I want to use XeLaTeX to compile a file like
\documentclass{article}
\usepackage{fontspec}
\begin{document}
$a_1+a_2+\cdots+a_n\geq n\sqrt[n]{a_1a_2\dots a_n}$
\end{document}
but there is some error:
/texmf-dist/tex/xelatex/euenc/eu1lmr.fd)kpathsea: Invalid fontname `[lmroman10-regular]', contains '['
! Font EU1/lmr/m/n/10=[lmroman10-regular]:mapping=tex-text at 10.0pt not loadable: Metric (TFM) file or installed font not found.
relax
l.100 \fontencoding\encodingdefault\selectfont
?
After searching I knew I had to install package lm to display latin modern font. so I download the package and copy the files to right dictionary, then I run texhash. but the symbol like \geq and \cdots dispeared. The log file said:
LaTeX Font Warning: Encoding

What shall I do?

I upload the two pdfs (including lmodern package or not) at http://ifile.it/q0pdnra/test.zip.
