Side question, for those who use Teamviewer with no monitor, is there a way to adjust the resolution? I can't even view the entire tab for display options because the resolution is so low. Thanks
Also experiencing this problem when using VNC viewer.

insert in 1bash before TEAMVIEWER="NO" # YES NO
this:
xrandr --fb 1024x768 (or whatever resolution do you need)
works for both Teamviwer and VNC
