does simple "DISPLAY=" and "xhost +" not work anymore?

Did you check the firewall settings? If I remember correctly, the
default settings will block this. I think most people tunnel X
connections over SSH now days - both for security and because the
compression speeds things up.

As a side benefit, if you use "ssh -Y" to make connection to the
remote machine, you don't have to play with xhost of DISPLAY - ssh
takes care of this for you.
