"ssh -X root, then su -" don't bring terminal

Hi

I'm trying to test the installation of a software in HP-UX (B.11.11). To 
do that, I'm logging in as root[1], then changing to the user[2]. But 
after changing I could not export the terminal[3]. But if I try the same 
using Opensuse 11.0, everything works fine.

In my machine, I issue the command "xhost +", but it doesn't make 
difference.

Does anyone have a hint of what going on?

thanks

Marcelo
