X11 changes between 2.5.1p2 and 2.9p2

[Stephan Hendl]

Hello,

I just upgraded one machine (HP-UX 11.0) from 2.5.1p2 to 2.9p2 and found that a

hendl at host_a# ssh host_b

works fine with authentication agent and X11 forwarding on but a 

hendl at host_b# su
root at host_b# /usr/bin/X11/xclock

afterwards gives errors like

debug: X11 connection uses different authentication protocol.
debug: X11 rejected 0 i1/o16
...
debug: X11 connection to ... broken...

With version 2.5.1p2 these errors don't occur. What shell I do?

Thanks
regards

Stephan
