This  program is tested in 1080p screen panning 4300x2620,
so main X server bitmap containing nested server graphic units is
4300x2620
xrandr command:
xrandr --output HDMI1 --mode 1920x1080 --panning 4300x2620

This program run in Linux Operating System initialized reaching run level 4.
This run fine if isn't nested to any user operating method layer pack of software.
This program isn't tested over X server main bitmap running as window of host
operating system [like host - window (as graphic "hole" of host O.S.) - 
virtual machine or other sometimes named "sub-system"].
With asterisk and your pointer device, in standard output over X server bitmap, you can

$ DISPLAY=:0 xterm &
----
Quick start for this program (# as root, $ as user):
From a terminal (having reached run level 4)
# X :0
From another terminal
$ DISPLAY=:0 xterm -e '/yourpath/openSUSE_Tumbleweed-Desktop-Release/CalDo/CalDo' &
