[mgp-users 00927] Re: Problems embedding apps in presentations

[Grunde L|voll <grunde.lovoll@fys.uio.no>]

This donsn't work on my system. When I try I get the message:

 gres>
 gres> xmgp -t 100 sample.mgp
 Xlib: connection to ":1.0" refused by server
 Xlib: No protocol specified
 Can't open display
 X(1185): Operation not permitted
 gres>

Does the script have to run as root or is there something wrong with the
configuration of my X-server?
