Hi Andres, Unfortunately the underlying libraries doesn't work based on DISPLAY. You can use either of the approach [1] or [2]. Thanks Nagappan [1] - <a href="http://ldtp.freedesktop.org/wiki/Executing_scripts_remotely">http://ldtp.freedesktop.org/wiki/Executing_scripts_remotely</a> [2] - <a href="http://bazaar.launchpad.net/~nagappan/hudson-x11-guitest/head/files">http://bazaar.launchpad.net/~nagappan/hudson-x11-guitest/head/files</a> <div class="gmail_quote">On Wed, Oct 24, 2012 at 7:59 AM, Andres Riancho <<a href="mailto:andres.riancho@gmail.com" target="_blank">andres.riancho@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">List, Sorry if this is a FAQ but I was unable to make it work. I want to run LDTP in Xvfb and I don't seem to find how to do it. I've read some documents [0][1] and tested extensively but found myself in a dead-end. This is what I'm doing: Console #1, start Xvfb: /usr/bin/Xvfb :2 -screen 0 1024x768x24 -fbdir /tmp Console #2, start helloworld.py application in :2: DISPLAY=:2 python helloworld.py Console #3, start VNC server on :2 to verify that helloworld.py is running: x11vnc -display :2 -shared -forever Connect to the VNC server and find that the window is there. Without window decoration, but it is there. Console #4, run sniff.py [2] on display :2: DISPLAY=:2 python sniff.py hello Expected result from the last command would be something that contains "frmhelloworld.py"; instead I see the list of windows that are in my working X (:0). In other words, getwindowlist [3] seems to be ignoring the DISPLAY environment variable. I've also tested this: export DISPLAY=localhost:2 python sniff.py hello And I still get the same result. If, after the export I run "gedit", the text editor will appear on my Xvfb (which I'm watching using VNC). So, the question would be... how do I tell LDTP to "connect" / "run" in a different display? Is there any updated documentation on LDTP+Xvfb?
