An XDG Desktop Portal is a program that lets other applications communicate with the compositor through D-Bus.
A portal implements certain functionalities, such as opening file pickers or screen sharing.
xdg-desktop-portal-hyprland is Hyprland's xdg-desktop-portal implementation. It allows for screensharing, global shortcuts, etc.
{{< callout type="info" >}}
Throughout this document, xdg-desktop-portal-hyprland
will be referred to as
XDPH.
{{< /callout >}}
{{< callout >}}
XDPH doesn't implement a file picker. For that, it is recommended to install
xdg-desktop-portal-gtk
alongside XDPH.

Installing
{{< tabs items="Arch Linux,NixOS,Gentoo,Manual" >}}
{{< tab "Arch Linux" >}}
pacman -S xdg-desktop-portal-hyprland
or, for -git:
yay -S xdg-desktop-portal-hyprland-git
{{< /tab >}}
{{< tab "NixOS" >}}
On NixOS, XDPH is already enabled by the
NixOS module for Hyprland, through
programs.hyprland.enable = true;
.

Usage
XDPH is automatically started by D-Bus, once Hyprland starts.
To check if everything is OK is, try to screenshare anything, or opening OBS and select the PipeWire source. If XDPH is running, a Qt menu will pop up asking you what to share.
XDPH will work on other wlroots compositors, but features available only on Hyprland will not work (e.g. window sharing).
For a nuclear option, you can use this script and exec-once
it:
#!/usr/bin/env bash
sleep 1
killall -e xdg-desktop-portal-hyprland
killall xdg-desktop-portal
/usr/lib/xdg-desktop-portal-hyprland &
sleep 2
/usr/lib/xdg-desktop-portal &
Adjust the paths if they're incorrect.
Share picker doesn't use the system theme
Try one or both:
dbus-update-activation-environment --systemd --all
systemctl --user import-environment QT_QPA_PLATFORMTHEME
If it works, add it to your config in exec-once
.
Using the KDE file picker with XDPH
XDPH does not implement a file picker and uses the GTK one as a fallback by
default (see /usr/share/xdg-desktop-portal/hyprland-portals.conf
). If you want
to use the KDE file picker but let XDPH handle everything else, create a file
~/.config/xdg-desktop-portal/hyprland-portals.conf
with the following content:
[preferred]
default = hyprland;gtk
org.freedesktop.impl.portal.FileChooser = kde
You can read more about this in the xdg-desktop-portal documentation in the Arch Wiki. Note that some applications like Firefox may require additional configuration to use the KDE file picker.
Debugging
If you get long app launch times, or screensharing does not work, consult the logs.
systemctl --user status xdg-desktop-portal-hyprland
If you see a crash, it's likely you are missing either qt6-wayland
or
qt5-wayland
.
If the portal does not autostart, does not function when manually started, and does not produce any error logs, it's very likely your XDG env variables are messed up
Configuration
Example:
screencopy {
max_fps = 60
}
Config file ~/.config/hypr/xdph.conf
allows for these variables:
category screencopy
variable | description | type | default value |
---|---|---|---|
max_fps | Maximum fps of a screensharing session. 0 means no limit. | int | 120 |
allow_token_by_default | If enabled, will tick the "Allow restore token" box by default | bool | false |
