Hi Shawn, I've just put some more pieces into the kernel. https://svnweb.freebsd.org/changeset/base/279752 https://svnweb.freebsd.org/changeset/base/279753 Can you give the current code a spin? To get X.org/X11 working simply create a config file under /usr/local/etc/X11/xorg.conf.d which contains the device section given by "man xf86-video-scfb". Open issues: - Restoring the frame buffer does not always work. I looks like the restored text console size is 1x1 afterwards. At least there is no panic. And you can re-plug the UDL device again. - You need to unplug the UDL device before rebooting. - UDL device must be connected to a monitor before you plug it to USB, or you can load/unload the driver to re-probe the video format. --HPS
