Stubborn app won't run over Remote X

[bcmurray75]

Hello all.
I am fighting with an application which will not display on any X than 0.0.


I've tried nomachine NX and am able to run everything. However, the performance issues on this system makes it unusable. There are slight issues with image clarity, but what is worse is there are major refresh issues along with broken fonts. A better description of the refresh issues: I'm looking at a series of images, when i movie through those images the screen stays where I started until I "force" a screen refresh by doing something like bringing down the Edit menu, then the image jumps to where I movied to.

So since I've hit a dead end with Nomachine I've gone back to my original trials...XDMCP

so I've followed the directions for opening up XDM at


http://www.yolinux.com/TUTORIALS/GDM_XDMCP.html

I'm using Reflection X (since I already have it) but xming has the same results. I can connect, other apps run fine (gimp, mozilla, etc). Performace is very good, no refresh issues like Nomachine NX. However when I run the main app i need it opens still on the local workstation and not my remote X session.

I've even tried crazy things like setting display variables to see if it would trick the application:
When at the local workstation "set" provides DISPLAY=:0.0
On my remote "set" provides DISPLAY=citrix.xxx.com:1.0
so on my remote console I do export DISPLAY=:0.0 which sets it but now when i try to run the stubborn app i then discovered that it is calling for a second application by showing me an error "Could not initialize the UI"
I've even opened up side by side both sessions and set everything in "env" to be exactly the same and it still didn't work.

If i try to run that second app directly I then get
err: ERR_TABLE not in environment

So is there anyone out there who can make any recommendations on how to force this application to run somewhere besides 0.0?

Every method that I have tried of ssh, telnet, nx I am able to open other applications fine remotely. When i try to run this application, as soon as the command is entered the usual terminal window for it opens (remotely) but the application itself pops up on the local workstation (that is if a user is logged in, if no one is logged in nothing happens).

The only thing that will allow access to this application remotely is Nomachine's NX running in Shadow mode because this actually displays the local workstation desktop taking control of it. However I cannot figure out why the refresh issues are present which is why I figured i might as well go back to trying to figure out xdm or such.

The systems being run:
The "server" where there application is installed is Fedora Core 2. I'm trying to connect from a Windows XP system (on the local network) and from a Windows 7 system over the internet through Citrix (Reflection X is installed on the Citrix server). There are 4 of these identical Fedora Core systems and even connecting from one to the other ends in similar results (even through Nomachine NX gives the same refresh problems).

The app I am trying to run is called Xio (cms-rtp.com) when it is run it links to other applications (or modules called rtpdir, pfm, pfm3 and others depending on what function your are doing).

If I ssh -X and do /FOCUS/bin/xio (where the application is) it returns:
Could not initialize the UI.
Application: /FOCUS/bin/rtpdir
Function: InitFocusSystem

So, out of curiosity if I /FOCUS/bin/rtpdir:
cms_err: ERR_TABLE not in environment.


There is no firewall restrictions on the local network at all. And all ports are open.

Thank you.
