In my case, it does not ask for the confirmation. It simply takes the
last used configuration from - extend, duplicate, projector only and
laptop only whenever I connect an external monitor or projector to my
laptop. And on my Dell laptop, Fn + F8 is the key combination for
changing display setting.

Typically the catch process for what you experienced is time. If the
external monitor blanked because of setting conflict then the
confirmation window, which would pop up, would time out after 30
seconds I believe. If you have not confirmed to keep changes then
the system would revert to the previous setting. If this did not
happen then there may be a bug. Additionally, you should have on your
laptop function keys which will cycle monitor settings. Mine is
fn+F10 on a Lenovo. The cycle should be laptop, mirror, external,
extended in most cases if memory serves.

I have had to reboot my notebook today in my lecture, because of blank
screen.
What happend?
I attached an external monitor (projector) and with
xfce4-display-settings
I selected this monitor only, instead of mirror mode. The external
monitor
was unable to handle my resolution, so it went blank and I was not
able to
reselect the internal display, because I saw nothing.
Is there a hotkey to enable the internel notebook display or to
switch the
monitors?
