From: Jeremy Phelps <jeremyphelps077 <at> gmail.com> To: 68255 <at> debbugs.gnu.org Subject: bug#68255: 28.2; Can't connect to emacs daemon after logging out and back in. Date: Thu, 4 Jan 2024 14:52:17 -0500
1. Configure your session manager not to kill leftover user processes after logging out. If you're using elogind, this can be done by editing /etc/elogind/logind.conf and setting KillUserProcesses=no. Same process for systemd-logind, except the file is located at /etc/systemd/logind.conf. 2. Log into a new session and run "emacs --daemon". 3. Log out of all sessions for that user. This causes the directory named in $XDG_RUNTIME_DIR to be deleted, and with it, the Emacs daemon's socket. 4. Log back in. 5. Observe that the emacs daemon's process is still there, and that its socket is gone. Working around this problem is difficult because the XDG_RUNTIME_DIR variable whose use causes this problem is referenced in two places: 1. The "server-socket-dir" variable in Elisp. This is fairly easy to change because Emacs can take you right to the definition. 2. The emacsclient binary. Changing the behavior here requires editing emacsclient.c, recompiling, and installing the resulting binary. Except it's too hard to get Emacs to build on modern Linux distros, so I hex-edited the emacsclient binary instead, NUL-ing out all strings containing "XDG_RUNTIME_DIR".
