What are drivers on Linux?

Linux kernel device drivers are essentially a shared library of privileged, memory-resident, low-level hardware management routines. It is the Linux device drivers that handle the specifics of the devices they manage. One of the fundamental characteristics of is that it abstracts from device management.

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

You’re thinking of apps that run in the Windows environment. I’m not aware of anything similar in the Ubuntu/Linux environment. Maybe, describe more about your «lag» and we might come up with some ideas on how to cure that. Does the lag happen all of the time? Only in one app? When you’re running a VPN? Etc.

I’ll have to read more about the kernal system and the major differences between Linux and Windows, to better understand. But basically, my system is very slow upon installing ubuntu 18.04. Namely, application windows slowly opening, webpages and while trying to play Minecraft. Generally the entire system seems slow.

What processor? What speed? How much RAM/swap? What video subsystem/drivers? Edit your question to show me free -h .

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:

ls -R /lib/modules/`uname -r`/kernel/ 

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»:

and then on the Additional drivers tab:

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:

$ sudo lspci . 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) $ find /sys | grep drivers.*02:00 /sys/bus/pci/drivers/r8169/0000:02:00.0 

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

I know the OP asked for «drivers being used», but what if the driver is not installed nor being used? How to find out just by the vendorID:productID ? Also, what if it is not a PCI device, and you only see it in lsusb for example?

@DrBeco: But if driver is not installed, what do you want to find? You should just google in this case

#!/bin/bash for f in /sys/class/net/*; do dev=$(basename $f) driver=$(readlink $f/device/driver/module) if [ $driver ]; then driver=$(basename $driver) fi addr=$(cat $f/address) operstate=$(cat $f/operstate) printf "%10s [%s]: %10s (%s)\n" "$dev" "$addr" "$driver" "$operstate" done 

$ ~/what_eth_drivers.sh eth0 [52:54:00:aa:bb:cc]: virtio_net (up) eth1 [52:54:00:dd:ee:ff]: virtio_net (up) eth2 [52:54:00:99:88:77]: virtio_net (up) lo [00:00:00:00:00:00]: (unknown) 

I’d like to find solution which would find also veth and other virtual drivers. IMHO the only solution is to use ethtool or lshw .

sudo lspci -v will show it. like this:

$ sudo lspci -v 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. . Kernel driver in use: radeon Kernel modules: radeon 

You can also combine it with grep like this:

$ sudo lspci -v | grep -A 20 VGA 

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:

FTR: the driver is shown at line titled configuration , for example: configuration: driver=btusb maxpower=100mA speed=12Mbit/s

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

# ls -l /sys/class/net/eth6/device/driver lrwxrwxrwx 1 root root 0 Jan 22 12:30 /sys/class/net/eth6/device/driver -> ../../../../bus/pci/drivers/sfc 

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

# readlink -f /sys/class/net/eth6/device/driver /sys/bus/pci/drivers/sfc 

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

# ls -1 /sys/class/net/ | grep -v lo | xargs -n1 -I<> bash -c 'echo -n <> :" " ; basename `readlink -f /sys/class/net/<>/device/driver`' eth0 : tg3 eth1 : tg3 eth10 : mlx4_core eth11 : mlx4_core eth2 : tg3 eth3 : tg3 eth4 : mlx4_core eth5 : mlx4_core eth6 : sfc eth7 : sfc eth8 : sfc eth9 : sfc
