## Foreword
2022-08-13 01:47:48 +02:00
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.
2022-08-12 20:46:36 +02:00
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.
## How to get Hyprland to possibly work on Nvidia
2022-08-13 19:06:18 +02:00
Install the `nvidia-dkms` driver and add it to your initramfs & kernel
parameters. Follow the information available here:

{{< hint >}}If your GPU is listed as supported by the `nvidia-open-dkms` driver,
use that one instead.

Following the wrapping instructions found on
[the Quick Start page](../Getting-Started/Quick-start#wrapping-the-launcher-recommended),
2022-08-13 01:47:48 +02:00
wrap the launcher and additionally export these:
2022-08-12 20:46:36 +02:00
```sh
export LIBVA_DRIVER_NAME=nvidia
export CLUTTER_BACKEND=wayland
export XDG_SESSION_TYPE=wayland
export QT_WAYLAND_DISABLE_WINDOWDECORATION=1
export MOZ_ENABLE_WAYLAND=1
export GBM_BACKEND=nvidia-drm
export __GLX_VENDOR_LIBRARY_NAME=nvidia
export WLR_NO_HARDWARE_CURSORS=1
export WLR_BACKEND=vulkan
export QT_QPA_PLATFORM=wayland
export GDK_BACKEND=wayland
```
2022-08-13 01:47:48 +02:00
Install `qt5-wayland`, `qt5ct` and `libva`. Additionally
`nvidia-vaapi-driver-git` (AUR) to fix crashes in some Electron-based
applications, such as Unity Hub.
2022-08-12 20:46:36 +02:00
Reboot your computer
Launch Hyprland with the wrapper.
It _should_ work now.
### Fixing random flickering
2022-08-13 01:47:48 +02:00
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.
2022-08-12 20:46:36 +02:00
Make a new file at `/etc/modprobe.d/nvidia.conf` and paste this in:
2022-08-13 01:47:48 +02:00
2022-08-13 19:06:18 +02:00
```sh
2022-08-12 20:46:36 +02:00
options nvidia NVreg_RegistryDwords="PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"
```
2022-08-13 01:47:48 +02:00
Reboot your computer and it should be working.
