I should have noticed something else odd about your message.  The "max 
grey level 196" is not normal at all and states that you have in some 
way select an 8-bit PseudoColor visual rather than a 24- or 32-bit 
TrueColor visual in the X windows.  Did you specifically request that in 
your .Xdefaults file?  I cannot get my X windows to do 8 bit - it has 32 
visuals all 24-bit TrueColor - say xdpyinfo to see what is offered on 
your machine.
