Dell E7440, Ubuntu 14.04 with latest updates (as of 6/11). The touchpad works fine normally, but when holding down a key (e.g. Ctrl, Shift, Alt, A, C, ...) and keeping the finger still on the touchpad, the mouse cursor jumping randomly up and down around its original location (within about 100 pixels most of the time, vertically only). Had the hardware replaced by Dell (mainboard, keyboard, and touchpad), problem is still there but less severe (only happen after some usage time, and the cursor jumping only within a few pixels).
Another symptom is application get closed randomly while I was just moving the mouse cursor around using the touchpad. I always have tap-to- click disabled, so I'm not sure how this happened. But everytime it happens, I see these messages in dmesg: [38200.256430] psmouse serio1: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [38200.257417] psmouse serio1: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [38200.258472] psmouse serio1: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [38200.261540] psmouse serio1: GlidePoint at isa0060/serio1/input0 - driver resynced.

The touchpad is recognised as a "AlpsPS/2 ALPS DualPoint TouchPad". This is occurring with Ubuntu 13.10, though I have also seen this behaviour in the version of Linux Mint based on Ubuntu 13.04.
