NVIDIA boot option in UEFI live USB boot hangs

[joekamprad]

if using refind you need to add boot kernelm options in another way so no need to add anything to grub if you do not use grub … but the options will not run if not added to be use don boot with refind…
the file refind uses is:

/boot/refind_linux.conf

or wherever you put the refind files …

I was looking at the Fedora 37 grub.cfg for a working NVIDIA boot. I’m not seeing the ibt=off entry:

Curious what’s different about how Endeavour is booting / configuring the kernel.

[joekamprad]

we do not do any special boot or even kernel.

Compared to arch at least…

And the issue with the need to disable IBT is arch specific so it is not affecting fedora they have different kernel… and could be different stuff not loaded or loaded with the kernel images… initrd in different ways… it is not only possible to do so from grub kernel line. the could be also inside kernel image or modprobe setup
