[comp.windows.x] xperfmon finicky about $DISPLAY

holtz@csmil.umich.edu (10/01/89)

I got the fixes to run xperfmon under SunOS 4.0.3 on my 3/60,
and only one thing is wrong now: I can only get it to open
a remote display if it is given (on the command line or in $DISPLAY)
in the form <internet address>:0 ; <hostname>:0 and <hostname.domainstuff>:0
don't work.
	-  All my old SunOS3-compiled binaries have no such
	   trouble opening displays when run on the same SunOS4 machines
	-  the target display is properly xhost'ed
	-  Oddly enough, xperfmon complains
		can't open dislay '(null)'
	   when $DISPLAY == <hostname>:0, but knows enough to complain
		can't open display '<hostname>:0'
	   when <hostname>:0 is given on the command line.

Has anyone seen this kind of behavior before?
