I'm happy to provide more = info as needed.=20 That is not what Emacs does. "Reading available displays" is not = possible. Emacs just tries to connect when you do open display. Did you kill the old server and start a new server in the same shell as = you started the first? My guess is that you did not, and so the second = server either gets the correct authentication and thus can connect. To really see what is going on you would need to debug Emacs with gdb = when the make-frame-on-display fails. Jan D.
