[BUG] org-link-preview-file emits image not supported in daemon [9.8-pre (release_9.7.10-127-g07dd3b @ /home/bidar/.local/etc/emacs/lib/org/lisp/)]

[BUG] org-link-preview-file emits image not supported in daemon [9.8-pre (release_9.7.10-127-g07dd3b @ /home/bidar/.local/etc/emacs/lib/org/lisp/)]

[Björn Bidar]

Hello,

org-link-preview-file emits "Your Emacs does not support displaying images! "
when restoring buffers with desktop when Emacs was started as daemon.

Steps to reproduce.
1. Start Emacs with --daemon or --fg-daemon
2. Enable desktop
3. Have org-mode buffers containing image previews
4. Restart Emacs
5. Error.

The message false or at least confusing.


Emacs  : GNU Emacs 31.0.50 (build 1, x86_64-suse-linux-gnu, GTK+ Version 3.24.43, cairo version 1.18.2)
Package: Org mode version 9.8-pre (release_9.7.10-127-g07dd3b @ /home/bidar/.local/etc/emacs/lib/org/lisp/)


Regards,

Björn

Thanks for the bug report.

Just checking, do you have

#+startup: imagepreviews

or

#+startup: linkpreviews

in these files?  Or do you call `org-link-preview' or
`org-toggle-inline-images' manually?

I have this in my init.el:
;; Show inline images by default
(setopt org-startup-with-inline-images t)

Ihor, what would be the best way of handling this?  We can add a
`display-graphic-p' test when running the inline-images part of
org-startup, but then link previews that are not images won't be applied
either.

1. As a minimum, we can remove that message and do nothing on
   non-graphical displays. It will be consistent with earlier behavior.

2. Maybe we can move the check about graphics to the specific preview
   functions.
