X whacking monitor

[Paul M Foster <paulf@quillandmouse.com>]

I've got a "Trident Microsystems CyberBlade/i1" video chip (according to
pci -v) on the motherboard of my PC. I don't know if this has anything
to do with the problem, but...

In running X Window version 4, when I go into X from the console, all
is fine. I can then get back out to a console. But when I go back into X
from the console (after _any_ amount of time), the screen is blank, and
after a second or two, the monitor loses its signal from the PC (it's
one of those monitors whose LEDs blink when it has no signal). Moving
the mouse or hitting a key does not solve the problem. I can
Ctrl-Alt-BackSp and get out of X.

However, this problem disappears when running version 3 of X Window
(XF86_SVGA server). Anyone run into this and know why it happens?
