This was actually covered in another talk on the Graphics track. Jim Gettys, also in attendance, pointed out that there has been an XSync extension for over 20 years, though XFree86/Xorg doesn't implement it. (Apparently this was introduced to support video-conferencing before there was more extensive video acceleration exposed through the XVideo extension.)

That's interesting - any idea where to get the slides from that (and other)
talk(s) from the conference?

Sorry for the almost content-less comment.

No slides, but the notes are at http://dri.freedesktop.org/wiki/CompositeSwap

Most of the slides are available on our LPC Program page already, and the videos of the keynotes (and some sessions) will be up there too as soon as we get them (hoping in a week or two). Please see our call for material and feedback on the LPC blog as well. If you were at LPC (or even if you weren't), you can send us feedback on the content of the sessions and the conferenceas a whole. We'd appreciate hearing from you!

Thanks for the links!

No, I didn't attend, but I'm really interested in the nice improvements that
are coming down the pipeline to Linux's video and audio systems, which both
have sadly long been messy and lagging far behind what's available on
competing platforms - from a pure desktop, not multi-user client/server,
perspective.
