Poor man's dual monitor (using two linux boxes))
 

I got two complete (with video & crt) linux boxes sitting side by side.

I would like to run an app (gimp) on one box and see it display on the other box. (effectively simmulating a dual monitor system)

For example when using gimp I keep my detail drawing screen (zoomed to a detail ) plus palletes and tools on one "workspace" and a "preview" screen on the other, but I have to switch workspaces all the time to see the final effect of my changes.

I tried opening a VNC screen on the second machine, using synergy to let one mouse & keyboard control both boxes.
it really works great!.. as long as you are using 2 different applications.. one on each -display

What I cant get to work is to display some Gimp screens on display:0 and the others on display:1 (to be viewed from the 2nd computer)

If I can get this to work it would be a very cheap and easy way to have multiple displays with out having to buy any extra hardware!!



Any hints out there?

Im not quite sure if this will be any help, but you need to export display variable. It should be something like export DISPLAY=ipofhost:0
as far as i can remember now, very tired...
HTH
-NSKL

i am very sure that's not possible.

What about using xinerama to display across 2 monitors, except thet the second one is "virtual"? (using X or vnc)

alx.

no, because that would require communication between two seperate X servers. Xinerama operate within one server at one time.

I believe you can ssh from one box to the other and use that terminal to to run the program which should open in a window as long as sshd will forward X. Not sure if that does quite what you want though.

Thx but not quite,
What I am interested on is for one app to send various applets to different X terminals..

Something simmilar to how workspaces work on Gnome.

After quite a bit of research and just for closure, I will answer my own question:

I found there is a group building exactly what I want,
you can see it at: http://dmx.sourceforge.net/

alx.

Or another way to do it without new software
 

I'm actually looking for a way to do something that should be simplier, run my KDE XWindows display that normally runs on my Redhat system from my Solaris system. I haven't quite gotten it down yet BUT I did run across somebody describing how to do what you are trying to do.

I found it at
http://quasi.ksl.com/linux/tips.html#export

He says in his notes:
"...how to run apps located on another server, whether it be Solaris or some other UNix variant and then how to port them over to your own XWindows session."

Sounds like what you are after.
To give a brief summary of what he tells you to do:
1. export DISPLAY=machineYouAreInFrontOfIP:0.0 on puter app is to run from
2. xhost + from the console on the machine you are in front of
3. from your telnetted/ssh'd session into the remote machine run the app you're after and you should see it pop up in your current window.

Thought this might be helpful info.
