[AG-TECH] VPCScreen and Keynote

[Andrew Rowley]

Hi,

I believe the problem with this and VPCScreen is that KeyNote uses hardware acceleration to display the presentation.  This means that although you see the image on the screen, software screen captures will not as the image doesn't exist within the operating system screen buffers.  

The only way to avoid this is to disable hardware acceleration either within the operating system or within KeyNote itself (I have no idea if this is possible in either Mac or KeyNote).

I actually ran into this issue today using Keynote and Vine Server.

The screen resolution was set to the same and I couldn't find a working 
solution other than to export to Powerpoint.

I do see the Vine Server release notes 
(http://www.testplant.com/documentation/Vine%20Server%20Release%20Notes.pdf) 
indicate as something 'still to do':

Add "Send Full Screen" Mode - Useful for things like Keynote which 
bypasses CGRemoteOperations API
Possibly Detect when machine enters such a mode - ie starts running Keynote

Not sure if anyone has any other work around, but other suggestions 
would be great.,


Todd

Many screen capturing tools have this issue with fullscreen Keynote.
