I would like to display an endless 768 pixel high image on a 1024x768 24-32 bpp monitor. The image would be scrolled 25-50 times/s to produce smooth scrolling from right to left of the monitor with new image data coming in at the right side. I assume that this is impossible using standard X windows and that I need svgalib or DGA extension. In svgalib there is a function vga_setdisplaystart() that seems to do the hardware scrlling (like virtual desktop in X servers). Is there something like this in DGA? Where can I find DGA descriptions? Jonas
