFIG_EFI_VARS=m
but EFI_VARS. I could use EFI_VARS to manipulate the next boot?
Howto?
When "modprobe efivars" there are many entries appearing at /sys/firmware/efi
It seems all binary. I fear to get in that no-boot state we heard all of, if I begin to manipulate these entries.
