There is no _official_ Hyprland support for Nvidia hardware. However, many people

have had success with the instructions on this page.

|
||||
|
||||
You may want to use the proprietary Nvidia drivers in some cases, for example:
|
||||
if you have a new Nvidia GPU model, if you want more performance, if you want to
|
||||
play video games, if you need a wider feature set (for example, better power
|
||||
consumption on recent GPUs), etc. However, keep in mind that if the proprietary
|
||||
Nvidia drivers do not work properly on your computer, the Nouveau driver might
|
||||
work fine while not having as much features or performance. For
|
||||
[older cards](https://wiki.archlinux.org/title/NVIDIA#Unsupported_drivers), in
|
||||
order to use Hyprland, you will probably need to use the Nouveau driver which
|
||||
actively supports them.

If your card is supported by the proprietary nvidia drivers, there is a very
|

high chance that you will most likely want to use those. Benefits include but

are not limited to:
|
||||
|
||||
Below are some tips to try to make the proprietary Nvidia driver work with
|

Hyprland properly:
|

- (Much) better gaming performance
|
||||
- Better power management on recent GPUs

## How to get Hyprland to possibly work on Nvidia
|
||||
However, keep in mind that if the proprietary Nvidia drivers do not work
|
||||
properly on your computer, the Nouveau driver might work fine. This will
|
||||
most likely be the case for
|
||||
[older cards](https://wiki.archlinux.org/title/NVIDIA#Unsupported_drivers)
|
||||
|
||||
## How to get Hyprland to possibly run on Nvidia (Proprietary)
|
||||
|
||||
Install the correct headers package for your current kernel. For the example of
|
||||
the `linux-zen` kernel on Arch Linux, this package would be `linux-zen-headers`.
|
||||
|
||||
Install the required nvidia packages. For most cases, this would be `nvidia-dkms`
|
||||
(or `nvidia-open-dkms` for the open source ones),
|
||||
and `nvidia-utils`. If you'd like to game via Wine or even natively, it would be
|
||||
in your best interest to also install `lib32-nvidia-utils`.
|
||||
|
||||
{{< callout >}}
|
||||
|
||||
Even if your GPU is listed as supported by the `nvidia-open-dkms` driver, at this
|
||||
point in time, it is still not up to feature parity with the proprietary drivers.
|
||||
One issue with the open drivers is that it could cause problems with suspend in
|
||||
general, let that be closing the lid on your laptop or by manually triggering one.
|
||||
Overall, you'd be better off with `nvidia-dkms` right now, but Hyprland should work
|
||||
similarly between the two.
|
||||
|
||||
{{< /callout >}}
|
||||
|
||||
Next up, you need to enable modeset for nvidia, this can be done via editing
|
||||
the kernel paramaters for your bootloader.
|
||||
|
||||
Install the `nvidia-dkms` driver and add it to your initramfs & kernel
|
||||
parameters.\
|
||||
For people using [systemd-boot](https://wiki.archlinux.org/title/systemd-boot)
|
||||
you can do this adding `nvidia_drm.modeset=1` to the end of
|
||||
`/boot/loader/entries/arch.conf`. For people using
|
||||
[grub](https://wiki.archlinux.org/title/GRUB) you can do this by adding
|
||||
you can do this by adding `nvidia_drm.modeset=1` to the end of
|
||||
`/boot/loader/entries/arch.conf`.
|
||||
|
||||
For people using
|
||||
[GRUB](https://wiki.archlinux.org/title/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
|
||||
`/etc/default/grub`, then running `sudo grub-mkconfig -o /boot/grub/grub.cfg`.
|
||||
|
||||
For others check out
|
||||
[kernel parameters](https://wiki.archlinux.org/title/Kernel_parameters) and how
|
||||
to add `nvidia_drm.modeset=1` to your specific bootloader.
|
||||
|
||||
{{< callout >}}
|
||||
|
||||
There has been a lot of debate on which of `nvidia_drm` or `nvidia-drm`
|
||||
is correct for this kernel parameter. It has been confirmed that either
|
||||
of these will work.
|
||||
|
||||
{{< /callout >}}
|
||||
|
||||
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)
|
||||
For example, a clean `MODULES` line would now look like this:
|
||||
```sh
|
||||
MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)
|
||||
```
|
||||
|
||||
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`
|
||||
Now, run `sudo mkinitcpio -P`. This will regenerate the initcpios for all kernels
|
||||
currently installed on the system. If you see any errors here about missing
|
||||
nvidia modules, it is highly probable that you forgot to install the correct
|
||||
headers package. Make sure you install the headers package for your kernel and
|
||||
run this command again.

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.
|
||||
|
||||
{{< /callout >}}
|

|

Export these variables in your hyprland config:

env = WLR_NO_HARDWARE_CURSORS,1

|
||||
Lastly, you also need to install a few packages to get some apps
|
||||
to function natively with Wayland. Have a look at [the Master Tutorial](https://wiki.hyprland.org/Getting-Started/Master-Tutorial/#force-apps-to-use-wayland).

