This is the virtual 800x600 mode, right. Physical 640x480 resolution.
If you are referring to a different mode, ignore the rest of the reply.

Yup.

The xv dialog boxes, etc. were OK for me.

Yup.

Yes. I did observe the same problem. The Mono Xserver works fine, except for
"xv" (and maybe a lot of other clients which I didn't compile and test).
The problem went away immediately, as soon as I changed to the colour Xserver
(X386), though. Now, two sources (at least) of this problem come to mind:
	1. xv is not suited for monochrome servers (which I doubt, because
	   I have it running on a monchrome SUN - the same code that is)
	2. the Xmono server has problems with certain types of clients which
	   is more likely. Although I could run the "xdl" tool just fine
	   with the mono server.

[text about working X clients, etc. deleted - NB.]

So, it's not (just) you that did something wrong (except if you changed the code
for xv - I am using version 2.21). It is more likely that the are problems in
the mono Xserver.

You should buy a 100 US$ SuperVGA board :-)
