Unwanted cursor with Java2D drawing directly to framebuffer

Question

The environment is Java 11 on a Raspberry Pi 3B+ with a 3.5" touchscreen. The program writes directly to the framebuffer with the aid of Thomas Welsch's JavaFrameBuffer JNI support.

Things work as expected, except that a blinking cursor appears on the screen after drawing some text. This app uses no input except screen touches, so a cursor is irrelevant and visually disturbing.

How can I get rid of it?

Please note that no Component is present, so there is no setCursor method available.

Answer 1

The problem is that the lack of a component prohibits the easiest way of hiding the cursor with setCursor.

I tried the following in the cmdline.txt:

vt.global_cursor_default=0

(do not forget to reboot ^^)
