Summary
ddcutil primarily uses DDC/CI (Display Data Channel Command Interface) to communicate with monitors implementing MCCS (Monitor Control Command Set) over I2C. Normally, the video driver for the monitor exposes the I2C channel as devices named /dev/i2c-n. Alternatively, there is initial support for monitors (such as Apple displays) that implement MCCS using a USB connection.

- introspection
- Add support for GObject based introspection
- usb-monitor
- Adds support for monitors attached via USB.
- user-permissions
- Adds a udev rules to allow non-root users in the i2c group to access the /dev/i2c-* devices. If usb-monitor is selected, users will need to be added to the video group to access the USB monitor. Otherwise, only root will be able to use ddcutil.
