Hi Bob,
Thank you for the reply.
We are using Grid computing, so need to pass DISPLAY variable to other
Unix and Linux.
And we are using Solaris 10 gnome and KDE environment.
We have tried to cange Xservers file in /etc/dt/config/
however it seems to work for only Console session.
any other way to simply change DISPLAY variable for all csh, ksh, bash
in Gnome and KDE environment??
Many Thanks,
