What you see is just the beginnings of the project. I need a small library of functions that will allow me to collect data on the status of the driver, status of the USB connection, and status of the display providers. I also need to be able to automatically turn on the driver, set the output sources, and preferably, turn on and position my monitors based on some sort of preset file. This rc.d instruction set isn't final. My aim is to have USB detection handled in the RC.d first that will be the primary condition to control whether the display link driver is even allowed to run, then drive my displaylink libraries after the fact. I am just trying to get the monitor setup automated first, because that is what is important at the moment. I can easily create a thread that runs on a while loop that runs on a lsusb | grep displaylink condition. It seems that debian and CentOS both report my dock as a Displaylink device, so this may actually be a plausible condition to design. Just keep watching
If you know how to adjust monitor size and position with CLI commands, this will be a HUGE help.
Edit: emphasis on additional monitor setup using cli or config files.
