    Ubuntu doesn't recognize my AMD graphics

    I'm using Ubuntu 12.10. My laptop has an AMD 3100 graphics. When I go to software sources, it has nothing. What can I do so that Ubuntu recognizes my graphics card.

    when I do lspci on the terminal, I can see my graphics card.
    Here is the output:

    Do you have additional drivers activated for your graphics card? (System settings>Hardware Additional Drivers)

    AMD/ATI has moved support for the driver for all HD 1000 to HD 4000 series cards to a legacy branch. The drivers will not work with X Server 1.13, which is used by Ubuntu 12.10. Thus, you will not find a driver offered by Quantal for your card.

    The most recent version of Ubuntu for which a proprietary driver will support your card is 12.04.

    You have three options, in the order I would recommend them:

    1. Continue to use the open source Radeon driver (the default) and install Jupiter to control power consumption (and the heat associated) and to extend battery life. The Radeon driver will fulfill the needs of the vast majority of users.

    2. Downgrade to 12.04 and use the legacy driver, since it will work.

    3. Break 12.10 by following several sites' instructions for downgrading X Server to 1.12 and using the proprietary legacy driver.

    I strongly recommend against the last, although that suggestion will probably be presented in this thread. It effectively breaks and hobbles your OS and the consequences of doing so may be catastrophic at some point in the future if you upgrade you version of Ubuntu to one that uses an even newer version of X Server.

    Not sure what you would expect to find in Software Sources related to this.

    If you're not happy with the current driver you could, as suggested, install 12.04 LTS. Supported til 2017 rather than for the next 18 months anyhow.

    Ok thank you. I didn't know AMD did that. Will probably go with your first suggestion. thank you again.
