    Gateway E295C special laptop keys under monitor not working

    I have a Gateway E295C/C140/M290. It's a tablet PC, which has its own set of challenges, but this one in particular is about the keys underneath the monitor (see attached picture).

    Ordinarily, these keys do not seem to be registered as X events using xev -- that is, no output is generated in xev when I press these keys.

    The only time they do anything at all in Linux is when I press one of the four buttons on the left of the D-pad first. Then, pressing up or down on the D-pad will mimic the behavior of Fn-up/down, which is to adjust the monitor brightness. For example, a-b-c-[Ddown]-[Dup]-1-2-3 will produce:

    I'm not sure what it means but the "serial" value only seems to increase as a result of these D-keys, and only when another key has been pressed in between presses of that D-key. For example:
    Code:
    <startup>  serial 48
    [a]        serial 51
    [b]        serial 51
    [Dup]      serial 51
    [Dup]      serial 51
    [Ddown]    serial 53
    [Dup]      serial 53
    [a]        serial 55
    [1]        serial 55
    [Dup]      serial 55
    [a]        serial 57
    I'm not sure what this means, but they only seem to be recognized if they activate as monitor brightness keys.

    What else can I do to help get these keys recognized so that I can assign functions to them?
