    Trackpad Does Not load at startup

    Hi,
    I am running Ubuntu 12.04 on a 2011 macbook air.

    I have noticed over the last month that the trackpad does not always seem to load at startup. I can log in ok, and the 'pointer' will appear on the screen, but will not respond to any touches, etc.
    To make matters more confusing, this does not happen consistently. It seems to happen approximately 1/3 of the time. When it happens, it typically requires two reboots to get the system to boot (load/start up the trackpad) properly.

    Any thoughts? I'm not sure where to look (or if I should be looking) in the log files for answers.
    Thanks,
    Nick

    After a bit more searching....would using mkinitrd be a possible fix?

    This may not be the sanest approach, but here's something I did on an old PPC laptop (Ubuntu 12.04) because the trackpad settings failed to "stick" across a reboot.
    Inside my .bashrc file, added the lines

    sudo chmod 777 /dev/adb <<endsu
    {my password}
    endsu
    trackpad tap
    trackpad drag

    And that works just fine. If you want to be more careful, you could add a couple followup lines to return /dev/adb to 511 permissions.

    Thanks for your reply. I'm not sure that this will work for me though, since /dev/adb does not seem to exist.

    Sorry -- you're correct, as only older Macs w/ ADB (Apple Desktop Bus) -based trackpads have this. But you should have a corresponding tool in /dev which the "trackpad" command accesses.
