DDCcontrol
DDCcontrol is free Linux software for changing monitor brightness, contrast, color levels and other settings through DDC/CI. It offers a GTK interface for graphical control and a command-line tool for terminals, scripts and automation. Communication uses Linux’s i2c-dev interface and /dev/i2c-* devices, which must be readable and writable before monitors can be configured. USB-connected DDC/CI displays are not supported yet. A monitor database is required for monitor-specific controls and proper operation. The ddccontrol-scanmonitor utility reads a connected display’s EDID, capabilities and supported controls, and can generate a monitor database XML file; scanning does not alter control values. The maker’s database index lists 474 monitor profiles in release 20260928. Packages are listed for Debian/Ubuntu, Fedora and openSUSE, alongside source releases and source builds. The project uses the GNU General Public License version 2.0 and directs support questions to GitHub Issues.
