Job for auto-xflux.service failed because the control process exited with error code.

For some reason the auto-xflux.service unit is not starting. When I run sudo systemctl start auto-xflux I receive:

Job for auto-xflux.service failed because the control process exited with error code.
See "systemctl status auto-xflux.service" and "journalctl -xe" for details.

Here is the status:

$ systemctl status auto-xflux.service

And here is what I have for the unit file:

$ cat auto-xflux.service
[Unit]
Description=Inputless xflux daemon that geocodes based on your external IP address
After=network.target display-manager.service

[Service]
Type=forking
ExecStart=/usr/bin/auto-xflux
Restart=always
Environment=DISPLAY=:0

[Install]
WantedBy=graphical.target

The packaged service unit file doesn't have the Environment line that you've included. The environment should already have the DISPLAY defined in advance of starting this unit.

To differentiate issues related to systemd vs. (auto-)xflux itself, execute /usr/bin/auto-xflux on its own. Running that has helped me pinpoint issues while developing this little package.

Thanks for getting back to me.

I ran auto-xflux by itself which revealved:

Sorry, we only support 8 and 10-bit displays right now.

I don't really know what it means, though.
