## 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.
|
|
|
|
## How to get Hyprland to possibly work on Nvidia
|
|
|
|
Install the `nvidia-dkms` driver and add it to your initram & kernel parameters,
|
|
follow the information available here:
|
|
[https://wiki.archlinux.org/title/NVIDIA#DRM_kernel_mode_setting](https://wiki.archlinux.org/title/NVIDIA#DRM_kernel_mode_setting)
|
|
|
|
_\* Note_: If your GPU is listed as supported by the `nvidia-open-dkms` driver,
|
|
go with that one instead.
|
|
|
|
Following the wrapping instructions found at
|
|
[The Quick Start Page](https://github.com/hyprwm/Hyprland/wiki/Quick-start#wrapping-the-launcher-recommended),
|
|
wrap the launcher and additionally export these:
|
|
|
|
```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
|
|
```
|
|
|
|
Install `qt5-wayland`, `qt5ct` and `libva`. Additionally
|
|
`nvidia-vaapi-driver-git` (AUR) to fix crashes in some Electron-based
|
|
applications, such as Unity Hub.
|
|
|
|
Reboot your computer
|
|
|
|
Launch Hyprland with the wrapper.
|
|
|
|
It _should_ work now.
|
|
|
|
### Fixing random flickering
|
|
|
|
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.
