X Error of Failed Request : BadAtom

Posted on 2006/02/02 by vnoel

I was using several Unix programs through Mac OS X’s X11, and I was experiencing several crashes (emacs when trying to resize sub-windows, nedit when trying copy/paste, even matlab was spewing error messages) with an error of the type

X Error of Failed Request : BadAtom

After fiddling a while, it appears this is due to a modification of ssh which does not accept trusted X11 cookies anymore. I added

ForwardX11Trusted yes

in the local .ssh/config, and crahes begone ! Joy.

    Yay! Not the sort of thing I would ever have figured out on my own, but SO useful. 🙂

    You rock — this fixed my problem. Why do these error messages have to suck so bad. BTW, how did you root cause this????
