Hello,

i would like to use disman with sway. But after trying to start with exec dismanctl -o in the config or dismanctl -o from the command line, i received the following error:

disman: Failed to request backend: "org.freedesktop.DBus.Error.Spawn.ChildSignaled" : "Process org.kwinft.disman received signal 6"
disman.ctl: Received initial config has error.
disman.ctl: Invalid config.

journalctl gave the following ouput:

I tried to clear ~/.local/share/disman, but without success.
Disman works without a problem in a Plasma-Wayland-session.

I hope the provided information are enough.

Best regards and many thanks in advance

Thanks for your report. Please add some lines to a config file for more debug output as explained here.

I don't know if i am just stupid, but creating ~/.config/QtProject/qtlogging.ini and adding the described line didn't enabled anymore debug output for me.
journalctl produced the same output as already posted, and it didn't produced any additional log when running dismanctl -o.

I will try a fresh install tomorrow, to check if any packages conflict with disman.

However, /usr/lib/libexec/disman_backend_launcher doesn't get installed by the AUR-Package, and therefore can not be started as mentioned in the CONTRIBUTING.md

According to the PKGBUILD it overrides the CMAKE_INSTALL_LIBEXECDIR variable with lib. So you might find the launcher in a different directory.

Starting disman_backend_launcher solved the problem.
So it seems like dismanctl can't start disman_backend_launcher, if the location of disman_backend_launcher has changed (e.g. in the case of the Arch-Linux package).

Hmm, the backend should start automatically via D-Bus activation even if it's installed to a different directory I would say.

The issue might actually be that the installed service file fills in a different variable CMAKE_INSTALL_FULL_LIBEXECDIR and not CMAKE_INSTALL_LIBEXECDIR. Not sure if the variable from the PKGBUILD script does override this one too.
