Vertical retrace syncing with X

[Mike Hearn]

Hi,

This list is the wrong one, you want either the xorg list or lkml.

Having said that, I think the problem with vertical retrace is that the 
information isn't available to the X server either: the kernel needs to 
expose the event, perhaps by letting apps block on a file descriptor 
until the vertical retrace interval begins. So maybe you should talk to 
the kernel people?
