NAME¶

gddccontrol - 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.

SEE ALSO¶

The program is documented fully in
