Hello world..

I am trying to enable Xelatex @Lyx but i have some problems . I am ubuntu 11.04 user and Lyx2.0 . I followed this tutorial in order to install Xetex

Then i openned Lyx but i cant enable the option to "use non tex fonts via Xetex/luatex" . I attache a screenshot :

ps1: Lyx's interface is in Greek language
ps2: I have to enable first this option and then use a code in preamble in order to use a font right ?

Thanks in advance , waiting for your support

Start by checking if you properly installed XeTeX (and reconfigure LyX: Tools > Reconfigure, just in case). Type in the Terminal the following:

Code: Select all

xelatex -v

This should return something like this:

Strange. You'd probably have to ask at LyX's mailing list why that option is disabled. But let's see at least can you use XeTeX at all. Do the following:
1. Open LyX, create a new document and type couple of words.
2. In Documents > Settings > Preamble type in:

Code: Select all

\usepackage{fontspec}
\setmainfont{Bitstream Vera Serif}

(you can try any font you like, Bitstram Vera Serif is just an example).
3. Go to: View > View (Other Formats) > PDF (XeTeX) (you can use buttons on the toolbar instead; should be 6th and 7th from the left).
