DESCRIPTION
liquidctl is a utility for overseeing and controlling some hardware monitoring devices not yet supported at the kernel level. Because liquidctl directly accesses the hardware devices, root privileges are generally required, though this can be avoided with appropriate udev rules.

liquidctl list outputs all compatible devices found on the system. In case more than one device is found, the desired one can be selected for later invocations with --match=substring, where substring matches part of the desired device's description using a case insensitive comparison.

liquidctl list --verbose enables the display of additional identifiers and addresses that can also be used to select specific devices. These can be better suited for certain use cases, such as non-interactive scripts.

liquidctl initialize prepares a device for later commands, and most devices must be initialized after every boot or when resuming from a suspended state. Unless finer control is required, all devices can be initialized at once with liquidctl initialize all. Some devices may output some information at this stage.

liquidctl status displays the status of all devices that match the provided filtering options.

liquidctl set channel speed allows the user to set fan and pump speeds. These, depending on the device, can be set to fixed duty values, variable temperature–duty curves, or both.

liquidctl set channel color allows the user to configure and set lighting modes. Supported lighting modes and additional options vary by device and are listed in later sections of this manual. Each color can be specified as:

•   hexadecimal RGB with or without prefix '0x': ff7f3f;

•   decimal RGB triple, R,G,B ∊ [0, 255]: rgb(255,127,63);

•   hue-saturation-value HSV triple, H ∊ [0, 360], S,V ∊ [0, 100]: hsv(20,75,100);

•   hue-saturation-lightness HSL triple, H ∊ [0, 360], S,L ∊ [0, 100]: hsl(20,100,62).

liquidctl set channel screen allows the user to configure the LCD screen integrated into some AIO models.

liquidctl automatically detects when a kernel driver is bound to the device and, whenever possible, uses it instead of directly accessing the device. Alternatively, direct access to the device can be forced with --direct-access.
