### LyX dispaying incorrect characters in Math Mode - Linux Mint

Hi everyone,

I actually asked this question originally on the LaTeX stack exchange and it was suggested I ask here instead. Basically I installed Linux Mint 19.1 a few days ago. Before that I was a Windows user. I installed Texlive-full from the ubuntu repository and then LyX. The problem is that LyX displays the incorrect characters in math mode. For example instead of the greek alphabet when I type "\alpha" or "\beta" it prints bold font English letters "a" and "b". Instead of a minus sign it displays "lyxminus". Some characters are still correct such as epsilon but the majority are wrong. the output PDF is correct. I have tried reinstalling both LyX and TexLive. I think it may be the fonts on Mint itself. I tried to update Mint but that made no difference. If anyone has solved this in the past this or knows how to fix it I will appreciate the help.

Hi Jimmy,

welcome to the forum!

Is it a LyX displaying issue, or is the PDF output wrong too?

Can you please post a sample .lyx file, the pdfLaTeX export file (for us LaTeX users without LyX to check the same), and the .log file? The Attachments link is below the text edit field, when writing a post.

Hi Stefan,

Thanks for the response. It's only in LyX, the output file is fine.

Did you install LyX from a (Ubuntu?) repository or from www.lyx.org? Perhaps check the download page for a Debian package that can be installed. (such as by dpkg -i lyx.deb)

It seems to be a LyX issue since it's find in the pdfLaTeX output, or a Mint font rendering issue. If there's a newer version of LyX than you installed, I would give the newer one a try.
