Default VDPAU flicker is back

Running 185.18.36 I got the flicker from
http://www.nvnews.net/vbulletin/showthread.php?t=136062
back.

I have identified that it occurs when:
- I have two screens in xorg.conf
- My secondary screen is disconnected (cable is not connected)

otherwise it works ok.

In the attachment I have:
- my xorg.conf
- Xorg.0.log.ok which is Xorg.0.log when no flickering
- Xorg.0.log.flickering which is Xorg.0.log when it flickers

Can you please try 190.36 and see if the problem occurs in that release? Thanks.

Just to clarify the repro steps: If I take your attached xorg.conf and use it, I should get the problem. Also, if I do either or both of:

a) Plug in the second display before starting X.
b) Comment out the 2nd screen definition, and remove it from ServerLayout, and restart X.

Then either of those will solve/prevent the issue?

Please can you also provide an "nvidia bug report" for the affected system; in the other thread you referenced, you mentioned you have both an FX1700 and an NVS 290, so I'm not sure which this issue applies to.

Same problem with 190.36

Steps:
- both screens plugged in - it works ok
- remove cable to second screen (CRT), restart X, flickers when playing movie with vdpau
- plug in cable again, restart X, works ok
- remove cable to second screen, restart X, flickers
- etc.

Its the NVS 290. Bug report attached

Thanks. Can you also try an xorg.conf with the 2nd screen commented out. I assume there's no problem then, irrespective of whether the 2nd monitor is attached or not?

I have tested, and then I get flicker all the time.

Commenting out different parts of my xorg.conf shows that it is:
Option "DynamicTwinView" "False"

which is the problem. When I comment this out, I get no flicker at all. It no longer matters if cable is attached or not.

So it is apparently turning of DynamicTwinView that vdpau cannot handle.
I added this to get more correct refresh rate reports from Xrandr (if I remember correctly).
