    ATI Radeon 5470 with Natty


    I have a problem with my new laptop. I have a dual card, one is intel integrated and the second one is dedicated ATI Radeon 5470.

    Some times when I try to boot Ubuntu Natty 11.04 . The system fail to boot and I got several error messages related to the the Radeon card (at least that what I think)

    In addition if I switch to command line by pressing Ctrl+Alt+ F1 I found the following message:

    max pwm is zero

    This problem do not happen with Ubuntu 10.10

    Now this not always happen some time I can boot.

    Attached an image for the error message that I got.

    What i want to know is my card is broken (physically)? or it is only a software problem or incompatibility?

    Note: I am using the Open source driver that come with Ubuntu

    Re: ATI Radeon 5470 with Natty

    i have the same problem, i have switchable card (ati 5470 and intel)
    i use the catalist driver,

    ubuntu start but isn't stable, for example if i move an icon in docky ubuntu crash and restart the gui interface, sometime i get the same screen as you show in the picture you attached....
    another thing is the heating....

    now i'm on windows hope to find a solution but i can't find one

    i don't think is hrdware, infact in windows all work perfect

    if you have news let me know
