Hi Adam,

    Does damage extension have the api to notify if the framebuffer has already been updated with the data? Need something to notify me if buffer has already been updated and ready for display so I can send the data to the actual physical display device.

Thanks and best regards,

  Subject: Frame buffer Changed Event.

  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,
