GNU GV is a graphical user interface to the Ghostscript interpreter. With it, one can view and navigate through PostScript and PDF documents in X Windows.

GNU gxmessage is a program that pops up dialog windows, which display a message to the user and waits for their action. The program then exits with an exit code corresponding to the response.

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.

Memtest86+ is a thorough, stand-alone memory test for x86 systems. 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.

It runs independently of any operating system, at computer boot-up, so that it can scan as much of your RAM as possible for hardware defects.

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.

Brillo is a command line tool to control the brightness of backlight and LED devices on Linux.

Notable features include:

• Automatic best controller detection

• Smooth transitions and natural brightness adjustments

• Ability to save and restore brightness across boots

• Directly using sysfs to set brightness without relying on X

• Unprivileged access with no new setuid binaries

• Containment with AppArmor

OpenHMD aims to provide an API and drivers for immersive technology, such as head mounted displays with built in head tracking.

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.

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.

ddcui is a graphical user interface for ddcutil, implemented using Qt. It provide a dynamic way to inspect and configure external monitors through the Display Data Channel Command Interface (DDC/CI) protocol.

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

ckb-next is a driver for Corsair keyboards and mice. It aims to bring the features of Corsair's proprietary software to Linux-based operating systems. It already supports much of the same functionality, including full RGB animations.

This is the Python extension to usbrelay, a Linux driver based on hidapi for a variety of inexpensive HID compatible USB relay modules. This package also includes usbrelayd.

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.

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.

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.

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.

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.

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

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.

HwInfo is used to probe for the hardware present in the system. It can be used to generate a system overview log which can be later used for support.

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.

USBGuard is a software framework for implementing USB device authorization policies (what kind of USB devices are authorized) as well as method of use policies (how a USB device may interact with the system). Simply put, it is a USB device whitelisting tool.

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