## Fixing random flickering, (nuclear method)
|
||||
## VA-API hardware video acceleration
|
||||
|
||||
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).
|
||||
We can achieve VA-API acceleration on Nvidia and Wayland with the help of the
|
||||
[nvidia-vaapi-driver](https://github.com/elFarto/nvidia-vaapi-driver). This may
|
||||
solve certain issues in Electron apps, and it will also allow for GPU decoding
|
||||
for videos on the web, with benefits including higher performance video playback
|
||||
and also higher power efficiency during video playback.
|
||||
|
||||
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.
|
||||
Its install instructions are available in the README, however, a quick guide will
|
||||
be given here:
|
||||
|
||||
- Install the package. On Arch, this is `libva-nvidia-driver` in the official
|
||||
repos.
|
||||
|
||||
- export this variable in your hyprland config:
|
||||
```sh
|
||||
env = NVD_BACKEND,direct
|
||||
```
|
||||
see [here](https://github.com/elFarto/nvidia-vaapi-driver?tab=readme-ov-file#upstream-regressions)
|
||||
for more information on this environment variable.
|
||||
|
||||
- Enable the services `nvidia-suspend.service`, `nvidia-hibernate.service` and
|
||||
`nvidia-resume.service`
|
||||
|
||||
- Add `nvidia.NVreg_PreserveVideoMemoryAllocations=1` to your kernel parameters if
|
||||
you don't have it already. This will solve issues with corrupted desktop / videos
|
||||
after waking.
|
||||
|
||||
- You can check the README to get it working for Firefox.
|
||||
|
||||
## Other issues to look out for
|
||||
|
||||
### Regarding environment variables
|
||||
|
||||
- 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, first try running them in Native Wayland (more details below).
|
||||
Otherwise, remove or comment the line
|
||||
`env = __GLX_VENDOR_LIBRARY_NAME,nvidia`.
|
||||
|
||||
### How to possibly get multi-monitor working with hybrid graphics
|
||||
|
||||
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.
|
||||
|
||||
### Fixing flickering in Electron / CEF apps
|
||||
|
||||
This flickering is likely caused by these apps running in XWayland.
|
||||
To fix the flickering, try running the apps with native Wayland instead.
|
||||
|
||||
For most Electron apps, you should be fine just adding this
|
||||
environment variable to your config:
|
||||
|
||||
```sh
|
||||
env = ELECTRON_OZONE_PLATFORM_HINT,auto
|
||||
```
|
||||
|
||||
This has been confirmed to work on Vesktop, VSCodium and Obsidian and will probably
|
||||
work on other Electron apps as well.
|
||||
|
||||
For other apps, including CEF apps, you will need to launch them with these flags:
|
||||
|
||||
```sh
|
||||
--enable-features=UseOzonePlatform --ozone-platform=wayland
|
||||
```
|
||||
|
||||
To do this easily for Spotify, Arch Linux has a `spotify-launcher` packages
|
||||
in their official repos. You should use that instead of the `spotify`
|
||||
package in the AUR. Then, enable the Wayland backend in
|
||||
`/etc/spotify-launcher.conf` by uncommenting this line:
|
||||
|
||||
```sh
|
||||
extra_arguments = ["--enable-features=UseOzonePlatform", "--ozone-platform=wayland"]
|
||||
```
|
||||
|
||||
Some CEF / Electron apps may also have a respective flags file in ~/.config.
|
||||
For example, for VSCodium, you can add the flags to `~/.config/codium-flags.conf`
|
||||
and for Obsidian, you can add the flags to `~/.config/obsidian/user-flags.conf`.
|
||||
|
||||
{{< callout >}}
|
||||
|
||||
On earlier Nvidia driver versions, including 535, you may have to also include
|
||||
the `--disable-gpu` and `--disable-gpu-sandbox` flags, but, as the names suggest,
|
||||
you will lose hardware acceleration for whichever app is run with these flags.
|
||||
|
||||
{{< /callout >}}
|
||||
|
||||
With NixOS, you can also try setting the `NIXOS_OZONE_WL` environment variable
|
||||
to `1`, which should automatically configure Electron / CEF apps to run with native
|
||||
Wayland for you.
|
||||
|
||||
While it is best to have as many things as possible running natively in
|
||||
wayland, the root cause of the flickering will likely be solved
|
||||
in the 555 series of nvidia driver updates.
|
||||
|
||||
### Fixing flickering in XWayland games specifically
|
||||
|
||||
The symptoms of this widespread issue include XWayland games flickering in
|
||||
a way which makes them unplayable. Repeated frames, random presenting of
|
||||
black frames, and overall weirdness. This is a result of a multitude of
|
||||
issues which will be solved soon via Nvidia driver updates, but for now
|
||||
you have a few possible fixes:
|
||||
|
||||
- Install xorg-xwayland-git (AUR). This git package includes this [PR](https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/967)
|
||||
which implements the "Explicit Sync" protocol.
|
||||
This will fix it in some, if not all cases. However if it doesn't,
|
||||
try the next solution. Once the 555 series of drivers are released, this
|
||||
should completely fix the issue.
|
||||
|
||||
- Install older nvidia drivers which do not exhibit this problem. The
|
||||
last ones which would work will be the 535xx series of drivers. These
|
||||
can be installed easily on Arch via [these AUR packages](https://aur.archlinux.org/packages?O=0&K=535xx)
|
||||
|
||||
More info about explicit sync is available
|
||||

|
||||
|
||||
### Fixing other random flickering (nuclear method)
|
||||
|
||||
Do note that this forces performance mode to be active, resulting in
|
||||
increased power-consumption (from 22W idle on an RTX 3070TI, to 74W).
