Sometimes the API can change. I saw this code in the thread today:
(theme (grub-theme (resolution '(1920 . 1080)) (image (local-file "/home/shiroikuma/0/pictures/grub/gnu-grub.png"))) Notice that it uses "image" and not "images". I don't know if that is the fix...I am just pointing that out. -- Joshua Branson Sent from Emacs and Gnus
