Hej list. After a debian update of several packages (i don't even know which ones, but not lyx), all the maths symbols in lyx are written as ERT ! Someone had a similar pb last week, but i don't know what was the conclusion. Some time ago i had exactely this pb, that i solved by installing the latex-ttf-font package. I tried it, but this time it has no effect ! Thanks for help ...
