The i7z utility accurately measures the current frequency and temperature of older Intel Core (i3, i5, and i7) processors including the Nehalem, Sandy Bridge, and Ivy Bridge generations. Reliable support for newer CPUs is not guaranteed, as this package has not seen significant development since 2013.

If your processor is supported, you'll get detailed reports on Turbo Boost and clock multipliers, core voltage, and time spent in different C-states. This information can be viewed in real time and/or logged to a file.

Liquidctl is a package with tools, drivers and a Python library to work with liquid cooling equipment such as AIO coolers, fan controllers and other devices.

This is a program for testing the quality of CRT/LCD screens. It displays various patterns and allows you to estimate the quality of your CRT/LCD monitor.

This package provides tools for LAN eXtensions for Instrumentation based on the LXI Consortium standard which defines the communication protocols for modern instrumentation and data acquision systems using Ethernet.

ddcutil can query and modify most external monitors' settings, such as brightness, colour levels, and input sources. Generally speaking, any setting that can be changed by pressing buttons on the monitor can be modified by ddcutil.

ddcutil communicates directly with monitors implementing the Monitor Control Command Set (MCCS). It usually does so through the the Display Data Channel Command Interface (DDC/CI) protocol on the I2C bus, but can also communicate over USB as per the USB Monitor Control Class Specification.

One particular use case is in colour profile management. Monitor calibration is relative to the monitor colour settings currently in effect, e.g. red gain. ddcutil allows colour-related settings to be saved at the time a monitor is calibrated, and restored when the calibration is applied.

This package includes udev rules that can be used by adding this package to the rules field of the udev-configuration record. It gives read/write access to i2c devices to users in the i2c group.

Hueplusplus is a library for controlling Philips Hue lights. Features:

• find bridges with SSDP or set an ip manually

• all common light functions (brightness, color, temperature)

• extended alert() functions, which alert in a specific color (good for notifications)

• supports sensors, rules, groups, scenes and schedules

• streaming with entertainment mode

• documented with doxygen

Headsetcontrol is a tool to control certain aspects of USB-connected headsets. Currently, support is provided for adjusting sidetone, getting battery state, controlling LEDs, and setting the inactive time.

This library offers a simple API for communicating with instruments compatible with the LXI standard that defines communication protocols for instrumentation and data acquisition systems using Ethernet. Applications can use liblxi to discover instruments on your network, send SCPI commands, and receive responses.

Rkdeveloptool can read from and write to RockChip devices over USB, such as the Pinebook Pro.

This package provides the TCG TSS2. The stack contains libtss2-fapi, libtss2-esys, libtss2-sys, libtss2-mu, libtss2-tcti-device, libtss2-tcti-swtpm and libtss2-tcti-mssim.

libsmbios provides a library to interface with the SMBIOS tables. It also provides extensions for proprietary methods of interfacing with Dell specific SMBIOS tables.

The h-node project (https://www.h-node.org) aims to build a database of hardware that works with fully free operating systems. h-client is a GTK+ graphical client that is able to retrieves information on the hardware inside the computer it's running on, and on peripherals connected to it, and helps you submit that information to the h-node project along with whether the hardware works with a fully free operating system or not.

OpenRGB is lighting control that doesn't depend on manufacturer software. ASUS, ASRock, Corsair, G.Skill, Gigabyte, HyperX, MSI, Razer, ThermalTake, and more supported.

Features:

• Set colors and select effect modes for a wide variety of RGB hardware

• Save and load profiles

• Control lighting from third party software using the OpenRGB SDK

• Command line interface

• Connect multiple instances of OpenRGB to synchronize lighting across multiple PCs

• Can operate standalone or in a client/headless server configuration

• View device information

• No official/manufacturer software required

• Graphical view of device LEDs makes creating custom patterns easy

Read temperature from usbtemp.com USB thermometer and DS9097E compatible 1-wire adapter with one DS18B20 digital probe attached through command line interface.

This is a Linux driver based on hidapi for a variety of inexpensive HID compatible USB relay modules available with different number of output relays.

This package provides a Guile Scheme API to control USB HID relay modules produced by dcttech.

Hardware Probe is a tool to probe for hardware, check its operability and find drivers.

Libcpuid is a small C library to get vendor, model, branding string, code name and other information from x86 CPU. This library is not to be confused with the cpuid command line utility from package cpuid.

Deskflow is a keyboard and mouse sharing app. Use the keyboard, mouse,or trackpad of one computer to control nearby computers, and work seamlessly between them. It's like a software KVM (but without the video). TLS encryption is enabled by default. It supports Wayland clipboard sharing.

Memtester stress-tests the memory subsystem of your operating system and computer. It repeatedly writes different patterns to all memory locations, reads them back again, and verifies whether the result is the same as what was written. This can help debug even intermittent and non-deterministic errors.

Memtester runs entirely in user space. This means that you don't need to reboot to test your memory, but also that it's not possible to test all of the RAM installed in the system.

It can also be told to test memory starting at a particular physical address.

This package provides tools for exploring Nvidia's proprietary GPU drivers, including an assembler and a disassembler for several GPU instruction sets, and tools to deal with register databases.

edid-decode decodes EDID monitor description data in human-readable format and checks if it conforms to the standards.

The MSR Tools project provides console utilities to directly access the Model-Specific Registers (MSRs) and CPU ID of Intel-compatible processors:

• cpuid: show identification and feature information of any CPU

• rdmsr: read MSRs from any CPU or all CPUs

• wrmsr: write to MSRs on any CPU or all CPUs

These tools can be used to query and modify certain low-level CPU parameters, such as the Turbo Boost ratio and Thermal Design Power (TDP) limits.

MSR addresses differ (greatly) between processors, and any such modification can be dangerous and may void your CPU or system board's warranty.

Wavemon is a wireless device monitor with an interactive ncurses terminal interface. It can display and plot signal and noise levels in real time. It also reports packet statistics, device configuration, network parameters, and access points and other wireless clients of your wireless network hardware.

Wavemon should work (with varying levels of detail and features) with any device supported by the Linux kernel.
