An XDG Desktop Portal (later called XDP) is a program that lets other
applications communicate swiftly with the compositor through D-Bus.
It's used for stuff like e.g. opening file pickers, screen sharing.
On Wayland, it also requires an implementation. For Hyprland,
you'd usually use `xdg-desktop-portal-wlr` (later called XDPW)
Unfortunately, due to various reasons the -wlr portal is inferior
to the KDE or Gnome ones.
In order to bridge the gap, Hyprland has its own fork of XDPW that
has more features, called [xdg-desktop-portal-hyprland](https://github.com/hyprwm/xdg-desktop-portal-hyprland).
(later called XDPH)
{{< hint type=important >}}
You don't **need** XDPH. Hyprland will work with XDPW, but XDPH has more features, like e.g.

window sharing.

XDPH will work on other wlroots-based compositors, although limited to the XDPW features (other
will be disabled)

```
## Apply necessary useflags

btw those are the useflags that I have tested, you could also test others.

{{< hint type=tip >}}
XDPH doesn't implement a file picker. For that, I recommend installing `xdg-desktop-portal-gtk` alongside XDPH.

## Usage
Should start automatically.
The most basic way of telling everything is OK is by trying to screenshare anything, or
open OBS and select pipewire source. If XDPH is running, a qt menu will pop up asking you
what to share.
If it doesn't, and you get e.g. slurp, then XDPW is launching. In that case, try removing XDPW.
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:
```sh
#!/bin/bash
sleep 1
killall -e xdg-desktop-portal-hyprland
killall -e xdg-desktop-portal-wlr
2022-12-03 23:52:10 +01:00
killall xdg-desktop-portal
2023-02-08 11:18:09 +01:00
/usr/lib/xdg-desktop-portal-hyprland &
2022-12-03 23:52:10 +01:00
sleep 2
/usr/lib/xdg-desktop-portal &
```
2022-12-05 02:01:55 +01:00
adjust the paths if incorrect.

## 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 most likely you are missing `qt6-wayland` and/or `qt5-wayland`.
