So, you plug in your device, play with RandR to get it displaying bits from the window system and then carefully configure your VR application to use the whole monitor area and hope that the desktop will actually grant you the boon of page flipping so that you will get reasonable performance and maybe not even experience tearing. Results so far have been mixed, and depend on a lot of pieces working in ways that aren't exactly how they were designed to work. His blog has some recent updates.
