Hello,

Further to the discussion in http://www.aps.anl.gov/epics/tech-talk/2011/msg00585.php, I have been trying to open edm windows at specified locations from the command line. I can't get that to work, but before that, can't seem to get the edm display file server and related operations to work.

Firstly,
edm -server
or
edm -server -display $DISPLAY
both open an instance of edm.

Subsequently:
edm -x -open file.edl
returns the error "No server found for display - abort"
This error is returned even if the -display option is included before -open

This works for me, provided that I started the server with the -display

option. If I connect in with ssh, "echo $DISPLAY" displays

"localhost:19.0" Is it possible that the DISPLAY variable is set

incorrectly? (If $DISPLAY is an empty string, then 2 copies of the edm

server would have to be loaded for -open to work).

I've tried edm versions 1.10.1w, 1.12.39 and 1.12.56.

(I'm using edm 1.12.40, but I don't think 1.12.39 is much different, it

looks as though 1.12.58 might have some relevant changes)

However, if I don't use the -display option when starting edm -server,

then I get the same error message, unless 2 copies of the edm server are

running. I suspect this is a bug in locating the edm server, as edm

-one -server will allow me to load exactly 2 copies of edm. On the

production systems, we typically run multiple servers, and use the -port

option to select the correct one when giving the -open command (rather

than -display). In either case the -display is necessary for the -server

command, but not with the -open command.
