hwinfo!

Also known as palimpsest, gnome-disk-utility provides libraries and applications for dealing with storage devices.

Hardinfo is a system information and benchmark tool for Linux. It shows detailed system info, including hardware, environment, and kernel. It can use lm_sensors and ACPI for temperature and battery information. It also has four CPU banchmarks and two FPU benchmarks. It can generate reports as well.

Psensor is a graphical hardware temperature monitor for Linux. It can monitor the temperature of the motherboard and CPU sensors (using lm-sensors), the temperature of the NVidia GPUs (using XNVCtrl), the temperature of ATI/AMD GPUs, the temperature of the Hard Disk Drives (using hddtemp or libatasmart), the rotation speed of the fans (using lm-sensors), the CPU usage (since 0.6.2.10 and using Gtop2).

lshw (Hardware Lister) is a small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or EFI (IA-64) systems and on some PowerPC machines.

A helping tool for udev testers, coders, hackers and consumers. Main features are - Browsing the sysfs tree via udev, Reports udev device info and udev properties, Filter and search devices, Monitorize udev device events.

cpuid dumps detailed information about the CPU(s) gathered from the CPUID instruction, and also determines the exact model of CPU(s).

read-edid is a pair of tools (originally by John Fremlin) for reading the EDID from a monitor. It should work with most monitors made since 1996 (except for newer ones with 256-byte EDID's - WiP), assuming the video card supports the standard read commands (most do).read-edid is a set of two tools - get-edid, which gets the raw edid information from the monitor, and parse-edid, which turns the raw binary information into an XF86Config-compatible monitor section.

Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard. This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

inxi is a command line system information script built for for console and IRC. It is also used for forum technical support, as a debugging tool, to quickly ascertain user system configuration and hardware. inxi shows system hardware, CPU, drivers, Xorg, Desktop, Kernel, GCC version(s), Processes, RAM usage, and a wide variety of other useful information.

DRIconf is a configuration applet for the Direct Rendering Infrastructure. It allows customizing performance and visual quality settings of OpenGL drivers on a per-driver, per-screen and/or per-application level. The settings are stored in system wide and per-user XML configuration files, which are parsed by the OpenGL drivers on startup.

glxinfo is a command-line tool that can help you diagnose problems with your 3D acceleration setup. It can also provide additional helpful information for developers.

Creates a list of attached disks without root privileges (similar as ldisk -lu, but with extensive device information).

Uses information in sysfs (Linux kernels 2.6.0 and later) to list all scsi devices (or hosts) currently attached to the system. Options can be used to control the amount and form of information provided for each device.

vbetool is a small application that executes code from the BIOS of your video card. This is mostly useful for reinitialising the hardware, for instance after ACPI suspend/resuming.
