gddccontrol - Man Page
A graphical utility to control monitor parameters via software
Synopsis
gddccontrol [options]
Description
This manual page documents briefly the gddccontrol command.
gddccontrol is an open source utility which allows controlling monitor parameters via software.
Options
As a GTK3 application, gddccontrol accepts the standard GTK3 options.
- --hide-unsupported-warning
Do not show the warning banner for unsupported monitors when a fallback profile is used.
- -v, --verbose
Increase verbosity. Repeat (e.g. -vv) for more detailed output.
Environment
- DDCCONTROL_NO_DAEMON
When set to a non-empty value, gddccontrol bypasses the D-Bus daemon and accesses /dev/i2c-* devices directly. This can be useful for testing, debugging, or working around a daemon startup or connection problem.
- GTK_THEME
Override the GTK theme for this launch. For example, run GTK_THEME=HighContrastInverse gddccontrol to use the GTK high-contrast dark theme when it is installed. If running through sudo, use sudo env GTK_THEME=HighContrastInverse gddccontrol.
