xdg-portal-kde -- KDE XDG Desktop Portal backend
Layer Properties
| Property | Value |
|----------|-------|
| Dependencies | dbus, kwin, pipewire |
| Install files | layer.yml, tasks:, portals.conf |
Environment Variables
| Variable | Value |
|----------|-------|
| XDG_CURRENT_DESKTOP | KDE |
Packages
xdg-desktop-portal(RPM) -- Portal daemonxdg-desktop-portal-kde(RPM) -- KDE portal backend (ScreenCast, RemoteDesktop, FileChooser)
Portal Configuration
portals.conf (installed to ~/.config/xdg-desktop-portal/portals.conf):
[preferred]
default=kde
org.freedesktop.impl.portal.ScreenCast=kde
org.freedesktop.impl.portal.RemoteDesktop=kde
Routes ScreenCast and RemoteDesktop requests to the KDE backend, which supports both PipeWire screen capture and libei input injection.
Portal Capabilities
The KDE portal backend provides:
- ScreenCast -- PipeWire-based screen capture via
zkde_screencast_unstable_v1 - RemoteDesktop -- Input injection via libei/EIS (
ConnectToEISmethod) - FileChooser, Screenshot, Notification, GlobalShortcuts, InputCapture, Clipboard
Known Limitation
The zkde_screencast_unstable_v1 Wayland protocol is not exposed by KWin's --virtual backend (as of KDE 6.6.3). Portal ScreenCast/RemoteDesktop sessions fail with response code 2 in headless mode.
