[GRASSLIST:2266] Display problem of floating point raster data

I'm running GRASS5 compiled from the CVS sources (24.07.) quite
smoothly on different PC's using different linux distributions (Redhat,
SuSE, 'LinuxFromScratch').

On one PC I experience a display problem (on the others I use the
same data, but have no display problems):
I can't display floating point raster data, whereas integer raster data show up with no problems.
The compilation of GRASS didn't give me any error, so I don't assume
that its really a GRASS problem, but more some kind of configuration
The floating point data are calulated by r.mapcalc on that machine, I can calculate r.support, stats and so on, thus the data seem to be ok.
seem to be ok.

I start the display as usual: "d.mon start=x0" and get
"using default visual which is TrueColor
ncolors: 16777216"

Xserver configuration:
XFREE 3.3.6 11.0
24 bit
Windowmanager: KDE2
SuSE 7.1
(Hardware: Matrox Millenium II, Compaq Pentium 200MMX)

Should I run the server on 16 instead of 24 bit?
Any suggestions?

Thanks in advance,
