DisplayLink Forum - View Single Post - Using framebuffer with AOC E1649FWU monitor on Ubuntu 14.04

I am trying to use an AOC E1649FWU monitor on a system running Ubuntu 14.04.3 LTS (64-bit). The monitor is recognized and after installing the latest DisplayLink drivers, the backlight comes on, but I cannot get anything to be displayed on the monitor. I am not running X on the system and would like to just use the framebuffer to display things on the monitor. I see that a framebuffer device is created /dev/fb1 (and sometimes /dev/fb2, it seems to always create a new device) but writing to it does not seem to do anything. The monitor just remains black with the backlight on.

Most people seem to be concerned with getting X to run, but I would rather avoid using X if I can. Anyone get a DisplayLink monitor working with the framebuffer?
