Hi, I am a new user of Xorg and Compiz! I am working on a proof-of-concept software in X and My setup is: Intel 965GM, FC11, Intel video driver 2.7.0, Kernel 2.6.30. I have already made changes on DDX to get the damage data from damage extension and I want to validate the damage data by displaying a black rectangle about the size of damaged area on the screen and slowly fade it over time. This is an intermediate step which will be very useful in the later stages of my development. I am hoping to get some direction from the list on a. if this is possible at all, b. if possible, what are the modules of interest in Server/extensions that I will have to browse through. My preliminary analysis points me towards Composite extension. But I am getting the damage data in DDX and I am not sure if I could send damage data from DDX to Composite extension. I regret for the open ended question and any information or pointers will be helpful. Thanks. Reg, Siva
