I run the script (sylph start ) from the console , as root, and no
errors.the email client started just fine.But when I tried to start with
monit , (monit start sylpheed-claws ) I cached the folllowing error :
GTK-Warning**:cannot open display : 'sylpheed-claws' failed to start . So it
seems that the problems relies when monit calls the email client through the
wrapper script ; I looked at the executable permissions and they all are the
same (run as root, in this case); also in monitrc I put the condition to run
the wrapper as uid root and gid root :

```````````````````````````````````````````````````
check process sylpheed-claws with pidfile /tmp/sylpheed.pid
   group mail
  
   start program = "/usr/bin/sylph start "
     as uid root and gid root
   stop program = "/usr/bin/sylph stop"
      as uid root and gid root
```````````````````````````````````````````````````````````
Now I really got confused.
