# Troubleshooting

Some fixes we've found for possible issues.

## Not enough space in EFI partition

https://wiki.archlinux.org/title/EFI_system_partition#Typical_mount_points

- mount the EFI partition on /mnt/efi instead
- install refind (e.g. refind-install in chroot)
- install kernel normally (on /boot) (e.g. pacman -S linux)
- config refind to point to it
- don't forget to fix fstab accordingly

Here's my (luxmiyu) refind menuentry for reference:

```c
menuentry "Arch Linux" {
   icon /EFI/refind/refind-theme/icons/os_arch.png
   volume "arch miyu"
   loader /boot/vmlinuz-linux
   initrd /boot/initramfs-linux.img
   options "rw root=UUID=9d0ab243-1d12-4db4-a4e4-4020517e9b6a loglevel=3 nvidia-drm.modeset=1"
}
```

## Niri Screen Tearing

https://github.com/niri-wm/niri/issues/2477

Add this to your niri config:

```c
debug {
    // wait-for-frame-completion-before-queueing
    render-drm-device "/dev/dri/renderD129" // note renderD129 is my NVIDIA GPU, yours can be different!
}
```

Choose either `wait-for-frame-completion-before-queueing` (can introduce input lag), or `render-drm-device` to render exclusively on selected gpu.
