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

I installed Geonode1.1-beta2 on a centrino duo laptop with Ubuntu 10.04,
followed deploying in ubuntu 10.04 instructions.
No virtual machine.
my ram size is 1.5GB.

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.

Cheers

Simone

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.

Thanks everyone for the replies. I think unsetting DISLAY variable might
have
done the trick. works like a charm!

Cheers All.
