Sfdwhf

I do not know of a direct equivalent, but lshw should give you the info you want, try:

sudo lshw -C display

(it also works without sudo but the info may be less complete/accurate)

You can also install the package lshw-gtk to get a GUI.

A blog post focussing on work done on the command-line is here:

http://www.cyberciti.biz/faq/howto-find-linux-vga-video-card-ram/

Find out the device ID:

 lspci | grep ' VGA ' | cut -d" " -f 1

03:00.0

You can then use this output with lspci again, forming two nested commands

lspci  -v -s  $(lspci | grep ' VGA ' | cut -d" " -f 1)

If you have more than 1 GPU card, try this equivalent command instead:

lspci | grep ' VGA ' | cut -d" " -f 1 | xargs -i lspci -v -s {}

Output from my system:

03:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 295] (rev a1) (prog-if 00 [VGA controller])

    Subsystem: NVIDIA Corporation Device 062e

    Flags: bus master, fast devsel, latency 0, IRQ 24

    Memory at f6000000 (32-bit, non-prefetchable) [size=16M]

    Memory at ec000000 (64-bit, prefetchable) [size=64M]

    Memory at f4000000 (64-bit, non-prefetchable) [size=32M]

    I/O ports at dc80 [size=128]

    [virtual] Expansion ROM at f7e00000 [disabled] [size=128K]

    Capabilities: <access denied>

    Kernel driver in use: nvidia

EDIT: You can avoid the <access denied> by launching with sudo

So, (prefetchable) [size=64M) indicates that I have a 64-MB NVIDIA card. However, I don't, it's rather 256 MB. Why? see below.

To see how to get the most info+performance out of it, read an extremely comprehensive article on the Arch-Linux Wiki

https://wiki.archlinux.org/index.php/NVIDIA

For nvidia users, start with

nvidia-smi

(This works with the Nvidia drivers installed,but not with systems running the open-source 'nouveau' driver).

This indicates that I have a 256 MB GDDR3 Graphics card.

At this time, I don't know how to get this for Intel and AMD/ATI GPUs.

Run google-chrome and navigate to the URL about:gpu.
If chrome has figured out how to use OpenGL, you will get extremely detailing information about your GPU.

For Nvidia cards.

1st GPU

clinfo

sudo apt-get install clinfo

clinfo

is the analogue of glxinfo but for OpenCL.

nvidia-settings

Mixes runtime with some static info.

More details: How do I check if Ubuntu is using my NVIDIA graphics card?

For Nvidia cards, type

nvidia-smi -q

I do believe the best option for this is neofetch.

# Get neofetch

sudo add-apt-repository ppa:dawidd0811/neofetch

sudo apt update

sudo apt get neofetch

# Run neofetch

neofetch

This gives an output like this:

Just to find the basics, according to https://wiki.debian.org/NvidiaGraphicsDrivers#NVIDIA_Proprietary_Driver,

lspci | grep VGA

If you need more detail than that, see @knb's answer to this same question.

This is really not that complex For model and memory, here's a 1 liner that works for every video card I've tested it on regardless of manufacturer (Intel, AMD, NVIDIA):

GPU=$(lspci | grep VGA | cut -d ":" -f3);RAM=$(cardid=$(lspci | grep VGA |cut -d " " -f1);lspci -v -s $cardid | grep " prefetchable"| cut -d "=" -f2);echo $GPU $RAM

GPU= All this bit does is grab the 3rd field from 'lspci' output filtered via 'grep' for VGA which corresponds to the video chip.

RAM= All this bit does is set variable cardid equal to the first field of output from lspci matching "VGA" and feeds that as a request for -v verbose output from lspci for that specific -s device, further filtering the output by grep for the string " prefetchable" as this contains the memory on the card itself (note the preceding space as we don't want to match "non-prefetchable" in our output.

For clock rate on Intel integrated graphics (Tested on I3 and I5)

execute the command sudo find /sys -type f -name gt_cur* -print0 | xargs -0 cat
This dives into the /sys tree to locate the gt_cur_freq_mhz
file which on my I3 is /sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_cur_freq_mhz and prints the content. which in my case under extremely light load is 350 as in 350 MHz which corresponds to the minimum frequency found in /sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_min_freq_mhz and when running glxgears and glmark2 results in
1050 as in 1050 MHz which corresponds to the maximum frequency found in /sys/devices/pci0000:00/0000:00:02.0/drm/card0/gt_max_freq_mhz

For clock rates on nvidia cards:

nvidia-smi -stats -d procClk corresponds to the GPU clock
nvidia-smi -stats -d memClk corresponds to the memory clock.

Note: I am unable to test the above as my trusty GeForce 210 isn't supported and this works only on Kepler or newer GPUs as indicated by
`nvidia-smi -stats --help'

I do not currently have any solutions for clock rate on AMD cards and do not have the hardware available for testing. I will however say that to the best of my knowledge the aticonfig mentioned in the accepted answer no longer exists and it appears that nvclock isn't available for anything since trusty.

In addition to neofetch answered previously, there is screenfetch which looks a lot nicer (IMO). Plus another answer mentions he doesn't know how to get iGPU listed and this does it:

For details on setup see: How can I get this terminal splash screen?

In summary just for the bottom section with Ubuntu display containing GPU information (second last line) use:

sudo apt install screenfetch

screenfetch

You'll want to put the screenfetch command an the bottom of your ~/.bashrc file to have it appear every time you open the terminal.

If you're running Ubuntu on a Chromebook with crouton, the only one of the answers that will work is going to chrome://gpu in the Chrome browser.

For the Intel GMA950 (comes with EeePC in particular) you can run:

setpci -s 00:02.0 f0.b

which will return '00' for 200MHz, '01' for 250MHz or '03' for 400MHz. You may be able to apply the same principle to other Intel cards.

If you would like to have simple information, you could try gpustat. It is very good and simple.

If you have a AMD Radeon Card, you may want to run the following commands

sudo update-pciids #optional command, requires internet

lspci -nn | grep -E 'VGA|Display'

It should report something like this

00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Wani [Radeon R5/R6/R7 Graphics] [1002:9874] (rev c5)

03:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / R7 M520] [1002:6660] (rev ff)

For nvidia GPUs, nvidia-smi command is your friend.
See man nvidia-smi if you like to.

For listing GPUs use nvidia-smi -L (nvidia-smi --list-gpus),
nvidia-smi -q give information about the gpu and the running processes.

Use lspci , lspci -v to get basic info see here.

In my case for ex once I run lspci and I have got :

dina@dina-X450LA:~$ lspci

In order to get all the information about the graphics processor, you can use the following command as specified by @greyfade.

> glxinfo

However, if the program glxinfo is currently not installed, you can install it by typing:

> sudo apt install mesa-utils

You will also have to enable the component called universe. Once this is done, glxinfo will list all the specifications related to the graphics processor in that environment.
