[CentOS] Monitor Dummy Device

[Joey]

Thank you Jonathan for your participation.

But i only want the same workflow like a second device is wired.

A hoped its possible to configure a second xorg-server or a
fakedevice/-monitor that kde recognize this and you could use this as
second desktop in same way as in dualscreen-modus.

So i ask a lot of people the last days and ok, maybe tis solution seems
unavailable without deeper knowhow.

Thank you all.
