[clue] 'Export display' question

[foo7775 at comcast.net]

Thanks for the tips David. My previous experience (which wasn't a whole lot) with running X on a remote system was Linux-to-Linux, & if memory serves, I didn't have to work *too* hard to get it to work. I suspect that the issue lies in not having enough of the needed packages/libs installed on the server - but since I now have the printers working without having to run the ./setup binary, it's now more of a theoretical question. 

Asking RH to support the printer is definitely a good idea, & I'm not shy about opening tickets with them - but I've also been in situations (happily, not with RH) where each of the 2 vendors involved are pointing fingers at the other... 

Thanks again, 

T.

A couple of thoughts. 

First, your display is almost certainly not :0.0. And if the forwarding is working SSH will set 
$DISPLAY for you. 

On the server you'll need enough X client stuff for the program to run. If it's statically linked 
that might be very little, or you might need a lot of the X libs (of appropriate versions). 

On your workstation you need enough X server stuff for the client to display. I guess maybe Xming 
does that. I think I used Cygwin a long time ago but it did a full desktop, not seamless windows. 

You should probably ask RH to support your printer. You paid them for it and if you have to figure 
everything out by yourself you'd be running CentOS.
