Hi , I want to write a driver for my graphics card in Kdrive .The graphics card has trasparent overlay support.We can use that overlay as a normal Framebuffer .I want to use this overlay to show transparent windows on it. I have gone through the DDX drivers in Kdrive , but no one has provided support for hardware overlay . How can i tell the gtk applications about this overlay, so that gkt applications can write on it ???? Thanks in Advance -Manisha
