Chromium does not show file dialogs under Sway

gesperon commented 10 months ago

Describe the bug

Chromium does not show file dialogs under sway. /run/current-system/sw/share/xdg-desktop-portal/portals/gtk.portal has:


[portal]
DBusName=org.freedesktop.impl.portal.desktop.gtk
Interfaces=org.freedesktop.impl.portal.FileChooser;org.freedesktop.impl.portal.Print;org.freedesktop.impl.portal.Notification;org.freedesktop.impl.portal.Inhibit;org.freedesktop.impl.portal.Access;org.freedesktop.impl.portal.Account;org.freedesktop.impl.portal.Email;org.freedesktop.impl.portal.DynamicLauncher;org.freedesktop.impl.portal.Lockdown;
UseIn=gnome

Steps To Reproduce

Steps to reproduce the behavior:

Have Gnome, Sway and Chromium installed (I am also running gdm and i3).
Login into a Sway session.
Launch Chromium and try to "Save as" an image or page. Or try to upload a file somewhere.
The file dialog won't show up.

Expected behavior

For a file dialog to show up.

Additional context

I temporally fixed this behavior on my local PC forcing UseIn=gnome;sway:

nixpkgs.overlays = [ (self: super: {
  xdg-desktop-portal-gtk = super.xdg-desktop-portal-gtk.overrideAttrs {
    postInstall = ''
      sed -i 's/UseIn=gnome/UseIn=gnome;sway/' $out/share/xdg-desktop-portal/portals/gtk.portal
    '';
  };
} ) ];

but this is really ugly and dirty.

are you using ozone wayland?

@eclairevoyant

Do you mean the steps in https://nixos.wiki/wiki/Chromium ? under "Enabling native Wayland support" ? if so yes. I have trying both the environment variable and passing the arguments to chromium to no avail.

eclairevoyant commented 10 months ago

I would suggest trying without ozone wayland, as it's known to have some issues.

gesperon commented 10 months ago

Good to know. I have it disabled, so with or without it does not make a difference at least for the file dialogs.

I had the same problem with element-desktop and other apps, also with Gnome installed but not used. https://nixos.wiki/wiki/Sway#Using_NixOS suggests some workarounds for gtk applications. In my case, setting wrapperFeatures.gtk = true seems to be enough.

  programs.sway = {
    enable = true;
    wrapperFeatures.gtk = true;
  };

gesperon commented 10 months ago

wrapperFeatures.gtk = true; does not fix the issue for me. Do you have xdg.portal.extraPortals = [ pkgs.xdg-desktop-portal-gtk ] ; ?

philpax commented 1 month ago

I used your overlays workaround to solve this issue for myself. Thank you for putting it forward!

I can confirm that having wrapperFeatures.gtk = true and extraPortals = [ pkgs.xdg-desktop-portal-gtk ] does not resolve this by default.
