error - Could not create dbus interface

[taylon]

Clight version the issue has been seen with:

4.9-8069945

Used distribution:

Artix

When I run clight I get the following errors (full verbose log is attached):

Could not create dbus interface 'org.clight.clight.Conf.Backlight': Invalid argument
Could not create dbus interface 'org.clight.clight.Conf.Sensor': Invalid argument
Could not create dbus interface 'org.clight.clight.Conf.MonitorOverride': Invalid argument
Could not create dbus interface 'org.clight.clight.Conf.Inhibit': Invalid argument
Could not create dbus interface 'org.clight.clight.Conf.Dpms': Invalid argument
Could not create dbus interface 'org.clight.clight.Conf.Daytime': Invalid argument
Keyboard backlight calibration supported.
Could not create dbus interface 'org.clight.clight.Conf.Kbd': Invalid argument
BUS: Failed to connect to user bus
Could not create dbus interface 'org.clight.clight.Conf.Screen': Invalid argument
Could not create dbus interface 'org.clight.clight.Conf.Gamma': Invalid argument
Could not create org.clight.clight dbus interface: Channel number out of range
Failed to init. Killing module.
Could not create dbus interface 'org.clight.clight.Conf.Dimmer': Invalid argument

clightd is running but aparrently no module is loaded and so nothing happens.

If I run a commang like busctl --user call org.clight.clight /org/clight/clight org.clight.clight IncBl d 0.1 I get Failed to connect to bus: No such file or directory.

Not sure if it is relevant but I'm running with openrc (so no systemd). I also have a pretty minimal Artix install in general so I might be missing something important installed in the system.

Hi! Thanks for opening this issue! It seems like your session is not launching dbus; you shoud be able to run one using: https://linux.die.net/man/1/dbus-launch

hm... looks like it is running:

busctl list

any other ideas? or am I looking at the wrong thing?

Yep, i am talking about the user dbus session; can you try: busctl --user status?

[taylon]

That was it! I added dbus-launch clight & to my xinitrc and it worked great. Thank you very much :)
