Why are images imported with r.in.tif displayed in only about 4 shades of
gray when my X display is working at 16bpp and I'm using the
XDRIVER_24bit? Is there a way to get al 256 shades displayed or do I have
to go to X with 24bit ( it'd be 800x600)?
I'm trying to overlay and georeference these images to the underlying spot
and it looks very wierd
Thanks in advance
Simon.

Hi, Simon In order to display 256 gray shades you need to be running your
grass monitor in "float" colormode (d.colormode float; d.erase).
Unfortunately, the XDRIVER_24bit doesn't support this. You'll need to set
your computer display to 8-bit and run the regular 8-bit XDRIVER.
So, how's about it, folks? What GRASS desperately needs is a proper
24-bit display. My $.02.
