Another thing you could try is to unset the DISPLAY environment variable in whatever shell you are using when you start GeoNode and Geoserver. For csh and tcsh the command would be

unsetenv DISPLAY

for bash and sh I think it's

unset DISPLAY

but I'm not so sure.

Ok,
seems that java don't recognize your display.

You can try to create a virtual framebuffer and see what happens.
This worked for me as a temporary workaround.
Try:

- Xvfb :1 -screen 1 1024x768x16 &
- export DISPLAY=:1

and restart tomcat.

    10.04, followed deploying in ubuntu 10.04 instructions.
    No virtual machine.

        Hi Allan,

        can we have more details about your machine? Are you running
        Geonode on a virtual machine?

        I'm not sure to be able to help you but some time ago I ran in
        a similar problem with Debian6 on a pretty old version of VmWare.

        Thanks

        Simone
