dmesg | tail

looks like a flakey mouse to me:

[226752.422142] psmouse.c: Explorer Mouse at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.

Pretty much says it all.

try adding the boot option:

i8042.nomux=1

if you run:

gksudo gedit /etc/default/grub

and change:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux=1"

Save the new file, close gedit then reboot, it may be nicer.

Can you help with this problem?
