Hi --
I'm not able to switch to colormode float on my GRASS setup, which is a
recent CVS build running under Yellow Dog Linux on an iMac DV (Rage 128
video card, using XFree86 4.0). Here's a relevant snippet from the
commands:
GRASS 5.0beta10 > d.mon start=x0
using default visual which is TrueColor
Visual is read-only or using a private colormap
ncolors: 32768
allocating memory...
Graphics driver [x0] started
Mapset <allan> in Location <califutm10>
GRASS 5.0beta10 > d.colormode mode=float
Sorry, floating color table not available on this device
Mapset <allan> in Location <califutm10>
GRASS 5.0beta10 >
Does anybody have any insights or fixes that will enable me to use a
floating color table?
Many thanks,

Hi Allan,
as the GRASS 5 XDRIVER support much more colors than the old 4.x
Xdriver the d.colormode mode=float is not required any more. We
should consider to remove it (or improve the error message).
If you want more than 32768 colors, use the
nlev Number of color levels for each R/G/B
option of d.mon.
Hope this helps

I don't think the number of color levels is the issue (I have no problem
with running under 24-bit color). Rather, d.colormode mode=float seems
still to be needed in order to adjust a color table interactively in
d.colors (i.e. highlighting a category, and having changes to the color
table appear immediately).
