RM> Hey guys,
RM> I use Esetroot to set the background for my Desktop.I use openbox as

RM> the second script works just fine for me and so i am wondering why
this RM> script is not working.Is it because the script is executes an
another RM> user(thought not likely since no one else has execute
permissions on the RM> script).
your X server doesnt allow user 'rmanocha' to make direct connections to it.
thats because access control is enabled on your box. check the output of
`xhost`. should give something like:
access control enabled, only authorized clients can connect.
and, you are not authorised (the script is owned by user rmanocha, who is
probably not on the authorized user's list). check `man xhost` and do the
needful.
cron is running as root, and it will never let any script owned by an
unauthorized user to make direct x connections. thats considered dangerous.
as ams pointed out, put it in your own crontab. or add yourself to xhost (i
would probably do the latter if i am on a single user system).
regards,
bhaskar
p.s. your script uses Esetroot without the `-d` param. i dunno what
consequences it might have. do test it for multi-user environments also.
