trouble starting monitors in grass5

GRASS GRASS user

I got a problem with my new grass5 installation. When I try to start a
monitor I get the message:
" Sorry, permissions on </usr/local/grass/dev/fifo.1a> (644) should be
0666 Have GRASS administrator check etc/monitorcap file "

I can't see what's wrong with my monitorcap file

Hi,

there is nothing wrong in your monitorcap file, but the "fifos" seems
to be damaged or having wrong permissions. No problem:

1. Change the permissions as root:
   - go to grass5/dev/
   - chmod 0666 fifo*

  That's it.

If that does not help:

2. Create new fifos:
- go to grass5/dev/
- look for the fifo-creating script create_fifos.sh
  If not there (should be), get it from:
   Bereich Geographie – Naturwissenschaftliche Fakultät – Leibniz Universität Hannover

- rm fifo* (throw the old ones)
- run the script to generate new fifos:
   sh create_fifos.sh

Feel happy.

Best wishes

Gentlefolk,

  I have a problem with my new grass5 installation.

  The messages from last week about <chmod 0666> allowed the starting of
of the monitors.

  Now I can select a monitor with no messages. However, when I try to
display a vector file I get the message:

No graphics monitor has been selected for output.
Please run "d.mon" to select a graphics monitor.

  1) There is a screen x0.

  2) There are no files under the ..../grass5/locks/*/ directories.

  ???

  Many thanks.
