Hi, I believe the problem is that coq-mode from package coq requires hilit19, see #605024. I would guess that on the desktop you have (proofgeneral) in your .emacs, while on the laptop you have not. Therefore on the desktop *.v files get coq-mode from proofgeneral while on the laptop they get coq-mode from package coq, which requires the nonexistent hilit19. Bye, Hendrik
