@Christopher M. Penalver (penalvch) Yes, you are right of course it WORKAROUND
The model is:
DMI: FUJITSU LIFEBOOK S935/FJNB284, BIOS Version 1.09 12/25/2014
touchpad: input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input5
This problem was on my laptop from version 15.04, earlier versions I did not install.
Now I upgrade to 16.04 but do not know whether there is a problem, because the parameters still in /etc/default/grub
GRUB_CMDLINE_LINUX="i8042.notimeout i8042.nomux"
