Hi Jamey, Thank you very much for your reply!
Have you noticed Kristian's Wayland project? In an email discussion, Kristian mentioned the "Xorg on Xorg" idea and discussed its design and implementation. Quoted from the email: "I imagine a new module called 'hosted' that lets the DDX drivers detect that they're running under an existing display server (Xorg or wayland) and then use that instead of KMS for modesetting and allocating front buffers. Ideally this can be done in a way so that the DDX driver doesn't need to know what the host display server is, but just interfaces with the 'hosted' module. Then there will be a little bit of code that each DDX driver needs to add that talks to the 'hosted' module to get the DRM fd, to set the front buffer and to post damage." Is it the "Xephyr-like video driver for Xorg DDX" you are going to achieve? I will learn and investigate the "Xorg on Wayland" project. From SDK developer's point of view, "Xorg on Xorg" has the same functionality of Xephyr to display the MeeGo applications. If "Xorg on Xorg" is better, I will go for it. With this said, I am still willing to maintain Xephyr if you need a maintainer here.
