    AMD unsupported hardware, Radeon HD 6450

    Hello everybody

    I have just installed ubuntu 13.04 and everything was fine until I installed graph drivers, because after reboot I got such a watermark in right-bottom corner: AMD unsupported hardware, just like this:

    http://i.img.itunix.eu/2131353-1313775254.jpg (it's not my photo)

    So I have searched for problem solution, but most tutorials I found in google were made for old ubuntu versions and didn't work for me (or I couldn't make them work )

    Can anyone help me with this problem?

    P.S. I'm using AMD radeon hd 6450

    Re: AMD unsupported hardware, Radeon HD 6450

    I've done everything as it says in tutorial (with the latest 13.3 drivers), but I don't have /ect/ati/signature folder nor even /ect/ati/ folder, so I can't save this signature code. What to do?


    *Sorry, I have found it but still I don't know how to open signature.save file to check if it is unsigned

    gksu gedit /etc/ati/signature

    copy signature code to that file, save and restart session.

    One more question. This signature is in the 12.11 drivers installation tutorial. Will it also work for drivers 13.3?

    And what finally should be in the signature file? Only signarure code, or signature code and "UNSIGNED"? (It may be a silly question, but I just want to be perfectly sure)

    Re: AMD unsupported hardware, Radeon HD 6450

    There are two possible watermarks:
    1) Not supported
    2) Testing use only

    To fix the "testing" watermark you can replace the signature file (/etc/ati/signature) with one from a full driver release, for example that from 13.1 attached in post 79 of the "fglrx in raring" thread: http://ubuntuforums.org/attachment.p...2&d=1359650532

    Essentially, each full driver release is given a release signature. Unreleased drivers, betas, etc. are "UNSIGNED", which triggers the "testing" watermark.

    To fix the "unsupported" watermark you need to replace the /etc/ati/control file with one from a previous release that officially supports your hardware. You can download the previous fglrx package from Launchpad, for example, and extract just that control file using file-roller (Archives?). Otherwise you can try the Xorg Edgers version (https://launchpad.net/~xorg-edgers/+archive/ppa ; I wouldn't add that repository if you're not confident with ppa-purge, but I've found it to be fairly robust up until now).
    1) Dell Studio 1749: i5 540 (2.5GHz), 8GB, ATi 5650, Intel 5300AGN XFCE@Manjaro-x64
    2) Lenovo X61: C2D T7200, 2GB, Intel HDA, iwlwifi, XFCE@Manjaro-x64
    3) Compaq Mini 311c: Atom N270 (OC@2.0GHz), 3GB, Nvidia ION, Broadcom G+BT XFCE@13.10x32
