I want to restart Emacs at the same cursor position in the file (or buffer) I was just working on.

In my Emacs config I have the following code to try and do this:

(use-package desktop
      :straight nil
      ;;:defer 1
      :init
      ;; Automatically save and restore sessions
      ;; FIX: Replace hardcoded desktop-dirname with my-savefile-dir
      (setq desktop-dirname             "~/.emacs.d/desktop/"
        desktop-base-file-name      "emacs.desktop"
        desktop-base-lock-name      "lock"
        desktop-path                (list desktop-dirname)
        desktop-save                t
        desktop-files-not-to-save   "^$" ;reload tramp paths
        desktop-load-locked-desktop nil
        desktop-auto-save-timeout   30
        desktop-restore-reuses-frames nil
        desktop-buffers-not-to-save
        (concat "\\("
            "^nn\\.a[0-9]+\\|\\.log\\|(ftp)\\|^tags\\|^TAGS"
            "\\|\\.emacs.*\\|\\.diary\\|\\.newsrc-dribble\\|\\.bbdb"
            "\\)$"))
      (setq desktop-restore-eager 1)
      (desktop-save-mode 1)
      (desktop-read)
      :config
      (add-to-list 'desktop-modes-not-to-save 'dired-mode)
      ;;(add-to-list 'desktop-modes-not-to-save 'Info-mode)
      ;;(add-to-list 'desktop-modes-not-to-save 'info-lookup-mode)
      (add-to-list 'desktop-modes-not-to-save 'fundamental-mode))

Note: This is code updated slightly from the original post, but the issue still remains.

It seems to save the cursor in the given file if I exit.

However the problem is that when Emacs opens, it opens many buffers in separate windows. Each Emacs window appears to be a clone of the others . This is confusing and not the intended outcome. Not sure what is causing this issue.

For example, if I was working on file1.org and left it at column 10, line 20, then I want a single Emacs window to open in file1.org at column 10, line 20. I don't want multiple windows to open with any previously visited Dired buffers etc.

I can confirm that if I comment out the above code, the problem goes away, but so does the required effect, i.e., I no longer start at file1.org at the given location.

Here is a screenshot of the multiple windows that open when I startup Emacs.App (v28.1) on my macOS (Monterey v12.1):

I can clarify my settings further if needed.

  • I'm not quite got your question, but maybe you can try (setq desktop-restore-eager 1) to restore only the frontmost buffer immediately.

  • @TianshuWang - thanks for your feedback. This didn't work. The main issue is that with the current setting above, multiple emacs windows open when I re-launch emacs. If I was last working in file1.org column 10, line 20, this is exactly where I would like emacs to have my cursor on startup. Right now it is opening up dired buffers etc, even though I tried to ignore them. Does that clarify better?

  • @TianshuWang I've added a screenshot to make it easier to see the issue. Three emacs windows open, when I would just like one window to open.

  • I cannot reproduce with emacs -Q with your config like this. Would you mind delete your desktop file and check with emacs -Q?

  • @TianshuWang - Thanks for your efforts and suggestion. I tried to delete the emacs.d/desktop/emacs.desktop and emacs.d/desktop/lock files and restart. It did work as intended once. But since then I can't reproduce this even if I keep deleting these files and restarting. I've updated my config slightly in the original post. Is there some issue with the lock file setting?
