24-bit TrueColor

Question

I recently reinstalled solaris 8 on my ultra 5 machine.
It seems there is something wrong with my X settings,
since my X-windows cannot deal with a large magnitude
of open windows; it will give me warning such as
Warning:
Cannot parse default background color spec
Warning: Cannot allocate colormap entry for "gray80"
Warning: Cannot allocate colormap entry for "LimeGreen"
Warning: Cannot allocate colormap entry for "gray50"
ERROR: could not allocate 20 required colors from
the default visual.
You may be able to avoid this problem in the future
if you use a 24-bit visual in your X server startup.
Try using a 24-bit TrueColor visual as the default, or
try a 24-bit DirectColor visual on HP machines.
Changing the /usr/dt/config/Xservers so that X can
handle 24-bit True color does not help. There was no
problem before reinstallment. Anyone have an idea what
could be going on?
Thanks,

Usually colormap problems are due to not having enough colors defined for your display. Most likely you are running at 256 colors. If youare running through a monitor try looking at the fbconfig program.
Insure your current Depth is not 8 bit
$ fbconfig -propt
