NAME
     preallocColors -  preallocate colors to minimize desktop colormap
     flashing

SYNOPSIS
     /usr/lib/desktop/preallocColors

DESCRIPTION
     preallocColors is run early in the login process to preallocate a small
     set of colors used by the IRIX Interactive Desktop.  By preallocating
     these colors early in the login process, it avoids colormap flashing when
     running GL programs.

     On machines with multiple colormaps, where flashing is not a problem,
     preallocColors exits immediately, without allocating any colors.  On
     machines with a single colormap, preallocColors will allocate the colors,
     and for a child.  The parent will exit immediately, while the child will
     sleep for several minutes, holding the colors.  After that time, the
     child will exit.  It is assumed that the IRIX Interactive Desktop will
     start up within that time period to continue holding the colors.  Should
     startup of the Desktop be delayed, colormap flashing is possible.

     preallocColors is run from the file /usr/lib/X11/xdm/Xsession.dt at user
     login.  Users should normally not run this command directly.

     For more information about the entire IRIX Interactive Desktop
     environment, see the IID(1) man page.
