    Which version of Ubuntu are you running? With a 3.10 kernel, did you upgrade the kernel yourself or are you running the development saucy version?

    Where do I file the bug report exactly?
    Open a terminal window and enter:
    Code:
    ubuntu-bug fglrx
    ...to start the process. You will need an account on launchpad to do this.

    Re: Backlight Problem with Acer Aspire V5

    I used the official Lubuntu 13.04 release and I upgraded the kernel myself in an effort to get the backlight working(It broke audio instead. :/) and I still didn't get the results I wanted. I was going to upgrade to the latest development kernel, but fglrx wouldn't play nice with it, so I had to settle for the 2nd latest.

    Thanks for the help!

    My Aspire uses the left/right keys to adjust brightness.

    Maybe this is an error and you meant to say Fn+Left/Right keys work?

    I had that problem with my new Acer Aspire One 725, and after updating the linux-headers the brightness worked.(Fn+right or left arrow keys)

    Yeah, I wasn't really paying attention to the key-bindings. More on the actual problem.

    Not for me. I already have the latest builds for.. well.. everything. Its not that I think that upgrading won't work, but I don't have anything else to upgrade. I might go down to Wal-Mart, find the same netbook and grab the recovery software to get Windows back.

    Also, I haven't asked this yet because I've been busy, but I am running the AMD proprietary version of the flgrx drivers. Should I still file a bug report against flgrx(B/c Ubuntu says that I don't have fglrx insatlled on my system)?
