apple_set_os kernel parameter fails #13

Closed vanya-robertson closed 5 months ago

vanya-robertson commented 5 months ago

I have followed the instructions for Enabling the iGPU. Setting apple_set_os in GRUB_CMDLINE_LINUX_DEFAULT causes glxinfo | grep "OpenGL renderer" to return the Intel card only when running the backup initramfs. When running the default initramfs, my console just fails to boot. Please advise how to solve.

what mac model is this?

Maybe try regenerating the initramfs when you boot the fallback initramfs, so the default initramfs will have any modules needed for the igpu as well

I was running mkinitcpio -P after grub-mkconfig -o /boot/grub/grub.cfg

It is a 16,1 Macbook Pro.

I was regenerating initramfs before booting into backup. When done from the backup initramfs, it worked. Why would this be?
