DisplayLink USB 3.0 Support Sounds Like A Mess
While DisplayLink's USB2-based graphics adapters tend to be well supported under Linux even with a DRM/KMS driver, there's been no support for the newer DisplayLink USB 3.0 devices.
David Airlie at Red Hat spent today looking at DisplayLink USB 3.0 support and froum the sounds of it, it's going to be a mess to support without some official documentation or development support.
The DisplayLink USB 3.0 protocol is based on the notorious HDCP protocol (High-bandwidth Digital Content Protection). David started looking at how the initial packet handshake goes and while he's written some initial code, so far nothing is really working.
