You can override the package through `.override` or `.overrideAttrs`. This is
|
||
|
|
easily achievable through NixOS or Home Manager.
|
||
|
|
|
||
|
|
## Package options
|
||
|
|
|
||
|
|
These are the default options that the Hyprland package is built with. These
|
||
|
|
can be changed by setting the appropriate option to `true`/`false`.
|
||
|
|
|
||
|
|
### Package
|
||
|
|
|
||
|
|
```nix
|
||
|
|
(inputs.hyprland.packages.${pkgs.default}.default.override {
|
||
|
|
enableXWayland = true;
|
||
|
|
hidpiXWayland = true;
|
||
|
|
nvidiaPatches = false;
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
### NixOS & HM modules
|
||
|
|
|
||
|
|
```nix
|
||
|
|
programs.hyprland = { # or wayland.windowManager.hyprland
|
||
|
|
enable = true;
|
||
|
|
xwayland = {
|
||
|
|
enable = true;
|
||
|
|
hidpi = true;
|
||
|
|
};
|
||
|
|
nvidiaPatches = false;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Options descriptions
|
||
|
|
|
||
|
|
### XWayland
|
||
|
|
|
||
|
|
XWayland is enabled by default in the Nix package. You can disable it either
|
||
|
|
in the package itself, or through the module options.
|
||
|
|
|
||
|
|
### XWayland HiDPI
|
||
|
|
|
||
|
|
By default, the Nix package includes a patched wlroots that can render HiDPI
|
||
|
|
XWayland windows.
|
||
|
|
|
||
|
|
In order to enable the functionality, you have to add:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
exec-once=xprop -root -f _XWAYLAND_GLOBAL_OUTPUT_SCALE 32c -set _XWAYLAND_GLOBAL_OUTPUT_SCALE 2
|
||
|
|
```
|
||
|
|
|
||
|
|
This will make XWayland programs look as if they were unscaled. To fix this, you
|
||
|
|
have to export different environment variables to make the specific toolkits
|
||
|
|
render at the proper scaling. For example
|
||
|
|
|
||
|
|
```sh
|
||
|
|
export GDK_SCALE=2
|
||
|
|
export XCURSOR_SIZE=48
|
||
|
|
```
|
||
|
|
|
||
|
|
{{< hint >}}
|
||
|
|
The GDK_SCALE variable won't conflict with wayland-native GTK programs.
|
||
|
|
{{< /hint >}}
|
||
|
|
|
||
|
|
Usually, there's no reason to disable this functionality, as it won't affect
|
||
|
|
people who don't have HiDPI screens.
|
||
|
|
|
||
|
|
If you _do_ insist on disabling it though (e.g. for adding your own patches
|
||
|
|
to wlroots), you can do so by either using the `hyprland-no-hidpi` package,
|
||
|
|
or by passing the `hidpiXWayland = false;` flag, the same way as
|
||
|
|
[disabling XWayland](#package)
|
||
|
|
|
||
|
|
### Nvidia Patches
|
||
|
|
|
||
|
|
Nvidia is notorious for not working by default with wlroots. That's why we
|
||
|
|
patch wlroots.
|
||
|
|
|
||
|
|
## Using Nix repl
|
||
|
|
|
||
|
|
If you're using Nix (and not NixOS or Home Manager) and you want to override,
|
||
|
|
you can do it like this
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ nix repl
|
||
|
|
nix-repl> :lf "github:hyprwm/Hyprland"
|
||
|
|
nix-repl> :bl outputs.packages.x86_64-linux.hyprland.override {nvidiaPatches = true;} # option = value
|
||
|
|
```
|
||
|
|
|
||
|
|
Then you can run Hyprland from the built path.
