[X2Go-User] Keyboard doesn't work from Mac OSX to Scientific Linux 7 x2go server

[James M. Pulver]

I apologize for being a little vague and using the wrong terms. (For 
reasons I can't explain, I'm the intermediary for this report - I don't 
personally use MacOSX)

We have tested with client versions from 4.0.0 to 4.1.1 with the same 
issue, and it's that the keyboard types in "random" keys when users try 
and type anything. The clipboard seems to work properly though. Per an 
offline e-mail, we were also asked to run setxkbmap -query -v 7

results:
[dabtest at lnx100 ~]$ setxkbmap -query -v 7
Applied rules from xorg:
rules:      xorg
model:      null
layout:     us
Trying to build keymap using the following components:
keycodes:   xfree86+aliases(qwerty)
types:      complete
compat:     complete
symbols:    pc+us
geometry:   pc(pc104)
rules:      xorg
model:      null
