In the project configuration you should have an option:

Start Xvfb before the build, and shut it down after

Here you can specifiy what display should selenium use via the property Xvfb specific displayname . You should set it up to 0. If you don't have that option you should install the xvfb plugin.

Alternatively ssh into the worker and write export DISPLAY=:0.0
