[X2Go-User] XInput 1.3 vs 1.4 Workarounds?

[Brent Roman]

After updating to Debian Stretch, I see the following error when 
starting a new desktop XFCE session:

(xfsettingsd:11973): xfsettingsd-CRITICAL **: Your XI is too old (1.3) 
version 1.4 is required.

I'm guessing this means that the emulation of xinput X2Go provides is 
for version 1.3,
but XFCE 4.12 requires xinput >= 1.4
Is this correct?

The session starts and is usable, but it locks the screen every 20 seconds.
I run lightdm with a 20 second DPMS timeout.
Normally, the DPMS timeout is increased to 600 seconds when the session 
starts, but...

xset -q reports:

DPMS (Energy Star):
   Display is not capable of DPMS

It seems that I cannot change the underlying Xserver's DPMS parameters.

Is this related to the XI too old error above?

Can anyone recommend a workaround until 3.60 is released with support 
for xinput 1.4?

Thanks in Advance,
