Question: But will it work with Linux?
Answer: No. [2012-12-28] It does not; it does not “work on Linux.” It might, but it does not “just work” on Fedora 17. You get a green screen, but nothing else (nothing in randr, nothing in /var/log/messages. There is folklore that if you turn off kernel modesetting then something good happens. This device still does not “work on Linux.” Without further hacking, tricking or development.

- Linux kernel 3.4.0 is the first to include a new driver for DisplayLink-based USB 2.0 devices.
- Something about problems with kernel 3.4.0 and the wrong driver being loaded; a remediation is proposed.
echo "blacklist udl" | sudo tee --append /etc/modprobe.d/udlfb.conf sudo depmod -a sudo dracut -f /boot/initramfs-$(uname -r).img $(uname -r)
- Driver is udl
- udl is a port of the udlfb driver to Linux’s DRM architecture
- David Airlie is doing this work.
- Lots of other comments recite kernel panics and other remediations for Fedora 17 and the kernel 3.4.x series
