Hi, I also don't like these: help me - I don't know how to do it postings, but maybe someone helps me to overcome my newbieness. I'm coding a kernel driver for a VIA PLE 133, which is a Trident Core. At the moment I'm trying to figure out, how the backend scaler works. I use the code example of the Xserver. One question is still left: If the adapter overlays an image from offscreen memory, which is rectangular, how the clipping is done ? How can I tell the hardware, when the visible framebuffer is shown and when a piece of the overlay is shown ? TIA, Franz
