emacs in "screen".

emacs in "screen".

[A. Soare]

I started emacs in screen that was running in tty1. DISPLAY was set, and emacs connected to X-server.

I restarted emacs using C-M-Backspace. Emacs continued to run in tty1, but it lost the connection to X-server, and stopped.

Is there a possibility to restart X-server and afterwards to continue the same emacs session? Emacs should reconnect to the X-server in case that is sees that X-connection died.

I'm not sure if you got a reply to this on emacs-help (as I don't read
that list), but I thought I'd share my experience anyway.

Did you try make-frame-on-display?  Did it work?  Do you want emacs to
automatically try making a frame on a display if the display dies?

FWIW, I start emacs --daemon with daemontools when I log in, and then
get my X frame via "emacsclient -c".  Even after restarting X, I can
still get my same session back. The key is to either start emacs with
"emacs --daemon", or to start a "-nw" session in your screen session.
Then do a M-x server-start and connect to that emacs with emacsclient.

Also, you don't really need screen for this.  You can start an "emacs
--daemon" and then connect to that emacs session from the console with
"emacsclient -t".  emacs can do its own session management now, which
will even save you in the rare event that screen crashes.

(All this is contingent on having emacs23, of course.)

Thanks for your answer.
I am sorry for my late answer.

make-frame-on-display is exactly what I want. When I start emacs from ttyx, then make-frame-on-display opens a frame in X, and when that frame closes, the tty session survive and one can run again make-frame-on-display.

Thank you.


Best regards,
