Normally when you detach from a screen session, you can use `screen -r'
to resume it.  But if the screen session has not been detached yet (that
is---a terminal is still viewing it), then `-r' will not work.  In that
case, you use `-x', which will result in two terminals viewing the same
screen session (which is what it means by "multi display mode").

For example, I may leave a screen session attached at work, but later
SSH into the machine.  Since I never detached from the session, I must
use `-x'.

I may also use this flag to demonstrate commands to other users
remotely, or open the same session in multiple VTEs on multiple
monitors to view another window in the same session on another monitor.
