How to get the GPU info?

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.

That type of information is non-standard, and the tools you will use to gather it vary widely.

The command glxinfo will give you all available OpenGL information for the graphics processor, including its vendor name, if the drivers are correctly installed.

To get clock speed information, there is no standard tool.

• For ATI/AMD GPUs running the old Catalyst driver, aticonfig --odgc should fetch the clock rates, and aticonfig --odgt should fetch the temperature data. I'm not familiar with AMDGPU-Pro, but a similar tool should exist.
• For NVIDIA GPUs, the nvidia-smi tool will show all of the information you could want, including clock speeds and usage statistics.

I am not aware of an equivalent tool for the open source drivers or for Intel or other GPUs, but other information on the hardware can be fetched from the lspci and lshw tools.

A blog post focusing 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 and 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.
