Project ID: 13960


ddcutil is a Linux utility for managing monitor settings, such as brightness, color levels, and input source. Generally speaking, any settings that can be displayed or changed by pressing buttons on the monitor can be modified by ddcutil.

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 support for monitors (such as Eizo ColorEdge displays) that implement MCCS using a USB connection.

Packaging Notes

COPR project ddcutil contans 2 COPR packages, ddcutil and ddcui. COPR package ddcutil contains the command line and shared library versions of ddcutil. It produces RPM packages ddcutil, libddcutilN and libddcutil-devel. COPR package ddcui builds a GUI interfeace for ddcutil. It produces RPM package ddcui. Note that COPR package ddcui was previously in a separate project ddcui. Unlike other build systems, this separation is unnecessary in COPR.
