On my Mac OS X 10.5.8, I changed the color background of the Xterm (X11) by adding the following lines to the file .Xdefaults:

xterm*Background:               black
xterm*Foreground:               green
xterm*cursorColor:              LightBlue
xterm*pointerShape:             arrow
xterm*pointerColor:             blue

It was working well. I did not save other modifications to other files. I switched off the Mac.

The day after, the Xterm just does not open. I click on the icon X11. The bar on the top of the screen shows it is going to open but after a few seconds, it turns back to the previous program and does not open X11. Same result if I try to open it from Applications/Utilities/ it just does not open, but NO error messages or other issues to the other programs open.

I tried to check Finder, Go to Folder, /private/etc/paths.d. It shows /usr/X11/bin. This should be correct. So I do not know how to find the error.

I deleted the .Xdefaults and the result does not change. HTere is something unual in the, but I have no idea how to use it . – Fred Apr 1 '12 at 20:30
If X11 is starting up and then dying, /var/log/system.log should contain some indication as to why. – Kyle Jones Apr 1 '12 at 22:10
