Can't get screensharing to work.. tried every step of the Thoubleshooting Checklist

[supersourix]

Hello,
First, thanks for your work. It allowed me to step into the hyprland world quickly.
However, I encounter only one issue, and it's sceeensharing.

I've gone through hours of troubleshooting in the hyprland docs and the wlr docs wich hyprland suggested (like the Screen sharing on Hyprland or the "It doesn't work" Troubleshooting Checklist) but with no luck, everything mentioned by them is working already apart from one thing which looks odd and might be the cause of the problem:

This is the output of this command:
systemctl --user status xdg-desktop-portal

Lots of errors here, might be related I guess ?
Thank you for your help

Hello, Interesting issue, let's start with the basics. Do you have "xdg-desktop-portal-hyprland" installed? also check your "hyprland.conf" and make sure you have a call to execute the "xdg-portal-hyprland" script. Confirm that script is executable as well. If all of that looks good do a "yay -Q | grep xdg" and post the results

I am also having the same issue.

The output of systemctl --user status xdg-desktop-portal

xdg-desktop-portal-hyprland is installed.

In hyprland.conf, "xdg-portal-hyprland" is present.

whats the status of
systemctl --user status xdg-desktop-portal-hyprland

Also is qt6-wayland and qt5-wayland packages installed?

Yes, qt6-wayland and qt5-wayland packages are both installed.

[SolDoesTech]

in hyprland.conf remove the comment from
exec-once=dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP
then logout and back in.
If that doesnt work can you try this and give me the output
systemctl --user status pipewire wireplumber

[Shubham-550]

exec-once=dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP
I tried this but same result.

5. Does the xdp service know your wayland socket?

❯ env | grep '^WAYLAND_DISPLAY='
WAYLAND_DISPLAY=wayland-1

❯ < "/proc/$(pidof xdg-desktop-portal)/environ" tr '\0' '\n' | grep '^WAYLAND_DISPLAY='
WAYLAND_DISPLAY=wayland-1

6. Does the xdp service know what your compositor is?

❯ < "/proc/$(pidof xdg-desktop-portal)/environ" tr '\0' '\n' | grep '^XDG_CURRENT_DESKTOP='
XDG_CURRENT_DESKTOP=Hyprland

7. Does the screencast starts, but the recording stays black or receives no image?

I run pw-dump from the link but I did not get an output in the terminal for that.

Please post your hyprland.conf, thank you.

[Shubham-550]

hyprland-config.txt

[supersourix]

On my end it looks like this:
✔️ xdg-desktop-portal-hyprland is installed

✔️ hyperland.conf is there and executable with correct permissions and I have a call to it in hyprland.conf

📓 Output of yay -Q | grep xdg
xdg-desktop-portal 1.16.0-1
xdg-desktop-portal-hyprland 0.3.1-1
xdg-utils 1.1.3+25+g8ae0263-1

✔️ systemctl --user status xdg-desktop-portal-hyprland is active and running

✔️ qt6-wayland and qt5-wayland packages are installed

📓 Output of systemctl --user status pipewire wireplumber both are active and running

Thank you again !

[Shubham-550]

Why is pipewire.service showing disabled?

❯ systemctl --user status pipewire
● pipewire.service - PipeWire Multimedia Service
Loaded: loaded (/usr/lib/systemd/user/pipewire.service; disabled; preset: enabled)
Active: active (running) since Sat 2023-04-29 22:23:21 IST; 2min 10s ago

And, why is xdg-desktop-portal inactive (dead)? How to make it active?

❯ systemctl --user status xdg-desktop-portal
○ xdg-desktop-portal.service - Portal service
Loaded: loaded (/usr/lib/systemd/user/xdg-desktop-portal.service; static)
Active: inactive (dead)

Thank you

[Shubham-550]

Solved:
I installed wlrobs-hg plugin. Add Source -> Wayland output(dmabuf).

yay -S wlrobs-hg

If I add Source -> Wayland output(scpy), obs crash.

Before posting here, I installed the plungin but added scpy source which crashed the obs. Then I uninstalled it.

Thank you Sol for your help.
