[Info-xnee] Xnee and Xvfb

[Josh Wyatt]

Greetings,

Firstly, let me thank you for the excellent tool that Xnee is.  I'm quite 
impressed by the flexibility.

I am writing to ask for some help using Xnee with Xvfb.  I have been using Xnee successfully to record and playback sessions on Xnest sessions.  

However, when I attempt to replay the same events on an Xvfb display, Xvfb 
seems to ignore motion/mouse/keyboard events.  Using xwd and xwud, I can see 
that the display presents the windows and whatnot as I start them remotely; but 
they do not appear to receive keyboard and mouse events.

Any thoughts?  Here is a simple test to reproduce the problem.

My setup:

Centos 4.4, using xorg-X11 Xnest and Xvfb 6.8.2.

cnee --version reports:

address@hidden ~]$ cnee --version
Xnee 2.05

How to reproduce:

I started an Xnest session under my existing GUI for recording:

Xnest :1 -ac -geometry 1024x768 &

Start an xterm in that display:
xterm -display :1 &

Start the recording:
cnee --display :1 --record -o test.xnl --mouse --keyboard --time 5

Mouse to the xterm in the Xnest window, click on it to gain focus (probably not 
necessary since no WM is running), and type some stuff (pwd, ls -l, etc)

Ctrl+C in the cnee record shell.


Okay... Time for replay into the Xvfb...

I can setup the Xvfb session exactly the same with:

Xvfb :3 -ac -screen 0 1024x768x16 &

xterm -display :3 &

At this point I used xwd to determine that the xterm had indeed started, and 
was located in the same position:

xwd -root -out t.xwd -display :3
xwud -in t.xwd

... and it looks fine, ready for action;

I then replay the file:
cnee -v --display :3 --replay --file test.xnl

(cnee provides some output showing it executes the events...)

And use xwd/xwud to snapshot and review Xvfb's display:
xwd -root -out t.xwd -display :3
xwud -in t.xwd

...And nothing has happened in the xterm.

Any thoughts would be GREATLY appreciated!  I have attached my example xnl file 
'test.xnl' from above.


Thank you in advance, and cheers,
Josh
