@cycomanic I see something like the opposite. When undocked, there is no DP-2-1. When I dock, both DP-2-1 and eDP-1 show up as connected and enabled, even though DP-2-1 is...

@phillipberndt I don't think a predetect script can help, since the the "workaround" of explicitly enabling DP-2-1 does the very action I wanted autorandr to do automatically, obviating any need...

Ran "socat -u UNIX-RECV:/tmp/sock STDOUT | ts | tee ~/slow.log" in one terminal, and "emacsclient -e '(explain-pause-log-to-socket "/tmp/sock")'; e customize.el ; killall socat", then did a C-x C-c as fast...

xterm is very quick.

```(defun xterm--read-event-for-query () nil)``` works for me, thanks for taking the time to help me debug this, it has been annoying me for months. Weird terminal interactions were definitely not...
