Yesterday I posted a list of terminal commands for gathering information about your system from the command line. For today, here are a few graphical utilities for the same job.
Install from the package sysinfo
Sysinfo has a nice and simple interface, but displays less information than some of the other software here. Some sections use a drop down area to reveals extra information. Sysinfo is great if it has the details you need.
Install from the package lshw-gtk
lshw-gtk is a graphical interface to the lshw utility. It sorts information into multiple scrolling lists. The launcher is hidden away in the System->Preferences menu, but you will get more data running from the command line with sudo. lshw-gtk provides fairly detailed reports.
Included in Ubuntu
Ubuntu has its own device manager included by default in the System->Preferences menu, which uses HAL to gather information. It’s not easy to sort through all the devices, but it provides lots detail and is available on every GNOME desktop.
