There's a new setting that needs to be put into xorg.conf:

	Section "ServerFlags"
		Option "DontZap" "false"
	EndSection

Then you should be able to Ctrl+Alt+BkSpace to kill X.

I've seen such a behaviour before, because X seemed to be unable
to update the screen contents.

Regarding DPMS,

	Section "Monitor"
		Option "DPMS" "false"
	EndSection

comes into mind, as well as

	xset -dpms

in ~/.xinitrc. This should eliminate every DPMS attempt of X.

I don't think it has something to do with it, but maybe there's
some kind of interference between the system and X... It's always
wise to do testing with minimal settings applied.

You could be fine with a minimal .xinitrc and .xsession, both
chmodded +x. with this content:

~/.xinitrc
	#!/bin/sh
	xset -dpms
	xterm &
	exec twm

~/.xsession
	#!/bin/csh
	source ~/.cshrc
	exec ~/.xinitrc

The incorporation of shell settings depends on the shell you
use (C shell is the default shell).

VESA? Isn't there a driver for this card that gets automatically
detected (hahaha) by X .-configure?



In most cases, it's useful to delete all the many autodetected
screens in your xorg.conf, only leaving present what you really
have, nothing more. This should bypass every means of automatic
detection. Of course, you should know what you have. :-)

I hope it's okay when I attach an xorg.conf where these
requirements are met, it's the one I'm using at the moment.
Note that it doesn't conform to the new set of X settings
yet, because I'm still using an older X. Maybe it helps you
as a template or to get spare parts. :-)

And finally, have a look at EE lines in /var/log/Xorg.0.log
to see if any driver complains.
