I read with enthisiasm the answer to the query "Enchanting Lyx" in LXF 161 Answers section. I run Lyx on a bunch of different computers, three of them running version 2.0.0, and one of them seems unable to activate a spellchecker, while the other two do fine. The rogue computer, and one of the good ones, runs Ubuntu 12.04 (the "bad" is using a KDE desktop, while the "good" uses LXDE).
I created the (missing) ~/.enchant directory, and the enchant.ordering file. Enchant is installed, of course, as well as aspell, ispell, and hunspell. That didn't work, so I dwelved in the configuration files for Lyx, hand editing the "preferences" file so it would match the spellechecker instruction in the "good" system, but that didn't work either. I did try to "Reconfigure" every time I chnaged somehting, but nothing changed.
By the way, any attempt to activate the spellchecker from within Lyx fails, since the "spellchecker engine" entry in the Tools > Preferences > Language Settings > Spellchecker is grayed out, and no cicking brings it up.
ANy suggestion would be greatly appreciated - I can move my files to a "good" sytem for spellchecking purposes, but it is a pain...
