    ATI Radeon HD 4650

    Hi all,

    I'm having a problem. I have a 1GB ATI Radeon HD 4650 in my laptop. After installing the proprietary driver for this VGA Card, the laptop only recognizes 256 MB of the VGA. How can I make use of my entire 1GB?

    Below is the result of the command " lspci -v | less"

    Good question here are a couple of website that you can read about.

    Basically that command doesn't represent what your GPU is actually using. This seems to be the case when using the manufactures software.
