Give a try to run nrpe on remote host as daemon instead of under xinit.. 
thingy

nrpe  -c /pathTo..nrpe.cfg -d

make sure you have set the line in nrpe.cfg to allow the nagios machine 
to connection to nrpe on port 5666

#allowed_hosts=127.0.0.1,xxx.xxx.xxx.xxx


After running nrpe make sure it is running

#netstat -tuanp | grep nrpe
tcp        0      0 0.0.0.0:5666            0.0.0.0:*               
LISTEN      9583/nrpe


Then from nagios machine test again as you did it before with the same 
command.
