## HiDPI XWayland
|
||||
|
||||
XWayland currently looks pixelated/blurry on HiDPI screens, due to Xorg's
|
||||
inability to scale.
|
||||
There are attempts to add a standard scaling mechanism, such as
|
||||
[MR 733](https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/733).
|
||||
XWayland currently looks pixelated on HiDPI screens, due to Xorg's inability to
|
||||
scale.
|
||||
|
||||
You can use this MR's wlroots implementation in Hyprland by making a few changes.
|
||||
This problem is mitigated by the [`xwayland:force_zero_scaling`](../../Configuring/Variables/#xwayland)
|
||||
option, which forces XWayland windows not to be scaled.
|
||||
|
||||
{{< hint >}}
|
||||
The following instructions assume you know how to patch programs, either
|
||||
manually or using your favourite package manager.
|
||||
This will get rid of the pixelated look, but will not scale applications
|
||||
properly. To do this, each toolkit has its own mechanism.
|
||||
|
||||
See instructions for [manual patching](https://www.howtogeek.com/415442/how-to-apply-a-patch-to-a-file-and-create-patches-in-linux/)
|
||||
and [Pacman patching](https://wiki.archlinux.org/title/Patching_packages).

1. Have the latest `xwayland` package patched with at least
|
||||
[the HiDPI patch](https://github.com/hyprwm/Hyprland/blob/main/nix/patches/xwayland-hidpi.patch)
|
||||
(based on the MR's implementation, but updated).
|
||||
# unscale XWayland
|
||||
xwayland {
|
||||
force_zero_scaling = true
|
||||
}
|
||||
|
||||
2. Make sure you have the required Hyprland `wlroots`, patched with
|
||||
[the HiDPI xwayland patch](https://github.com/hyprwm/Hyprland/blob/main/nix/patches/wlroots-hidpi.patch)
|
||||
and [this commit](https://gitlab.freedesktop.org/wlroots/wlroots/-/commit/18595000f3a21502fd60bf213122859cc348f9af)
|

**reverted**. This is important, as not reverting it will make opening
|

XWayland programs crash Hyprland.

env = GDK_SCALE,2

The GDK_SCALE variable won't conflict with Wayland-native GTK programs.

### XWayland HiDPI
|
||||
|
||||
The `hyprland-hidpi` Nix package includes a patched wlroots that can render
|
||||
HiDPI XWayland windows.
|
||||
|
||||
In order to enable HiDPI when using the NixOS or Home Manager modules, you can
|
||||
set `programs.hyprland.xwayland.hidpi = true`, or
|
||||
`wayland.windowManager.hyprland.xwayland.hidpi = true`, respectively.
|
||||
|
||||
Now that the required package to achieve HiDPI is installed, an XWayland
|
||||
instruction is needed to set the scale:
|
||||
|
||||
```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 set different environment variables to make the specific toolkits
|
||||
render at the proper scaling. For example, add this to your `hyprland.conf`:
|
||||
|
||||
```ini
|
||||
env = GDK_SCALE,2
|
||||
env = XCURSOR_SIZE,48
|
||||
```
|
||||
|
||||
{{< hint >}}
|
||||
The `GDK_SCALE` environment variable won't conflict with Wayland-native GTK programs.

||||
