Touchpad message about hid-rmi

Touchpad message about hid-rmi

[gregory]

Kernel input hackers,

I recently got  a System76 Galaga Pro that I've been having some issues
with the touchpad on.   One of the main oddities was the following
messages:

[  784.876080] psmouse serio2: TouchPad at isa0060/serio2/input0 lost
synchronization, throwing 4 bytes away.
[  794.324013] psmouse serio2: TouchPad at isa0060/serio2/input0 lost
synchronization, throwing 4 bytes away.
[  820.126753] psmouse serio2: TouchPad at isa0060/serio2/input0 lost
synchronization, throwing 4 bytes away.
[  828.493701] psmouse serio2: TouchPad at isa0060/serio2/input0 lost
synchronization, throwing 4 bytes away

 I did notice the following message today:

[  631.408929] psmouse serio2: synaptics: Your touchpad (PNP: SYN1221
PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi
are not used, you might want to try setting
psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.k
ernel.org.
			

I'm currently running on the 4.13.3 kernel.

I set synaptics_intertouch=1 in /etc/modprobe.d/psmouse.cconf and then
did an rmmod psmouse && modprobe psmouse, which seems to have helped
with those synchronization messages.  It did trigger the following
though:
