Currently there're 2 different implementations of the driver for DisplayLink USB2.0-to-HDMI/DVI adapters: older FBDEV and modern true DRM. We initially decided to use FBDEV version just because with it /dev/fbX is usable from user-space while in DRM version with DRM_FBDEV_EMULATION user-space cannot draw anything on a real screen, for more info read [1]. But today /dev/fbX is not that important as more and more software projects switch to use of DRI (/dev/dri/cardX). But what's even more important DRM driver allows building of complicated graphics processing chains. The most important for us is rendering of 3D on a dedicated GPU while outputting video through a simpler bitstreamer like DisplayLink. So let's use much more future-proof driver from now on.
