Subject: 24.5; crashes when X dies
Date: Thu, 24 Nov 2016 11:41:19 +0100

I run Emacs in text mode (-nw) under screen.  I use screen in an X
virtual terminal.  From there, I create a frame under X using
make-frame-on-display.  So I have a text frame and a graphic frame.

If X dies, Emacs dies.  I wish it did not die, but only deleted the
graphic frame.

The error message (below) says that Emacs cannot recover from X
disconnects.  However in this case it has a text frame, it looks strange
to me that it can't even keep running on the text frame.  If htis is the
case, is there any workaround?

THanks for caring


When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://bugzilla.gnome.org/show_bug.cgi?id=85715
