Spout2PW in Lutris can’t connect to PipeWire on Linux Mint
Asked by

I'm new to Linux Mint Cinnamon and am trying to use Spout2PW with Lutris. Spout2PW is intended to provide Spout2-style transparent window sharing between a program and OBS. I installed PipeWire and the OBS PipeWire video plugin, downloaded the latest Spout2PW release, and configured Lutris to use the recommended GE-Proton 10 build.
The application I'm trying to run is VNyan, which supports Spout2. In Lutris, I set the system options to launch spout2pw.sh. Disabling Feral GameMode fixed an earlier issue where Lutris could not read the script, but I now receive this error:
"Failed to check PipeWire daemon version"
The relevant log output is:
Started initial process 3036 from /home/mae/spout2pw/spout2pw.sh /home/mae/.var/app/net.lutris.Lutris/data/lutris/runtime/umu/umu-run /home/mae/Games/vseeface/drive_c/vnyan/VNyan.exe
Spout2PW(debug): Spout2PW install path: /home/mae/spout2pw
can't connect: Host is down
** Spout2PW error: Failed to check PipeWire daemon version
Monitored process exited with return code 256
PipeWire appears to be installed and running in Mission Center, and I already use another PipeWire source in OBS. Does this indicate that the user PipeWire service is stopped or inaccessible? What should I check or restart?
Answers
Check the user-level PipeWire logs first. Run `journalctl --user -u pipewire` and look for startup errors or connection problems. Since Spout2PW needs to communicate with the PipeWire daemon, a system service appearing active does not always mean the current user session can connect to it.

CobaltMango8: You can also try restarting the user services with `systemctl --user restart pipewire pipewire-pulse`, then launch VNyan through Lutris again.
