What is the equivalent of Windows System Properties or Device Manager?

I am new to Ubuntu. In Windows, if I want to know my system properties/configuration, I can see it by going to Control Panel and clicking on the System icon. I can also get a detailed list of the hardware detected/installed by going to the Device Manager.

What are the equivalents of these features in Ubuntu, where a user can see his or her system properties and hardware configuration, like RAM, CPU/processor, hard disk capacity, etc.?

Example of Windows System Properties:

Solution 1:

For Basic Information

Go to Settings, and under System, click on Details for basic information:

For Detailed Information (like Windows Device Manager)

• Search for "system" in Software Center, and install System Profiler and Benchmark:

  

• Then run it from the Launcher (type "system" if it isn't there already), and you will see a detailed list of hardware that you can expand further by category:

• This tool also allows you to run benchmarks to compare how your system performs relative to other common computers.

• Scroll down for examples of CPU and RAM information.

Other system-specific tools and console (terminal) tools

Please see Luis Alvarado's excellent exhaustive answer with screenshots to this question, just above or below this one.

Examples of CPU and RAM information as shown in System Profiler

Solution 2:

Open the terminal with Ctrl+Alt+T and type any of these:

For cpu info

cat /proc/cpuinfo  

For memory info

cat /proc/meminfo  

to see disk usage of various partitions

df -h  

See ram usage

free -m  

wireless network

iwconfig  

Which ubuntu is running in your computer

lsb_release -a  

Find your kernel info

uname -a  

list all hardware

sudo lshw  

All soundcards

aplay -l  

Some graphical software for the same will be

1)Hardware lister

Whenever you want to run it type sudo lshw-gtk in the terminal

Download it here

2)Sysinfo

3)System Profiler and Benchmark

Solution 3:

Without going into terminal commands (From my point of view, less friendly way of inviting a new user to Ubuntu.. until he/she feels the force) like:

lshw - Shows you information about all hardware
lsusb - Shows you information about all USB hardware
lspci - Shows information about all PCI compatible hardware
cat /proc/cpuinfo - Shows detailed information about your CPU
dmidecode - Shows you information about hardware

And others like lm-sensors or hdparm that can give information about HDD and temperature readings.

Seeing as you are new, I will mention easy to use GUI tools that can quickly help you find important information about your PC:

DISK UTILITY

Shows information about all type of storage devices, including but not limited to HDD, SDD, Flash Drives, External (Connected) USB Drives, etc..

To use it just open DASH (By pressing the SUPER key) and type disk. You will then see the option "Disk Utility".

DISK USAGE ANALYZER

Very good program to analyze the (As the obvious name implies) disk usage. It can very useful when doing a cleanup on old files and such.

As with Disk Utility, type in dash disk and the second option will be the "Disk Usage Analyzer"

Ubuntu Detail Information

Type in dash detail and you will see a cog icon with the name "Details". It will show you basic information on your machine:

I should mention that if you are using an Nvidia card, you need to update Ubuntu 12.04 with the latest upgrades in order to see the Video card name.

SYSINFO

Very nice program to see information about your computer.

It can be installed via the Software Center by looking for "Sysinfo" or "Hardware" or clicking here

HARDWARE LISTER

Very nice program based on LSHW to show you in a graphical way all the hardware. As the previous one I mentioned, it can also be installed from the Software Center by looking for "Hardware" or clicking here

So as you can see there are MANY programs to check for hardware and hardware information in general. I suggest playing with Software Center to find even more but this should be enough to know most if not everything about your computer.

Solution 4:

Try using hardinfo (System information and benchmarking tool)

Install via the terminal with:

sudo apt-get install hardinfo 

Or use the Software Center:

Invoke with the Dash and click on the summary tab
