MacBook Pro (13-inch, Mid 2010), saddled with High Sierra 10.13.6 (as far
as it will go).
Back when I was running Sierra these tools worked just fine; after
upgrading to HS (and rebuilding MacPorts that took almost a day) things
went pear-shaped:
mackie:~ dave$ xv
xv: Can't open display
mackie:~ dave$ gimp
Cannot open display:
mackie:~ dave$ echo $DISPLAY
mackie:~ dave$
Is this something I forgot to do during the upgrade? I set $DISPLAY to
":0" (an old Unix trick) to no effect, so I guess it's using a named pipe
instead but I cannot find it; poking around doesn't seem to uncover
anything applicable to this, and I certainly won't trust any "advice" on
StackOverflow.
Where has my 70yo brain screwed up?
Thanks.
