How to check drivers in linux

How do I check the status of my drivers and install them if needed? [duplicate]

I’m trying to learn how to use Ubuntu, but I must say I didn’t have half as many issues with 16 as I have had with 18.04

I’m using a laptop and I’m at a beginner-level. (But I’m willing to learn) And basically I’m having a lot of lag, and perhaps I don’t have the correct drivers.

I’d need an easy command to pull up my system info, and then run a check on my drivers and download what’s needed.

Proc: AMD e1-1200 APU with Radeon HD graphics x2, Mem: 3.5m total, 1.7g used, 651m free, Swap: 3.6g total, 29m used, 3.6g free

CPU MHz: 778.147, CPU max MHz: 1400.0000, CPU min MHz: 777.0000

This has been answered before but in two parts.

First displaying loaded kernel modules.

Linux (and Ubuntu as well) doesn’t have separate entity as «device drivers», Linux has kernel modules which could be called «drivers» for real or virtual hardware depending on their functionality.

Use lsmod or cat /proc/modules to see list of loaded kernel modules. Also you can see list of all available (installed) kernel modules in system using:

Next, using Software Sources > Additional Drivers, for installing device drivers, often proprietary.

Unity (15.10 and 15.04/14.04/13.04/14.10/13.10/12.10)

Click on the gear icon on the top right corner of your screen and click on «System Settings» from that menu, click on Software Sources (or you can click on the Ubuntu button and search for «Sources»:

Linux: How to find the device driver used for a device?

If my target has one device connected and many drivers for that device loaded, how can I understand what device is using which driver?

8 Answers 8

Example. I want to find the driver for my Ethernet card:

First I need to find coordinates of the device using lspci ; then I find driver that is used for the devices with these coordinates.

sudo lspci -v will show it. like this:

You can also combine it with grep like this:

For USB based devices you can see the driver name by using the lsusb command:

And/or you use lshw which enumerates the devices on all buses including USB, PCI, etc so you can see which driver it uses:

If you just want to plainly use sysfs and doesn’t want to deal with all these commands which eventually looks inside sysfs anyways, here’s how:

say, what is the module/driver for eth6? «sfc» it is

or better yet.. let readlink resolve the path for you.

so. to figure out what are the drivers for all of your network interfaces:

You can use the lsmod command to get the status of loaded modules / devices drivers in the Linux Kernel.

For a specific device, you can use dmesg |grep to get the details too.

How to check the information of current installed video drivers?

My CPU usage is high when I do trivial things such as scrolling through a PDF file. So I think my video driver is not properly installed.

I want to confirm that by checking the information of my currently installed video driver, such as if there’s a driver installed and what version it is. Then I could decide whether to install a new one if it is not up to date.

On Windows, I could use the device manager, how to do that on Ubuntu Linux? I don’t expect a GUI solution for this. Command line will be just good enough.

In Linux, there is two parts for the video driver, the kernel part and the X server part.

1. Let’s identify your hardware first. By typing lspci | grep VGA in a terminal, you should see a line with you graphic card description (even if not configured at all).
2. Let’s check the correct kernel driver is loaded find /dev -group video .
3. Let’s check the correct X driver is loaded glxinfo | grep -i vendor .

If you want more help, I would like the result of following commands: (Remember, never trust command line that people ask you to execute without knowing what it does.)

The easiest way is to run

This command will show all video PCI devices and kernel modules installed and in use.

Only VGA is not good enough, because Nvidia mobile adapters are shown as 3D and some AMD adapters are shown as Display .

How can I check the information of currently installed WiFi drivers?

When I clicked on additional drivers on Ubuntu 12.04, I could not see any drivers.. How can I check what drivers are installed for WiFi on Ubuntu environment.

5 Answers 5

The following commands are run in a terminal. Open one by Ctrl + Alt + T .

To check what drivers your wireless adapter is currently using, you may run the following command:

• lshw lists information on your hardware
• -C network filters the output to only show the network class.

In the output, look for the entry with description: Wireless interface .

Here’s the output from my Ubuntu:

In the configuration line (line before last), you’ll see the driver currently being used by my card. I’ve highlighted it in the output.

