If both images are clear, then it soounds like you are using a setting
the video chip set can not handle. Possible you are configured for more
video memory then you actualy have, or you are using a video clock rate
the chipset doesn't support? One thing about X - it will try and run
configuration the hardware doesn't support. With older monitors, you
can even burn out the monitor with the wrong settings...
I would try dripping ether the number of colors, or dropping to 800 x
600 and see if that helps. (8 bit color instead of 16 bit...)
