d.info (or xwininfo) tells you the current settings.

set with GRASS_WIDTH and GRASS_HEIGHT environmental variables in the
shell (affects all new monitors).

resize existing monitors with d.resize.

[GRASSLIST:5574] Re: display monitor geometry

Hamish, thanks a lot for the reply, but I don't think this works for 
what I want.  I think that is the way to resize the monitor, but not 
the display manager (d.m).  I would like the original display manager 
to come up in the lower left corner of my screen instead of the middle 
by default, since the geometry (xy position) of the xdriver can not be 
set (from what I have been told).  Everytime I open grass, I need to 
resize and move the display manager before I do anything.  Also, my 
.Xdefaults isn't completely read anymore when I start up grass, so my 
xterm geometry is also not read.  Basically I would like a nice 
geometry upon startup of grass, without always needing to resize and 
move all the windows.

As for what you wrote, I don't think I understand everything exactly 
(still a UNIX dunce),
I set my GRASS_HEIGHT and GRASS_WIDTH to 90 as a test with
g.gisenv set=GRASS_HEIGHT=90

however my monitors still pop up as a 640x480 screen.

GRASS 6.0.0beta1:~ > d.info -d
dimensions: 640 480

GRASS 6.0.0beta1:~ > eval g.gisenv
GISDBASE=/Users/ianmacmillan/grass
LOCATION_NAME=utm11
MAPSET=ianmacmillan
GRASS_WIDTH=90
GRASS_HEIGHT=90
GRASS_GUI=tcltk
MONITOR=x0

maybe your window manager lets you save settings? Alt-middle click?
maybe you need to edit the tcl window code..?
(If you figure this out, it would be nice to tell the NVIZ control
window to stay at the top right corner of the screen too, instead of
jumping all over the place whenever you pick a new panel item....)

as for xterm, maybe:
ln -s ~/.Xdefaults ~/.Xresources
?

I dunno.  I expect that there is a reasonable default on both
systems.  "My Documents\GRASS" for Windows perhaps?

That's not likely to be the first thing you do.  If it is, then the
person who is sharing the data with you will be able to tell you how
to access it.

In the "from" (lambert) location run:
g.region rast=etop30  (or whatever map)
g.region -l

That will give you the lat/lon coordinates of the original map.
Use the greater extent of those settings (maybe a little bigger) 
as the region settings in the "to" (lat-lon) location.
You can do a little math to figure out the correct resolution on the
lat/lon side (meters/(1852.*60)) (or just match rows/cols +10% or so?)
???

This is the "Everybody gets taught ARCinfo, so if they find GRASS
hard, it's their teacher's fault" excuse.

"Open source constraints"?  Public domain software is open source
software.  Open Source comes under many licenses; not just the GPL.
See http://opensource.org/licenses/ .

Yes, that is my concern.  Glynn Clements has already said "your
proposal wasn't feasible.  Nothing has changed since then."

[GRASSLIST:5577] Re: display monitor geometry

Hi again, thanks for the reply, I think I understand things a little 
better now after some reading, but I still have two problems.  First, 
my .grassrc6 (I think OSX uses this instead of .grass.bashrc) file 
reads:
GISDBASE: /Users/ianmacmillan/grass
LOCATION_NAME: utm11
MAPSET: ianmacmillan
GRASS_WIDTH: 480
GRASS_HEIGHT: 480
MONITOR: x0
GRASS_GUI: tcltk

However whenever I open a raster I get a 640x480 monitor.  Just for 
sh-- and giggles I made a .grass.bashrc file as well that solely has
GRASS_WIDTH=480
GRASS_HEIGHT=480

Still no change in the monitor geometry.  I don't get it.

Problem 2:
Another window geometry problem I am unsure about involves my xterm 
window.  I am getting weird behavior between GRASS and X11.  My xterm 
normally opens with a 110x25+600+65 geometry when I open X11 for the 
first time, or a new xterm once X11 is already open.  This is the 
geometry I have specified in two files ~/.Xdefaults and ~/.Xresources.  
When I open grass6 using the icon, my xterm opens with a scrollbar and 
scroll length of 2000 (as also specified in these files), but the 
geometry is 80x25+600+65.  If I exit grass, then restart without 
restarting X11, the xterm opens with 80x25+0+20.  I don't understand 
this behavior.  It seems like there is an .xinitrc file or something

Well, the beauty with open source software is that you can

convince the developers here that things need to change...

No. 

.grassrc6 holds the last visited mapset etc (for when you restart)

.grass.bashrc contains custom start up commands 
   (when using a Bash/Bourne shell)

almost there. For the shell variables to escape their script (here
.grass.bashrc) and be passed on you need to use "export".

make the file look like this:
export GRASS_WIDTH=480
export GRASS_HEIGHT=480
