I have a Dell Latitude E7240 with the same problem of erratic mouse
"jumps" and clicks, reported in the logs as:
psmouse serio1: GlidePoint at isa0060/serio1/input0 lost sync at byte 1
psmouse serio1: GlidePoint at isa0060/serio1/input0 - driver resynced.
I tried booting with i8042.reset, which did not help.
However, the odd thing is that I plugged in a USB mouse and, after
having removed it, the 'mouse jumps' behaviour stopped. I've also lost
two-finger scrolling.
The plugged-in mouse was:
input: Microsoft Microsoft® 2.4GHz Transceiver v5.0 as
/devices/pci0000:00/0000:00:14.0/usb1/1-2/
1-2:1.0/0003:045E:074F.0003/input/input21
hid-generic 0003:045E:074F.0003: input,hidraw2: USB HID v1.11 Mouse [Microsoft
Microsoft® 2.4GHz
Transceiver v5.0] on usb-0000:00:14.0-2/input0
synclient returns:
VertTwoFingerScroll = 1
Notice that the mouse wheel scrolling was also very erratic, but it was
an old device and it might have been broken. Anyhow, this makes me think
the "lost sync" problem might be related to some sort of "multi-touch"
situation where one finger on the trackpad is wrongly interpreted as two
and odd behaviour follows.
