Switching Proprietary Drivers
How do I switch to a recommended proprietary driver on Ubuntu 12.04?
To change to the recommended proprietary driver used by Ubuntu, do the following:
- Open Additional Drivers either through Systems Settings or by clicking the Unity dash icon and entering "additional drivers".
- From the list of available drivers, select the proprietary driver requested by Steam. Your current driver is indicated by a green symbol. If the recommended driver is not listed, you will need to update your package cache by clicking the Update button.
- Click the Activate button.
- Click the Close button.
The new driver is then installed and activated. Restart your machine (click the gear icon in the upper-right corner and select Shut Down) to start using the new driver.
