@natemaia and others:
I am not sure this is anything wrong, but thought it was a little odd so mentioning. I was looking at /etc/X11/xinit/xinitrc. It has lines towards the end that invoke xterm.
Now I looked at my /var/log/pacman.log and to what I can tell, xterm was never in my AL distro.
OK, and I think this may have something to do w/ lightdm acting all weird under some circumstances that I encountered during testing various things (not yaxwm in particular, just a few things here and there).
Again, if this is a red herring, pl. ignore, but thought to mention here in case it is genuinely a bug that comes into play sometimes (I think lightdm reads that file in some logical paths).
