Radeon Drivers R9 270X Ubuntu 14.04 [duplicate]

Do I need drivers for my graphic card Radeon R9 270X? If yes how can I install them?

Solution 1:

Open the Software & Updates utility and open the Additional drivers tab.

If your graphics card is listed, like in the picture below, the proprietary drivers can be used, and you can install them from this screen with a single click, if you have Ubuntu already installed.

The installation will, however, not work on a live system, as video drivers are one of the few things which require a reboot. (And no, persistent pendrives don't work either, the installation will only work on a fully installed system.)

If the graphics card is not listed, then your graphics card is most likely not compatible with the proprietary AMD driver. If the default, open source driver works, stay with it.
