In addition to this, it is worth mentioning that with all newer systems 
and installs ,
when using lightdm instead of gdm , creating shot.sh like this:

echo 'DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 xwd -root' 
 >/tmp/shot.sh

Since it is unlikely there would be gdm use in the future OI installs, 
and lightdm used instead,
this might prove useful to someone searching for an Xorg screenshot 
solution form ssh.
