I will like to see my hardware specs in my ubuntu desktop. Any ideas?
dmidecode is my go-to tool for finding out what hardware's on a machine. If you're just after basic info,
lspci touches most of the high notes.
sudo apt-get install lshw && sudo lshw
Or, if you want a graphical display:
sudo apt-get install lshw-gtk && sudo lshw -X
Try out HardwareLiSter. It can provide output on the command line, as HTML, and also has a GUI app.
This question has been discussed. There are some additional answers here: How to find out details about hardware on the Linux machine?
