Honestly, I don't see any reason why the hostname would have anything
to do with your crashes... I'd assume that you simply got lucky and
the hostname is pure coincidence... sorry I can't be more help.

Hi Jeremy,
Thanks for getting back to me on this.
I found out that the display variable was being set to 0:0 in
my .profile file. This solves at least part of my problem.
I also, by accident, discovered a way to make the OpenGL problem
disappear, which might point to the root of the problem.
Normally, my MacBook Pro is connected to either the internal network
in my lab, or to my own wireless network at home. In both cases, the
machine sets its own hostname. However, today, while trying to
replicate the crash, I was using Cornell's campus wide wireless
network, and my computer was given the hostname rrdhcp62-381, and
was unable to replicate the crash.
I changed back to our internal network, and the problem manifested
itself within a few rotations in pymol. The problem still existed
after changed back to wireless networking, but vanished after I
restarted in wireless mode (with the ethernet ports on my computer
switched off).
The pymol crash problem doesn't seem to exist when the hostname is
set by a remote dhcp server, but seems to manifest itself when the
computer is allowed to set its own hostname.
This is very strange to me.
Do you think that it could really be the cause?
Thanks! and all the best,

Hi Buz,
From what you describe below, it looks like you have the DISPLAY
environment variable set somewhere. You should not be setting this
environment variable. Please check http://trac.macosforge.org/projects/xquartz/wiki/X11-UsersFAQ#sshXforwardingdebugging
for information on locating where this is being set, and remove it.

Hi Jeremy,
Thanks for getting back to me on my post!
I'm sorry that I haven't got back to you in a while. I've been
really
busy with experiments and paper writing.
Also, I'm confused. How do I get the console log for X11?
As for the Terminal.app, if I do startx I get the following;
xauth: creating new authority file /Users/buz/.serverauth.561
xinit: Detected Xquartz startup, setting file=X,
argv[0]=/Applications/Utilities/X11.app/Contents/MacOS/X11
XQuartz starting:
X.org Release 7.2
X.Org X Server 1.3.0-apple9
Build Date: 20080117
TransformProcessType: Success
meta mod is 4
When I try to launch an xterm from the X11 program that has now
started, I get this error message (This is after a crash of X11):
xterm Xt error: Can't open display: :0.0
xterm Xt error: Can't open display: :0.0
xterm Xt error: Can't open display: :0.0
If I run the unset DISPLAY; startx command, I can get an xterm to
appear in X11.
Thanks! and all the best,

I have not had this problem of X crashing and refusing to
start. Can you please provide the console log that shows the
crash and your attempts to start X?
What happens if you just run 'startx' from Terminal.app?
Provide the console output from that as well.
What happens if you run 'unset DISPLAY; startx;' from
Terminal.app? Provide console output from that as well.

Dear All,
I've been suffering crashes when I use the OpenGL/GTK
application Pymol on X11 ever since I upgraded to X11 2.0. This
wasn't so bad, as I could just restart X11. However, I recently
upgraded to X11 2.1.1 and have found that the crashes continue,
but in order to successfully restart X11 I need to restart my
Mac. If I don't restart, I can restart the X11 application, but
can't display and X11 windows.
Could some one suggest a fix?
Thanks! and all the best,
