Hi Doctor, First of all thanks for answering.

So you mean "video overlay" is not the same as "overlay", right? Then what is 'Option "Overlay"' (having a 8bit over 24bit) for? Sorry I'm a bit confused. Xvinfo shows expected output. Thank. >> 3. How do I tell if X is running at 24bit or 32bit colour? (on G400 32bit is >> faster than 24bit, isn't it?) >In overlay mode you must have a 32bit framebuffer. >On my machine > grep "pixmap format" /var/log/XFree86.0.log >gives > (--) Depth 24 pixmap format is 32 bpp >which tells me I'm using a 32bit framebuffer. Thanks for that! I didn't notice it. >> 5. Is there a way to change colour depth on the fly? Like Ctrl-Alt-+ to >> change resolution.

(at least for me) Thank you very much, Doctor! And, may I personally email you regarding PhD in the University of Cambridge?
