Well, it depends on what your DISPLAY is.

Typically it is :0.0 for a single monitor on a system.

If you are using something like VNC it could be :1.0 or even a :2.0.

Once exported, your DISPLAY environment variable should not change.

did you set it in your .profile? Also check it using

echo $DISPLAY

to see current value.

Hi,
we set our DISPLAY via .profile:
DISPLAY=`who -Rm|cut -f2 -d"("|cut -f1 -d")"`:0.0;
export DISPLAY

Whenever you connect to an HPUX system (or many other UNIX systems) you can issue the command 'who -um'. The last field will be your IP address or hostname (if you have name/IP resolution)

If you are connecting from a PC that has DHCP and the IP of your PC changes then you will have different DISPLAY values.
