How can I find what video driver is in use on my system?

• http://askubuntu.com/questions/23238/how-can-i-find-what-video-driver-is-in-use-on-my-system

I know that sometimes I have the option to change my video display driver, and I can access this functionality by using System->Administration->Additional Drivers. But what's the simple way to see what driver my Ubuntu 10.04 or 10.10 system is using currently?

UPDATE -- I found a command I didn't know about in How to determine version and origin of proprietary drivers.

jockey-text -l

Martin Owens gives this example output:

kmod:nvidia_current - nvidia_current (Proprietary, Enabled, Not in use)
pkg:sl-modem-daemon - Software modem (Proprietary, Disabled, Not in use)

kmod stands for kernel module, pkg is obviously an apt package. According to the code, jockey installs the latest candidate package and ignores any detectable kernel modules or blacklisted modules.

The output is more descriptive than that from lshw by itself, but I think it is limited to giving information about drivers that were installed with jockey in the first place. Jockey, launched as jockey-gtk, is (I believe) the same application that runs when you select System->Administration->Additional Drivers .

Run lshw -c video, and look for the line with "configuration". The loaded driver is prefixed with "driver=". Example output:

 *-display
      description: VGA compatible controller
      product: Core Processor Integrated Graphics Controller
      vendor: Intel Corporation
      physical id: 2
      bus info: pci@0000:00:02.0
      version: 02
      width: 64 bits
      clock: 33MHz
      capabilities: vga_controller bus_master cap_list rom
      configuration: driver=i915 latency=0
      resources: irq:45 memory:fd000000-fd3fffff memory:d0000000-dfffffff ioport:1800(size=8)

If you want more information about the loaded driver, run modinfo. Output of modinfo i915:

filename:       /lib/modules/2.6.35-24-generic/kernel/drivers/gpu/drm/i915/i915.ko
license:        GPL and additional rights
description:    Intel Graphics

depends:        drm,drm_kms_helper,video,intel-agp,i2c-algo-bit
vermagic:       2.6.35-24-generic SMP mod_unload modversions 

Note that modinfo works on filenames and aliases, not on module names. The majority of the modules will have the same name for the module name and filename, but there are exceptions. One of them is nvidia.

Another way of using these commands in order to show you the file name of the driver would be:

modinfo -F filename `lshw -c video | awk '/configuration: driver/{print $2}' | cut -d= -f2`

When loaded, the command lsmod will show the nvidia module as loaded. modinfo nvidia will error out. Why? Because there is no alias "nvidia" and the module is placed in /lib/modules/3.2.0-32-generic/updates/dkms/nvidia_current.ko. You have to use modinfo nvidia_current in this case. (note that modinfo automatically converts - to _, so modinfo nvidia-current is equivalent.)

Use modinfo. If you want to have more information about the i915 driver, run: modinfo i915.

lshw -c video 

does show me the driver details as nvidia

You could use the following command to see the currently used vga kernel driver:

lspci -nnk | grep -i vga -A3 | grep 'in use'

Example output for an ATI / AMD graphic card:

if the open source Radeon driver is used:

Kernel driver in use: radeon

if the proprietary Fglrx driver is used:

Kernel driver in use: fglrx_pci

Complete Output with

lspci -nnk | grep -i vga -A3:

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Mobility Radeon HD 2400 [1002:94c9]
Subsystem: Toshiba America Info Systems Device [1179:ff00]
Kernel driver in use: fglrx_pci
Kernel modules: fglrx, radeon

Available kernel modules you can see with

lspci -nnk | grep -i vga -A3 | grep 'Kernel modules':

Kernel modules: fglrx, radeon

Note: This does not work in every case!

For a SiS 65x/M650/740 PCI/AGP VGA Display Adapter, there is no "Kernel driver in use" line:

lspci -nnk | grep -i vga -A2

01:00.0 VGA compatible controller [0300]: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter [1039:6325]
Subsystem: ASUSTeK Computer Inc. Device [1043:1612]
Kernel modules: sisfb

and the available sisfb kernel module is not the loaded driver, because lsmod | grep sisfb has no output (sisfb is blacklisted). In this case also sudo lshw -c video | grep Konfiguration does not work. The output is:

Konfiguration: latency=0

without any driver information.

One reason is that I have Nvidia Optimus card and that makes thing harder so I added optirun before the command. shareimprove this answer

How to determine the version and origin of proprietary drivers installed by Additional Drivers?

• http://askubuntu.com/questions/20531/how-to-determine-the-version-and-origin-of-proprietary-drivers-installed-by-addi

How can I tell which version and from which repository the Additional Drivers tool is trying to install the fglrx graphics driver?

It says that I have a different version of the driver in use. I installed the driver from maverick/restricted and apt-cache tells me it's from a regular Ubuntu mirror. The installed version is the same as the candidate version.

Can I get Additional Drivers to tell me what it would install if I activated the driver through it? Is it possible Additional Drivers just assumes it's a different version since it was installed by a different process?

10.10 package-management drivers proprietary

The "Additional Drivers" (aka jockey-gui) GUI tool can't tell you much and it can be easily confused. If you've used cli commands to install the right driver then you don't need to use the gui tool.

It sounds like you know how to use apt-cache to search for the versions available.

So use jockey-text to find the list of drivers and the packages:

jockey-text -l

On my machine this looks like:

kmod:nvidia_current - nvidia_current (Proprietary, Enabled, Not in use)
pkg:sl-modem-daemon - Software modem (Proprietary, Disabled, Not in use)

kmod stands for kernel module, pkg is obviously an apt package. According to the code, jockey installs the latest candidate package and ignores any detectable kernel modules or blacklisted modules.

I have tried many ways without succes, but this did work on me (Ubuntu 12.10):

/usr/lib/nux/unity_support_test --print

One reason is that I have Nvidia Optimus card and that makes thing harder, so I added optirun before the command.

lshw -c video

Install NVIDIA GeForce driver in Ubuntu 13.10 / 13.04 / 12.10 / 12.04 using PPA

• http://www.howopensource.com/2012/10/install-nvidia-geforce-driver-in-ubuntu-12-10-12-04-using-ppa/

nstall the latest NVIDIA GeForce graphics driver (version 304.108 / 319) in Ubuntu 13.10 / 13.04 / 12.10 / 12.04 / 11.10 / 11.04 / 10.04 using PPA. This PPA doesn’t support Ubuntu 10.10. This PPA is from Ubuntu-X team and xorg crack pushers team which updates unsupported packages for your system.

For Ubuntu 10.10 you can download the latest NVIDIA GeForce graphics driver (version 304.64) from GeForce official site.

To add PPA for Ubuntu 13.10 / 13.04 / 12.10

Ubuntu 13.10 / 13.04 / 12.10 users, Run the following command in the terminal and type the password for the user when prompted. Others use the Ubuntu-X PPA.

sudo apt-add-repository ppa:xorg-edgers/ppa

To add PPA for Ubuntu 12.04 / 11.10 / 11.04 / 10.04

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates

After adding the PPA, update your system repository.

sudo apt-get update

Now install the NVIDIA GeForce graphics driver 304.108 in your system, as you install other packages by using apt-get.

sudo apt-get install nvidia-current nvidia-settings

Above command will install the driver.

In Ubuntu X you can see the latest and stable release drivers

most latest and stable release

Open dash with the Super Key.

Start typing
