Specify ALL to debug all signals or specify signal using it’s full name. d-signal If -d signal or -d all is specified, specify the signal to debug using this option. You can use this option multiple times if you want debugging output of more than one subsystem (e.g. There are several subsystems of darktable and debugging of each of them can be activated separately.

The darktable binary starts darktable with its GUI and full functionality.
