Colin Taylor, thank you for reporting this and helping make Ubuntu better.
Could you please test the latest upstream kernel available from the very top
line at the top of the page (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
kernel, please comment on which kernel version specifically you tested. If this
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested exactly
shown as:
kernel-fixed-upstream-3.17.1
This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
** Description changed:
The touchpad repetitively gets out of sync, causing the mouse to jump
around and randomly click things:
[ 399.788431] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0
lost sync at byte 6
[ 399.798582] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 -
driver resynced.
- Loading the psmouse driver with proto=exps largely avoids the problem,
- but has the side effect of merging the trackpad and the nub together as
- one input device (so you can't disable the trackpad and just use the
- nub).
+ WORKAROUND: Loading the psmouse driver with proto=exps largely avoids
+ the problem, but has the side effect of merging the trackpad and the nub
+ together as one input device (so you can't disable the trackpad and just
+ use the nub).
- Setting resetafter on the driver does fix the random moving and
+ Setting reset after on the driver does fix the random moving and
clicking, but causes the CPU to thrash as it constantly disconnects and
reconnects to try to "resync."

- I'm running dell BIOS A10 for this system, in UEFI mode.
