In package-manager culture it fills the practical gap between desktop display settings panels and scriptable monitor control. ### Project history The project was created and maintained by Sanford Rockowitz, and its official documentation says the use case that inspired development was color profile management: saving monitor color settings during calibration and restoring them when the profile is applied. The public GitHub release history goes back to 0.5.0 in 2016 and the project has continued through the 2.x series with both the ddcutil CLI and libddcutil shared library. ### Adoption history ddcutil became a distribution-facing tool because Linux desktops and automation scripts needed a standard way to address monitor controls exposed through /dev/i2c devices. Its documentation maintains package-status material and maintainer notes, and recent release notes call out KDE PowerDevil integration work around display connection handling and transient I2C permission loss. ### How it is used Typical package usage is small but powerful: detect attached displays, query VCP capabilities, get and set values such as brightness or input source, and integrate those commands into desktop power, color-management, or hotkey workflows. The same project also exposes libddcutil for applications that need monitor control without shelling out. ### Why package nerds care ddcutil matters to package nerds because it wraps a hardware-adjacent protocol in a scriptable Unix tool while still needing udev, kernel module, I2C permission, and monitor quirk handling. It is the sort of package where a formula is only half the story; post-install configuration and distro integration determine whether it works. ### Timeline - 2015: Public GitHub repository created. - 2016: Release 0.5.0 published. - 2025: Release 2.2.0 published in the modern libddcutil series. - 2026: Release 2.2.7 published with fixes relevant to KDE PowerDevil and display connection handling. ### Related projects - ddcui provides a Qt graphical interface built around ddcutil. - KDE PowerDevil is a desktop power-management consumer called out by the ddcutil release notes. - The Monitor Control Command Set and DDC/CI standards define much of the monitor-control surface ddcutil exposes. ### Sources - - - - ## Security Notes No matching local secret-handling manifest was found for ddcutil. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: $XDG_CONFIG_HOME/ddcutil/ddcutilrc, ~/.config/ddcutil/ddcutilrc ## Source Database Details -
