There is no text mode - the adapter only understands pixels. Instead
you need to advance your basic graphics to render text in the font of
your choice. Or see udlfb in your preferred Linux kernel distribution
(or udl in your preferred OpenBSD distribution) to treat the
DisplayLink screen as a generic framebuffer and render the text with
any framebuffer aware graphics library.
