Screen sharing in Chromium failing #255

Open jalelegenda opened 1 year ago

jalelegenda commented 1 year ago

OS: Void Linux kernel: 6.0.15_1 WM: sway xdg portal version: 0.6.0

Getting error in Chromium when trying to share screen:

[19442:19442:0116/185100.491249:ERROR:screen_capture_portal_interface.cc(28)] Failed to get a proxy for the portal: Unknown or unsupported transport “disabled” for address “disabled:”
[19442:19442:0116/185100.491278:ERROR:base_capturer_pipewire.cc(77)] ScreenCastPortal failed: 3

rtkit and libpipewire0.2 installed. xdg-desktop-portal* daemons running. flag enabled in Chromium: enable-webrtc-pipewire-capturer Everything set as is explained over at https://wiki.archlinux.org/title/PipeWire#xdg-desktop-portal-wlr (XDG_CURRENT_DESKTOP and WAYLAND_DISPLAY) Screen sharing works on firefox and OBS, only Chromium seems to be failing. Please help me, thank you.

Which version of chromium are you using? If obs and firefox are working this might be related to a specific libwebrtc version

Yeah, hate to be that guy, but after reading the troubleshooting checklist, I fixed my issue. The problem was Chromium was not able to find the dbus bus or socket whatever. For anyone viewing this: I am using greetd login manager which runs a shell script which sets most of the necessary wayland related variables and runs sway. The issue was the script would execute sway directly instead of executing it as a dbus session. I replaced sway $@ with dbus-run-session sway $@. It still would not work. After I added exec dbus-update-activation-environment DISPLAY I3SOCK SWAYSOCK WAYLAND_DISPLAY XDG_CURRENT_DESKTOP=$nameofcompositor to my sway config file like it says in the troubleshooting checklist, the issue was fixed. You can close the issue, thanks :)
