# Hyprland crashes on startup after updating packages (Nvidia)

Most likely mkinitcpio wasn't run to regenerate initramfs after update.

Try running `sudo mkinitcpio -P` and reboot.

If Hyprland starts properly after doing so, make sure you have followed [this step](../../Nvidia/#kernel-parameters), specifically the bit about adding a [pacman hook](https://wiki.archlinux.org/title/NVIDIA#pacman_hook), and mkinitcpio will be run any time pacman updates your drivers.

# Foreword

There is no _official_ Hyprland support for Nvidia hardware. However, you might make it work properly following this page.
There is no _official_ Hyprland support for Nvidia hardware. However, you might make it work properly following this page.

## Drivers
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
{{< hint type=warning >}}
All of the tips are intended to work with `nvidia`, `nvidia-open` or `nvidia-dkms` and do not work with the legacy or Nouveau drivers.

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.

add the [pacman hook](https://wiki.archlinux.org/title/NVIDIA#pacman_hook) to ensure mkinitcpio is regenerated when nvidia drivers are updated (arch only)

{{< hint >}}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.

## Additional packages
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.
After completing all of the above, Hyprland should _at least_ be able to start.
