Nvidia

Foreword

There is no official support for Nvidia. Unfortunately, their drivers are so messy, and their products so random, that it’s impossible for us to help if these instructions don’t work fully.

Every card seems to be random, and might work perfectly, or not work at all.

Nevertheless, it’s recommended to at least try this tutorial.

Hyprland Nvidia Patch (Arch only) (Unofficial)

hyprland-nvidia (AUR)
hyprland-nvidia-git (AUR)

Hyprland Nvidia Patch is NOT an official patch and is not maintained by us. If you have any concerns (updates, broken pkgbuild, etc), you should contact the maintainer.

nvidia-dkms is still required to run this patch, Install the nvidia-dkms driver and add it to your initramfs & kernel parameters before running. You should still however read the content below to make sure the patch is properly working and to avoid any bugs/crashes.

How to get Hyprland to possibly work on Nvidia

Install the nvidia-dkms driver and add it to your initramfs & kernel parameters.
For people using systemd-boot you can do this adding nvidia_drm.modeset=1 to the end of /boot/loader/entries/arch.conf. For people using grub you can do this by adding nvidia_drm.modeset=1 to the end of GRUB_CMDLINE_LINUX_DEFAULT= in /etc/default/grub, then run # grub-mkconfig -o /boot/grub/grub.cfg For others check out kernel parameters and how to add nvidia_drm.modeset=1 to your specific bootloader.

in /etc/mkinitcpio.conf add nvidia nvidia_modeset nvidia_uvm nvidia_drm to your MODULES

run # mkinitcpio --config /etc/mkinitcpio.conf --generate /boot/initramfs-custom.img (make sure you have the linux-headers package installed first)

add a new line to /etc/modprobe.d/nvidia.conf (make it if it does not exist) and add the line options nvidia-drm modeset=1

More information is available here: https://wiki.archlinux.org/title/NVIDIA#DRM_kernel_mode_setting

If your GPU is listed as supported by the nvidia-open-dkms driver, use that one instead. Note that on a laptop, it could cause problems with the suspended state when closing the lid, so you might be better off with nvidia-dkms.

To get multi monitor to work properly on a hybrid graphics device (a laptop with both an Intel and an Nvidia GPU), you will need to remove the optimus-manager package if installed (disabling the service does not work). You also need to change your BIOS settings from hybrid graphics to discrete graphics.

Export these variables in your hyprland config:

env = LIBVA_DRIVER_NAME,nvidia
env = XDG_SESSION_TYPE,wayland
env = GBM_BACKEND,nvidia-drm
env = __GLX_VENDOR_LIBRARY_NAME,nvidia
env = WLR_NO_HARDWARE_CURSORS,1

If you encounter crashes in Firefox, remove the line env = GBM_BACKEND,nvidia-drm.

If you face problems with Discord windows not displaying or screen sharing not working in Zoom, remove or comment the line env = __GLX_VENDOR_LIBRARY_NAME,nvidia.

Install qt5-wayland, qt5ct and libva. Additionally libva-nvidia-driver-git (AUR) to fix crashes in some Electron-based applications, such as Unity Hub.

Reboot your computer

Launch Hyprland.

It should work now.

Fixing screensharing / screenshots

Apply nvidia patches to the wlroots in subprojects/wlroots before building. See patch and hyprland-nvidia-git’s PKGBUILD.

Fixing random flickering, method 1

If you take a look at the wlroots patches in the nix flake you will find a one-line patch:

substituteInPlace render/gles2/renderer.c --replace "glFlush();" "glFinish();"

What this means, for non-nix users, is you have to (before building) go to subprojects/wlroots/render/gles2/renderer.c and replace all occurrences of glFlush() with glFinish(), and then compile Hyprland as usual.

Fixing random flickering, method 2 (nuclear)

Do note though that this forces performance mode to be active, resulting in increased power-consumption (from 22W idle on a RTX 3070TI, to 74W).

This may not even be needed for some users, only apply these ‘fixes’ if you in-fact do notice flickering artifacts from being idle for ~5 seconds.

Make a new file at /etc/modprobe.d/nvidia.conf and paste this in:

options nvidia NVreg_RegistryDwords="PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"

Reboot your computer and it should be working.
