[mythtv-users] judder problems with nvidia 358.16

[Alex Halovanic]

Thank you Mark.  From the log entries it just keeps coming back to that
MythTV is having parsing and matching issues between all the contradictory
XRandr and NVIDIA data. I have pretty much given up trying to figure out
what is going wrong there.

Happily, I am able to report that I have gotten the following working in a
proof of concept patch:

   1. Report all the non-integer refresh rates in the MythTV GUI accurately
   for a monitor using only XRandr.
   2. Switch to the exact modeline for that selection when playing a video

I have some follow ups to do on a couple of points (besides cleanup) before
I think this is usable:

   1. Prevent X from panning the screen around when we do switch to a lower
   resolution
      1. This should be simple, but for some strange reason seems to
      require special steps including disabling the monitor before the attempt
      under some circumstances (possibly NVIDIA related).
      2. Figure out what MythTV is doing (or should do) on the attempts to
   switch to a GUI resolution.
      1. This is reported as an attempt to switch to a refresh rate of 0.

I have also not had a chance to sync up with 0.29 yet.

Thanks,
Alex
