Message: Can`t Open Display on HP-UX 10.20

Message: Can`t Open Display on HP-UX 10.20

I have a HP9000 station with HP-UX 10.20, together with X-Terminal HP ENVIZEX.
I have installed Samba+Patch (PHCO_20441). Samba is running now OK, but the
X-Terminal during starting of 3D-2D TriCAD ap. reports: Can`t open display. All
outher aplications starting OK on the X-Term.

Sounds as if the application EITHER cannot establish the xterminals DISPLAY,
try exporting it first : export DISPLAY= :0.0

nb make sure hostname resolution & xterminal configuration is set correctly.

OR either hosts or user based access is playing a part : try running xhost + ?
check the Xerrors (Xservers log file) for details & reference vs. man X and the
X authority section ... any signs of MIT Magic cookies ?
