How do i remove the title bar in the cygwin mintty terminal window ? there is no option in the options -> window configuration
You can do this only if you launch from a command line. Use
-B) followed by either
frame. For example...
mintty -B void
man mintty (which you should read) the difference is:
Suppress window title, display only a frame or no border.
void results in no border at all and
frame, yep, just a frame.
You will have to use keyboard shortcuts to move the window around, of course.
