LyX ⇒ dead keys for accents disappear

[jossojjos]

Hello,

I'm using lyx regularly to type french text using a french keyboard. This keyboard uses dead keys to add some accents (e.g. circonflex, â; trema, ä). However, these dead keys sometimes disappear, and the first stroke on the key gives directly "^" or "¨". I haven't the faintest idea how to get the "dead key" behaviour back; it just starts working at some point. While waiting for a miracle, I have to type all these accents with ERT, which is very annoying.
None of the other programs are affected on my computer; I can type "â" as usual in the terminal, or, as you see, on this forum. In older versions I had the possibility to minimize the window, and then maximize it again, and the dead key behaviour would come back.

I'm using Lyx 2.1.4, which seems to be the latest version available for my OS (CentOS). I have to start lyx by with the option "-graphicssystem raster", but starting it without doesn't solve the problem.

Any suggestions where I should start looking?

My first recommendation would be to try the latest LyX version. I wouldn't be surprised if this behavior has been fixed.

If that's not a possibility, perhaps going to Tools > Preferences > Editing > Keyboard/Mouse > and then check "use keyboard map" and go to browse and choose francais.kmap or french.kmap.

Note that there is a mailing list for French LyX users. lyx-fr. it's very low volume so if you feel like joining it would be great to have you on there.
