Restricted drivers

Some devices attached to your computer may need restricted drivers to be installed in order to work properly.

Why are some drivers restricted?

Restricted drivers are drivers for your hardware which are not freely available or open-source.

Most of the devices (hardware) attached to your computer should function properly in Ubuntu. These devices are likely to have unrestricted drivers, which means that the drivers can be modified by the Ubuntu developers and problems with them can be fixed.

Some hardware does not have unrestricted drivers, usually because the hardware manufacturer has not released details of their hardware which would make it possible to create such a driver. These devices may have limited functionality or may not work at all.

If a restricted driver is available for a certain device, you can install it in order to allow your device to function properly, or to add new features. For example, installing a restricted driver for certain graphics cards may allow you to use more advanced visual effects.

Some computers may not have any devices which can use restricted drivers, either because all of the devices are fully supported by unrestricted drivers or because no restricted drivers are yet available for the device.

[Caution]

Restricted drivers are often maintained by the hardware manufacturer, and so cannot be modified by Ubuntu developers if there is a problem.
