Hi,
I’m on nixos (unstable) but this has already been bugging me for a while with previous releases.
It’s a hyprland config and I’m using firefox. When I’m clicking on “Show in folder” in the Downloads list (or alternatively in VSCode I right click a file and click “Open Containing Folder”) nothing happens…
That is,… I get some dbus messages with dbus-monitor, which I don’t fully understand however:

so it seems to do send request but I don’t understand why it is not fulfilled.
I have found:
and tried the various proposed desktop portal configs, but to no avail 
The workaround in the second post does indeed work, but I could only get it to work with dolphin (I would much rather like to use thunar however).
Also dolphin opens twice in this case?! (I rebooted to make sure that no services are running astray)
Proposed workaround from second reddit thread
systemd.user.services.plasma-dolphin = {
unitConfig = {
Description = "Dolphin file manager";
PartOf = [ "graphical-session.target" ];
};
path = [ "/run/current-system/sw" ];
environment = {
# don't add this if you are not wayland
QT_QPA_PLATFORM = "wayland";
};
serviceConfig = {
Type = "dbus";
BusName = "org.freedesktop.FileManager1";
ExecStart = "${pkgs.dolphin}/bin/dolphin";
};
};
Current (related) config
xdg.portal = {
enable = true;
xdgOpenUsePortal = true;
config.common.default = [
"gtk"
"hyprland"
];
# systemctl --user status xdg-desktop-portal-hyprland.service
extraPortals = [
pkgs.xdg-desktop-portal-gtk
pkgs.xdg-desktop-portal-hyprland
];
};
I’m just wondering, whether this is the correct workaround? Or should this work out of the box? Or how one could modify the service to work with thunar? Or maybe why dolphin opens twice with the proposed workaround?
Thanks!
