DxDiag ("DirectX Diagnostics") is a diagnostics tool used to test DirectX functionality and troubleshoot video- or sound-related hardware problems. DirectX Diagnostic can save text files with the scan results. These files are often posted in tech forums or attached to support emails in order to give support personnel a better idea of the PC the requester is using in case the error is due to a hardware failure or incompatibility.

DRIconf is a configuration applet for the Direct Rendering Infrastructure.

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.

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.

Yacpi is an acpi monitoring program for Linux. It displays various acpi information like battery status and ac status on notebooks. The main reason why i wrote this program is, because i don't like the acpi program, which is included in debian :) It displays things like battery status, ac status, cpu frequency, remaining battery/charge time, temperature... It also supports the use of more than one battery and can display them.

hddtemp is a small utility (daemonizable) that gives you the temperature of your hard drive by reading S.M.A.R.T. informations (for drives that support this feature).
