Where installing the full version of Manjaro (i.e. complete with a pre-installed desktop environment, codecs, and software applications), the mhwd command will be automatically run by the CLI installer to automatically detect your graphics card and install the most appropriate driver for it. '''Whether free or proprietary drivers are installed will depend on your initial choice of using free or nonfree graphics drivers to boot up'''.  
Where installing the full version of Manjaro (i.e. complete with a pre-installed desktop environment, codecs, and software applications), the mhwd command will be automatically run by the GUI and CLI installer to automatically detect your graphics card and install the most appropriate driver for it.

Otherwise, it will be necessary to run the mhwd command manually as part of the post-installation process for the minimalistic '''NET-Edition''' of Manjaro. Of course, it is also possible to use the mhwd command to install, re-install, and remove installed graphics drivers at any time, as illustrated below.
'''For Beginners, it is recommended to use "Hardware Detection" in [[Manjaro Settings Manager]] to change or install new graphics drivers.'''
For intermediate and advanced users, it is also possible to use the mhwd command to install, re-install, and remove installed graphics drivers at any time, as illustrated below.

This is the recommended method for the detection and installation of graphics drivers. The syntax for the automated installation method is:


  sudo mhwd -a [pci or usb] [free or nonfree] 0300
  sudo mhwd -a [pci or usb connection] [free or nonfree drivers] 0300

Prior to manually installing a graphics driver, it will be necessary to identify what drivers are available for your system. To list the appropriate drivers available, the basic syntax is:
Prior to manually installing a graphics driver, it will be necessary to identify what drivers are available for your system. To list the appropriate drivers available, the basic syntax is:


  mhwd -l [optional: --pci or --usb]
  mhwd -l [optional: detailed view] [optional: --pci or --usb connection]




Using this command without the --pci or --usb filters will list all the available drivers for devices connected to your system. '''All drivers for graphics cards will have the prefix (video-) in their name'''. Otherwise, the following example will list only the drivers available specifically for devices (e.g. graphics cards) using an internal PCI connection:
Using this command without the additional options will list basic information for all the available drivers for devices connected to your system. '''All drivers graphics card drivers will have the prefix (video-) in their name'''. The basic information provided for all listed drivers will be:
 
* Name
* Version
* Free or proprietary, and
* PCI or USB connection


mhwd -l --pci


A more detailed list of installed drivers can be obtained by entering:


Irrespective of whether the optional filters is used or not, the following information will be displayed for all listed drivers:
mhwd -l -d
 
 
A detailed list will provide the following information:


* Name
* Name
* Version
* Version
* Free or proprietary, and
* PCI or USB connection
* PCI or USB connection
* Description
* Priority
* Free or proprietary
* Dependencies
* Conflicts
* Class ID (e.g. '0300' for graphics card drivers), and
* Vendor ID
In addition, using the ''--pci'' filter in the following example will list detailed information for only the drivers available for devices (e.g. graphics cards) using an internal PCI connection:
mhwd -l -d --pci

= Removing an Installed Driver =
= Removing an Installed Driver =
On occasion it may be necessary to remove an installed graphics card driver. Similarly to manually installing a graphics card driver, two steps should be undertaken for removal:
'''1.''' Identify the installed driver
'''2.''' Remove the identified driver
After all, it would be somewhat difficult to remove an installed driver if you don't know what it's called!
== Identifying Installed Drivers ==
To identify and list Manjaro's installed drivers - including the graphics driver to be removed, the syntax is:
mhwd  -li [optional: detailed view] [optional: pci or usb devices only]
Using this command without the additional options will list the basic information of all the drivers currently installed on your system. '''Once again, all drivers for graphics cards will have the prefix (video-) in their name'''. As with listing drivers available for your system, the ''-d'' option used in the following command will list detailed information:
mhwd -li -d
This information may prove useful to determine any otherwise unforeseen consequences or problems upon removing a driver. And again, it is also possible to filter your list of installed drivers by whether they are used on hardware connected via pci or usb. In this instance, a detailed list will be generated only for installed drivers used on hardware with a PCI connection:
mhwd -li -d --pci

To remove an installed driver, the syntax is:


  sudo mhwd -r [pci or usb] [name of driver]
  sudo mhwd -r [pci or usb] [name of driver]

= Enable or disable 32 bit support on 64 bit (multilib) =
If one does not do any gaming or use Wine for Windows based applications, 32 bit support can be removed from mhwd on 64 bit systems (multilib).
The following command will disable lib32 support from mhwd and prevent it from pulling lib32 packages:
sudo mhwd-gpu --setlib32 false
To enable:
sudo mhwd-gpu --setlib32 true

= Checking configuration =
You can check configuration with:
mhwd-gpu --check
mhwd-gpu --status
And if needed fix issues with:
mhwd-gpu --setgl
mhwd-gpu --setxorg
Make sure the path to xorg config file is valid.
Note about ati, xorg file and login artifacts or kicad: if you get artifacts upon logging in or if kicad rendering and zooming is slow, try adding [Option "EXAPixmaps" "off"] in the "Device" section of xorg config file. See [https://wiki.archlinux.org/index.php/ATI#Artifacts_upon_logging_in here.]
