The man page for gamcal says:

   "Normally the gamma of the display should be set to
    2.4 using the program /usr/sbin/gamma."

However, the following lines are found in /usr/lib/X11/xdm:

   Xlogin:glGammaDefault="1.7"
   Xstartup:glGammaDefault="1.7"

NOTE: These files (Xlogin and Xstartup) do not seem to be setting the gamma
      anyway but that is a separate issue.


Using the gamcal program to help calibrate the gamma leads me to believe
that 2.4 is the "correct" value.

I am running IRIX 4.0.5 on a 4D/35.  Is there a reason for the two
different gamma values found on my system?
