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\[u2013]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).
OPTIONS

When applicable the animation speed can be set with --speed=value, where the allowed
values are: fast, medium, slow.
The animation direction can be set with --direction=value, where the allowed values are:
forward or backward. --start-led=number, the first LED that the lighting effect should be
for. --start-led=number, the first LED that the lighting effect should be for.
--maximum-led=number, the number of LEDs that the lighting effect should applied to.
--temperature-sensor=number, The temperature sensor that should be used to control the fan
curves, probe 1 by default.

The rainbow mode speed can be configured with --speed=[1–6]. The speed of the other modes
is instead customized with --time-per-color (fading and blinking) and --time-off
(blinking only).
All modes except blackout support a visual high-temperature alert configured with
--alert-threshold and --alert-color.

Setting a fixed fan speed changes the fan mode to software control. To revert back to
hardware control, run initialize again.
(Experimental feature) The +12V rails normally function in multiple-rail mode. Single-
rail mode can be selected by passing --single-12v-ocp to initialize. To revert back to
multiple-rail mode, run initialize again without that flag.
