[ale] X headaches (literally)

[Dow Hurst]

Since you have the Geforce 4 Go chip, you can use the Nvidia driver to
have different vertical refresh rates for each screen.  Both screens can
be used at the same time so you can have a very large useful desktop. 
Your 19"CRT ought to have a vertical refresh between 72Hz and 90Hz to
stop the flicker.  60Hz just kills me.  Drives me bonkers.  The displays
will sometime seem dimmer at the lower refresh rate too.  I like 75 or
76 Hz.  I posted an X config example for the Nvidia card I have just
last week.  Just make sure your LCD and CRT are defined correctly in the
XF86Config file.  Hope this helps too,
Dow

John,
  You might check the refresh rate for the signal you are sending
out to the CRT. Anything less than 60 will give you a headache
in a hurry. Laptop screens have much more persistent phosphors 
(or whatever technology they actually use) and look just fine
with MUCH slower refresh rates. If possible, try to set the video
signal to a horizontal rate >80 -- if your CRT monitor will handle
that fast a refresh rate.
