Alexander:
Echo $DISPLAY returns localhost:0.0 from my shell running from
Terminal.app. From the xterm I run from Apple's X11 (via the
Applications pull-down menu) it returns :0.0. From what I understand
that is effectively the same thing.
DISPLAY is set to localhost.0.0 from my .cshrc file.

I too, of late, have been having trouble running X apps from
Terminal.app. All used to be well until I temporarily switched from
Apple's quartz-wm in rootless mode to Window Maker in full screen
mode. Upon returning to quartz-wm, I get the following error:
[santorini:~] marc% xclock &
[1] 2556
[santorini:~] marc% Error: Can't open display: localhost:0.0
[1] Exit 1 xclock
Now my DISPLAY environment is properly set:
[santorini:~] marc% echo $DISPLAY
localhost:0.0
I do get an error in Console but I do not know if it is related to my
problem:
XFree86 Version 4.4.0 / X Window System
(protocol Version 11, revision 0, vendor release 6600)
[DRI] screen 0 installation complete
Screen 0 added: 1024x768 @ (0,0)
Could not init font path element /usr/X11R6/lib/X11/fonts/CID/,
removing from list!
Completely unrelated.
X apps launch and run just fine from within an xterm.
I use Apple's X11.app.
Any suggestions?
Thanks,
Marc
I would suspect that you've got a stale reference to display :0
somewhere (e.g. a zombie xinit process or a lockfile) and that
X11.app is putting you on display :1 . You can confirm this by
checking DISPLAY from an xterm.
(the "screen 0" message on starting X11 still applies because you're
on screen 0 of display 1)
X11.app is clever and will increment DISPLAY if another X server is
running. I don't know exactly why it was set up that way, though I've
exploited it myself--XDarwin.app on :0 and X11.app on :1, for example.
