How to set up CoreCtrl

Hi there,

I installed CoreCtrl, I read the instructions on how to
get Full AMD GPU controls, from here,

I don’t want to mess with my Grub, so I used Grub Customizer, I added the

GRUB_CMDLINE_LINUX_DEFAULT= amdgpu.ppfeaturemask=0xffffffff

I assumed it has to be the exact line “GRUB_CMDLINE_LINUX_DEFAULT”
and not just “GRUB_CMDLINE_LINUX”; so I added it at the end. (maybe that is my mistake?)

I typed in

grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Because that is where the Customizer says Grub is located. I got no errors,
I rebooted.

But when I go into CoreCtrl, I still get this.

No more extra controls than I had before.

I leave a neofetch.
