[Solved] Settings in /etc/default/grub not possible

Hello,

I want to activate my NVidia graphic card using the article at https://linuxiac.com/nvidia-with-waylan … tup-guide/. I already enabled a couple of parameter but I am not  able to enable DRM because the file /etc/default/grub does not exist. When I search for grub in pacman "pacman -Ss grub" I am able to see that grub is not installed which means (for me) that I don't use grub. I am currenty not sure what is the app that is used for booting my arch linux and unfortunately I don't know how I could find out that information.

The mentioned article requires to append “nvidia-drm.modeset=1” in GRUB_CMDLINE_LINUX_DEFAULT.

- How can I add the line if no /etc/default/grub is available ?
- How can I find out what is used on my system ?

BR

Are you using systemd-boot then? Just add what you need there, should be /boot/loader/entries/arch.conf (add in options line).
Or install grub if you want then proceed with grub stuf.

How did you set this system up? Usually people know what they use because they chose it, installed it, and configured it as that's how Arch works.

Usually I do know what I configured when installing an OS but this was nearly 2 years ago and I tested many things, so unfortunately I am not sure what I configured.

Try `bootctl status`.  Assuming EFI is in use the "Boot Loaders Listed in EFI Variables" section of the output may help.
