    inspiron 15R flickering horizontal line

    I just installed Ubuntu 11.10 on Dell Inspiron 15R. Windows 7 works fine on the laptop, but with Ubuntu, there is a flickering horizontal line (4 or 5 pixels thick) at the top of the display. Not a show-stopper, but a nuisance.
    kernel is 3.0.0-23-generic-pae
    display is set at 1366x768
    gui is lightdm

    please advise

    With 12.04 LTS out a few months now, I'd just go right to that instead of using the older 11.10 and hope the newer version doesn't have your issue (which I've personally never seen). I've run 10.04 LTS on my older Dell Inspiron 1545 for years; I've also booted 11.10 and 12.04 LTS on it, no screen issues for me.
