    Skipping key strokes or freezing touch pad

    One of my laptops has this odd problem - When I boot up (or resume), the keyboard acts like it's only getting 3 out of 4 keystrokes unless I type very s l o w l y. To make it more odd, I also have a non-KDE (gasp!) Ubuntu-based distro, Bodhi Linux, installed and this problem does not occur.

    dmesg reveals:

    Code:
    [ 2288.007386] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1
    [ 2288.010329] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1
    [ 2288.527071] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1
    [ 2288.530095] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1
    [ 2289.039801] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 1
    [ 2289.039809] psmouse.c: issuing reconnect request
    repeated ad infinitum. Google a bit and yadda, yadda, yadda - turns out it's a mouse/touchpad/kernel driver issue that has sort of been around in various forms for 5 years or so. Here's my issue

    http://lists.debian.org/debian-kerne.../msg00284.html
    https://bugzilla.kernel.org/show_bug.cgi?id=37852

    The work-around is to remove and re-inset the mouse driver thusly:

    Code:
    modprobe -r psmouse && modprobe psmouse
    dmesg after above command:
    Code:
    [ 2306.174322] Synaptics Touchpad, model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd04733/0xa40000/0xa0000
    [ 2306.214585] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input16
    [ 2659.700493] exe (5600): /proc/5600/oom_adj is deprecated, please use /proc/5600/oom_score_adj instead.
    Since it happens at both start up and after suspend/resume, is there one place best to put the above command? rc.local works for startup but what files are touched during log-in and startup and after suspend?

    I guess I can put it multiple places...

    Have you reviewed your BIOS settings? Are you using a PS/2 keyboard/mouse? If 'yes', then look for a 'Legacy' option in the BIOS.

      Well, since this didn't happen on the two other distros and windows 7 I have installed, I didn't dig into the BIOS at all.

      This also was occurring with only the touchpad and the built-in keyboard (it's a laptop).

      I do have a wireless bluetooth external mouse but the problem occurred with or without it synced.

        Hi all...

        "Legacy."

        My, how time and technology flies. I've recently had the pleasure of working on a system that had no PS/2 ports, just USB.
