Failed to get application states

[thiagovespa]

When I start the xdg-desktop-portal:

systemctl --user start xdg-desktop-portal{,-gtk}

I got this message:

xdg-desktop-por[3030]: Failed to get application states: GDBus.Error:org.freedesktop.portal.Error.Failed: Could not get window list

I'm using xfce4 but I have gtk applications.

Package versions: xdg-desktop-portal 1.14.6 xfce-desktop 4.16.0 gtk 4.6.7

Do you have xdg-desktop-portal-gtk installed?

XFCE does not provide any implementation for window listing, and xdg-desktop-portal-gtk does not have XFCE-specific knowledge to do that. The path forward is for XFCE developers to provide xdg-desktop-portal-xfce which would use XFCE-specific APIs to provide that.
