So, I wanted overlay, but I also decided to switch to XFree 4.0.1. So, now, thats what I have, still with the G400Max. Overlay now produces some strange results, it basically throws 3 fuzzy, mostly transparent, b&w images across my screen. Perhaps if the images were on top of each other, they would for a complete color image, I don't know. Anyways, anyone have a clue on that one? leko:~>v4l-conf v4l-conf: using X11 display :0.0 dga: version 2.0 mode: 1600x1200, depth=24, bpp=32, bpl=6400, base=0xe4000000 done -Aaron Solochek leko@xxxxxxx Ragga Muffin wrote: > Aaron Solochek <leko@xxxxxxx> wrote: > > > I was wondering what the difference between overlay and grabdisplay are, > > in terms of preformance.
