"One thing I have noticed while using KVM is that if you boot one

low resolution VGA monitor."

I misread your pot. Sorry about that.I was thinking that you may be 
confusing the defaults for vncserver with
a problem with the KVM. Aren't KVMs just dumb switches? If there is a 
problem with your minimal defaults in the computers X config file.
With no connection X could be cycling down to the lowest settings.

Well, actually this setting is integral to the resolution operation of
the vnc client. Each user of a remote machine may start as many
instances of vncserver on that remote machine as they like at any
resolution. The geometry is inherent in the start up of the vncserver
program, not the vnc client. The default tends to be 1024x768.

For example I use vnc in win XP to manage a bunch of linux servers.
In XP I use dual monitors at 2048x1162 with the desktop spanning both.
So, to get resolution from vnc to match my usual desktop I start
vncserver on the remote machine with:

vncserver -geometry 4096x1162 -depth 24 :1

Voila! I go to full screen mode with the vnc client and I have
an X desktop that spans both of my local monitors.

Yeah that sounds right. If you have 32x32 icons on the desktop
it doesn't matter what resolution you set the desktop to, those
icons will still be 32x32.Same with pictures.

That sounds right. Actually on some of my systems if I do that
I lock up the vncserver completely and end up sshing to the machine to
kill the server and restart it.
