In HPUX 11.11, for recent versions
of display and ImageMagick, specifically 5.5.7-34 and 6.4.0
setting the display variable to the hostname:0.0
combo results in an error.

[manitoba] /nfs/manitoba/home/tmr
$ display maskhead.gif
display: unable to open X server `pcx6249:0.0'.

while
setting DISPLAY=130.1.6.249:0.0 (the equivalent IP address for PCX6249)
display works.

Note that for an old version of ImageMagick, specifically 5.2.5,
even recompiled today, a hostname:0.0 works.

A recent version on a Gentoo Linux workstation works normally.

Not sure what the problem could be. ImageMagick simply passes the display string to the X11 XOpenDisplay() method. It only fails if XOpenDisplay() returns an error.

Yup, its a puzzler all right. The funny thing was the old version newly compiled
works - which seems to indicate that its not a versioning problem with X headers.

In all likelihood, there is a (possibly -- occasional) problem with name-resolution on your network. X11 is asking for the IP-address of "PCX6249" and does not get a correct answer...

sigh. That's not it either. I mean I can ping pcx6249 and nslookup works.
Other X programs work as well.
