HI.
DirectFB using the current Linux-A20 will be configured from the GUI.
However, only one layer is made in creating a Layer DirectFB.
Below is a debug message when running the arm-linux-dfbinfo's provided in directFB.

When I tried to get the Layer again after obtaining the Primary layer results in an error as shown below.
