linux - Raspberry Pi javaFx Displaylink framebuffer -


I want to use my Raspberry P with a Java GUX on a USB displaylink display. I make my own kernel, which supports the displaylink framebuffer. When I start Raspberry, the display framebuffer becomes FB1 and the output of the JavaFX program is at FB0. How can I set the output of the javaFx program to the displaylink device? What is any other solution than copying the contents of FB1 from FB1? The X server has the option to start with the FB1 "FRAMEBUFFER = / dev / fb1 startx", there is only such a possible javaFx.

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module!
