# Foreword
|
|
|
|
There is no _official_ Hyprland support for Nvidia hardware. However, you might
|
|
make it work properly following this page.
|
|
|
|
You can choose between the proprietary
|
|
[Nvidia drivers](https://wiki.archlinux.org/title/NVIDIA) or the open source
|
|
[Nouveau driver](https://wiki.archlinux.org/title/Nouveau). Under the
|
|
proprietary Nvidia drivers category, there are 3 of them: the current driver
|
|
named 'nvidia' (or 'nvidia-dkms' to use with custom linux kernels) which is
|
|
under active development, the legacy drivers 'nvidia-3xxxx' for older cards
|
|
which Nvidia no longer actively supports, and the 'nvidia-open' driver which is
|
|
currently an alpha stage attempt to open source a part of their close source
|
|
driver for newer cards.
|
|
|
|
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.
|
|
|
|
Below are some tips to try to make the proprietary Nvidia driver work with
|
|
Hyprland properly:
|
|
|
|
## 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](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
|
|
`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](https://wiki.archlinux.org/title/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:
|
|

|
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:
|
|
|
|
```sh
|
|
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
|
|
```
|
|
|
|
{{< callout >}}
|
|
|
|
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 random flickering, (nuclear method)
|
|
|
|
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:
|
|
|
|
```sh
|
|
options nvidia NVreg_RegistryDwords="PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"
|
|
```
|
|
|
|
Reboot your computer and it should be working.
|
|
|
|
If it does not, try:
|
|
|
|
- lowering your monitors' refresh rate, as this can stop the flickering
|
|
altogether
|
|
- installing the 535xx versions of the drivers, as later (545, 550) can cause
|
|
flickering with XWayland
|
|
- these are available for arch via
|
|
[the AUR here](https://aur.archlinux.org/packages?O=0&K=535xx)
|
|
- using the [Nouveau driver](https://wiki.archlinux.org/title/Nouveau) as
|
|
mentioned above
|
|
|
|
## Fixing suspend/wakeup issues
|
|
|
|
Enable the services `nvidia-suspend.service`, `nvidia-hibernate.service` and
|
|
`nvidia-resume.service`, they will be started by systemd when needed.
|
|
|
|
Add `nvidia.NVreg_PreserveVideoMemoryAllocations=1` to your kernel parameters if
|
|
you don't have it already.
|
|
|
|
{{< callout >}}
|
|
|
|
Suspend functions are currently broken on `nvidia-open-dkms`
|
|
[due to a bug](https://github.com/NVIDIA/open-gpu-kernel-modules/issues/472), so
|
|
make sure you're on `nvidia-dkms`.
|
|
|
|
{{< /callout >}}
|
|
|
|
For Nix users, the equivalent of the above is
|
|
|
|
```nix
|
|
# configuration.nix
|
|
|
|
boot.kernelParams = [ "nvidia.NVreg_PreserveVideoMemoryAllocations=1" ];
|
|
|
|
hardware.nvidia.powerManagement.enable = true;
|
|
|
|
# Making sure to use the proprietary drivers until the issue above is fixed upstream
|
|
hardware.nvidia.open = false;
|
|
```
