Frame buffer Changed Event.

[Leandro Galvez]

Hi All,

    I am using Xorg on top of Linux virtual frame buffer. What type of event or hook should I use to catch events after any part of the frame buffer has been updated? I would like to catch events that would trigger right after the frame data buffer has changed so I could feed the contents of the vfb to an actual device that can display it. I would like to catch the events globally and not just in specific applications.

Thanks and best regards,
Andy
