bash script help

[Noah John Gellner]

I am using a script to preload openoffice so that it starts more
quickly. The script works very well except that when I exit X to get to
the console the script keeps running and outputting messages to the
display reporting that no display is found. 

I am hoping that someone can tell me how to modify the script to test if
X is running, and if not to terminate the loop. 

The script comes from the Gentoo forums and has two parts

Part one is called by Gnome Sessions:

## killing all traces of openoffice
killall -9 ooresident
killall -9 soffice.bin

## waiting for them to really dissapear (can even take a sec or 2
depending
## on the busy-ness and speed of your system)
sleep 1

## the actual keepalive is called in the bg
ooresident &

Part two, called oowresident, is obviously called by part one:
#!/bin/bash
killall -9 soffice.bin ## just in case....
i=0
while [ $i -eq 0 ]
echo $i
do
{
      dummy=`ooffice -plugin -quickstart ;`
      i=$?
      echo $i
      echo "OpenOffice was unloaded. Loading it again..."
}
done
			
Beside the problem with the script not terminating with X, it works
really well, shorting OO startup times to a few seconds.

Help is greatly appreciated.

Cheers,
Noah
