problems to open graphics device

Hi,

I got an error message when I tried to open GRASS monitor from a remote PC. The error
message is:

X Error of failed request: BadMatch (invalid parameter attributes)
    Major opcode of failed request: 78 (X_CreateColormap)
    Serial number of failed request: 227
    Current serial number in output stream: 228
Error - Can't set up pipe to graphics device.
Problem selecting x1. Will try once more.
Error - Can't set up pipe to graphics device.

By the way, it doesn't have that problem when I run GRASS from the SUN console. I
think I set the "xhost" correctly in my PC and I have no problem to
link to open windows/graphics from other software remotely.

I am a new user in using GRASS. Thank you much for your help.

The standard GRASS xdriver only works on 8-bit graphic displays. Check
your PC display to be sure that it is set to 256 colors. If you wish to
be able to display on a PC running more than 256 colors, you'll need to
get the contributed "24XDRIVER" code off of GRASS ftp site. This will
provide you with a GRASS 8-bit display window that will work on 24-bit
desktops. Good luck,

Hi,

My x-server for Windows runs the standard 8-bit monitor on my (24-bit)
graphics screen. This might be an easier solution than compiling the
XDRIVER24 code, as you won't need to change GRASS at all, just your PC.

The one I use is 'Micro X-Win32' for Win95/NT (around $200 from Starnet:
sales@starnet.com). You simply tell the server to do 'Pseudocolor
support in 24-bit mode' and it fools the grass 8-bit monitors into
thinking they are working on a pseudocolor display. You can get a demo
of this which runs for 2 hours at a time, to test this out. Other
x-servers (e.g. StarNet's Win3.1 version, or Vista eXceed, or the one
packaged with NT server) might do this as well now for all I know.

Just a thought.
