In their own words
ddcutil
ddcutil is a free Linux program for controlling monitor settings such as brightness, color levels and input source. It communicates with monitors through DDC/CI over I²C and supports monitors implementing MCCS over USB. Commands can find monitors, show capabilities, read or change VCP feature values, and save or restore color-related settings. The companion ddcui provides a Qt graphical interface with Summary, Capabilities and Features views, with the last allowing changes to modifiable values. For profile workflows, dumpvcp saves current settings to a file and loadvcp restores them. Developers can use the C API through libddcutil.so to read and write VCP values and handle profile-related features. The program is released under GNU GPL version 2. Setup requires the Linux kernel i2c-dev module, and non-root users need permissions to run it. It does not support laptop displays, which use a special API rather than I²C, and generally will not run in virtual machines because virtual video drivers do not implement I²C. For MCCS-over-USB table features, support is limited; the capabilities command synthesizes a response.
