[about having an ATI Rage Pro where the screen goes black]

your problem is mostly not video shadowing, but just that DOSEMU does
not support this video card and does not open up enough ports.

I remember talking about this before when I still used console DOSEMU.

I don't know much about the X stuff.
For the console, the problem is that "ati" refers to older ATI cards.
dosemu probably hanged while trying to initialise the video card, that's  
why you couldn't type exitemu.
Try $_chipset = "plainvga" for now. If that still doesn't work, the
following can give you a clue:

Run "dos -D+i -o /var/tmp/errors" and analyze /var/tmp/errors to see which
ports it tries to access and dosemu doesn't understand. You can enable
then in the "ports" section. Don't do this is if you're paranoid about
security though.

If it works you probably won't be able to do console switching, except to
and from X.

you could also try a development version of DOSEMU with svgalib support
compiled-in and $_chipset = "svgalib".

And then still, no guarantees, vesa modes may still be broken, the
screen can go black, your computer may hang, and you may harm yourself
and your monitor (depends a lot on the monitor though, but older
fixed-frequency types are easily damaged). Stas tried hard to get
DOSEMU working on his ATI Radeon, and Vesa modes do not work for him.
Neither do they in NT DOS boxes.
