Short overview
Update XGetMainDisplay to avoid receiving Invalid MIT-MAGIC-COOKIE-1 key

Detailed description
The root cause of this problem is XGetMainDisplay trying to initially open display :0.0 which is not guaranteed to work.
A solution to this could be to keep the display name configurable but to default to $DISPLAY.

See https://tronche.com/gui/x/xlib/display/opening.html for reference.
