signal-desktop on wayland: black screen when screen sharing #251371

Closed teutat3s closed 10 months ago

teutat3s commented 1 year ago

Describe the bug

According to this upstream issue, Signal-Desktop now supports screen sharing on wayland. Using sway on nixos and the latest signal-desktop version on nixpkgs, 6.27.1, I can only share a black screen. Maybe there's a dependency missing for screen sharing to work?

Steps To Reproduce

Steps to reproduce the behavior:

  1. Start Signal-Desktop on Wayland (sway)
  2. Start a call
  3. Start screen sharing, select "share whole screen"
  4. Confirm only a black screen gets shared

Expected behavior

The whole screen should get shared.

Maybe these packages help: I still have the same problem though:

xdg-desktop-portal xdg-desktop-portal-gtk (not sure if this one is needed) xdg-desktop-portal-gnome

gabyx commented 10 months ago

I see the same issue under NixOs and sway (https://github.com/gabyx/dotfiles/blob/82b9b9a5a2ab8ae2cd8cc1db4218c91469b3f36f/nixos/modules/windowing.nix)

with the following enabled. Chrome with Google Meets works so far.

 xdg.portal = {
    enable = true;
    extraPortals = [pkgs.xdg-desktop-portal pkgs.xdg-desktop-portal-gtk ]
  };

Hopefully #267050 fixes this.
