'''All drivers graphics card drivers will have the prefix (video-) in their name'''. The basic information provided for all listed drivers will be: | ||
mhwd -l - | * Name | ||
* Version | |||
* Free or proprietary, and | |||
* PCI or USB connection | |||
A more detailed list of installed drivers can be obtained by entering: | |||
mhwd -l -d | |||
A detailed list will provide the following information: | |||
* Name | * Name | ||
* Version | * Version | ||
* 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 | |||

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 | |||
== Removing Installed Drivers == | |||
{{warning|use this command with care!}} | {{warning|use this command with care!}} | ||
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] | ||
