Jenkins xvfb plugin issue: No display name received from Xvfb within 10 seconds

[Pooja Shah]

Hi Team,

I'm facing an issue while configuring xvfb plugin, somehow its not finding my display name

Have added it in

1. job->configure->Xvfb specific display name --> 99

2. in Pre steps-> Execute shell--> export DISPLAY=:99

3. in manage jenkins-> manage nodes-> master-> configure-> added env variable name ="DISPLAY" value=":99"

4. added xvfb configuration directory

Is there anything I'm missing in configuration?

Here is the log:

Xvfb starting$ /usr/bin/X11/Xvfb -displayfd 2 -screen 0 1024x768x24 -fbdir /var/lib/jenkins/2014-07-18_11-51-132622983017347894755xvfb

It should some simple thing which I'm missing but didn't find any solution anywhere, Please suggest!

Try to run it  directly on the server, then you should get some more verbose output. One of the common problem which can cause that error is for example missing libXfont package.
Or you can try to turn on option: "Log Xvfb output" in jenkins to get some more info.
