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)

{{< hint type=tip >}}
|
|
XDPH doesn't implement a file picker. For that, I recommend installing `xdg-desktop-portal-gtk` alongside XDPH.
|
|
{{< /hint >}}
|
|
|
|
## 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
|
|
killall xdg-desktop-portal
|
|
/usr/lib/xdg-desktop-portal-hyprland &
|
|
sleep 2
|
|
/usr/lib/xdg-desktop-portal &
|
|
```
|
|
adjust the paths if incorrect.
|
|
|
|
## Share picker doesn't use the system theme
|
|
|
|
Try one or both:
|
|
```sh
|
|
dbus-update-activation-environment --systemd --all
|
|
systemctl --user import-environment QT_QPA_PLATFORMTHEME
|
|
```
|
|
|
|
If it works, add it to your config in an `exec-once`.
|
|
|
|
## 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`.