Alternatively, you can use the command:

• lspci lists information on your PCI connected cards
• -nnk instructs lspci to output more information about these cards (including the driver being used)
• | pipes the output to the next command
• grep 0280 filters the output to show lines containing 0280 , which is the PCI class code for wireless PCI controllers in Ubuntu.
• -A2 shows two more lines of information.

Here’s the output from my Ubuntu:

Once you determine the driver you’re using, you can use the following command to show more information about it:

To check what wireless drivers you currently have installed, but not necessarily being used by anything, you can do the following command:

The above command will list all drivers you have installed. This will probably be an exhaustive list, because these are preinstalled drivers on your Ubuntu to make it possible for people to use their wireless drivers as soon as they install Ubuntu.

Linux Find Out Graphics Card Installed In My System

I am a new Linux system user and Ubuntu Linux. I do not want to open up the computer hardware to just see the make and model of the graphics card in a system. How do I find out which graphics card installed in my Linux desktop or laptop system?

You do not have to open the hardware, desktop, laptop computer powered by Linux to see the make and model of the graphics card in a system. There is a direct method provided by using lspci and other commands on Linux to get hardware information. You need to use the following commands to find out graphics cards in Linux using the CLI and GUI methods:

Tutorial details
Difficulty level	Easy
Root privileges	Yes
Requirements	Linux
Est. reading time	6 mintues

1. lspci command
2. lshw command
3. grep command
4. update-pciids command
5. GUI tools such as hardinfo and gnome-system-information command.

Linux Find Out Graphics Card Information

First you need to update the PCI ID database.

Download the latest version of the PCI ID list

Grab the current version of the pci.ids file from the Internet:
$ sudo update-pciids
OR
# update-pciids
Sample outputs:

How to check graphics card on Linux

Type the following lspci command. It will usually tell you the vendor and model of your card. Open the Terminal/xterminal or shell prompt and type the command:
$ lspci
$ lspci -v
$ lspci -v | less

Sample outputs:

Look for video controller / vga / 3D keywords in above output listing. Please note that if you do not see your card, try updating pci database. It is a good idea to run update-pciids command to fetches the current version of the pci.ids file from the primary distribution site and installs it. You must run update-pciids command as root user:
$ sudo update-pciids
OR
# update-pciids

Example: Find out the model of my graphics card on my Laptop powered by Linux

Type the following lspci command along with grep command or egrep command:
$ lspci | grep -i —color ‘vga\|3d\|2d’
## using egrep ##
$ lspci -v | egrep -i —color ‘vga|3d|2d’
Sample outputs:

Please note the device ID # 01:00.0. Now, to get detailed information, enter:
$ sudo lspci -v -s 01:00.0
Sample outputs:

A note about Nvidia GPU users with Nvidia binary drivers

Just type the following command to get detailed information about NVIDIA GPU card:
$ nvidia-smi
Sample outputs:

We can use GUI tool called nvidia-settings. It is a tool for configuring the NVIDIA graphics driver and give informaion. It operates by communicating with the NVIDIA X driver, querying and updating state as appropriate. This communiction is done via the X extensions. For example, open the terminal app and then type:
$ nvidia-settings

Linux Find Out GPU Information Using the glxinfo

Run the following glxinfo command on Linux to find GPU name, vendor, video card RAM size and more:
$ glxinfo -B

Finding graphics cards on Linux Laptops

Many laptops have two GPUs like integrated Intel and dedicated Nvidia/AMD card. In any case you need to use the lspci command as follows:
sudo lspci -v | more
sudo lspci -v | most
sudo lspci -v | grep -i vga

So I have Hybrid-graphics. It is nothing but two graphics cards on same computer. Typically Laptop comes with two graphic cards with different power consumptions on a single system. In this case I have both Intel and Nvidia GPUs. In such case I can select card using the prime-select command:
prime-select intel
prime-select nvidia
prime-select on-demand
prime-select query
See lspci command man page here for more info and read NVIDIA Optimus and Bumblebee for details about NVidia using hybrid graphics with NVidia’s proprietary driver here.

Conclusion

This page listed various Linux commands to find out graphics card (GPU) using the command line options. Once you know about GPUa desktop or laptop computer has, you can install the correct driver on Linux.
