Log:
JENKINS-15638 Xvfb 'display name offset' defaults to 0, not 1 as
described, if unset

Fixed in version 1.0.5, thank you for reporting the issue

Still seem to have the same issue. Downloaded latest xvfb.hpi, and restarted Jenkins. PluginManager states version 1.0.5.

Job on first executor still gets the display :0, and a job running at the same time on the second executor gets display :1.
The jobs are building on a node/slave.

Running on Jenkins version 1.486.

Also: The text field itself is always empty, i e if I set a value, and applies the change then reload the page, the text field is empty.

A svn diff on the config.xml shows, when manually setting the value to 1:

<screen>1024x768x24</screen>
<debug>false</debug>
<timeout>0</timeout>
-<displayNameOffset>0</displayNameOffset>
+<displayNameOffset>1</displayNameOffset>
<additionalOptions></additionalOptions>

• added missing getter for display name offset

The display name offset property was missing getter, which was reflected in the empty value in configuration screen. Please upgrade to version 1.0.6, and make sure that display name offset is set to something greater than 0.
