	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 kernel normally (on /boot)
+	- use 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 Nvidia 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.
+
+	Note: for consistent gpu label, follow this comment: https://github.com/niri-wm/niri/issues/2477#issuecomment-3734221349
