Problem with "not equal" Math Symbol

Postby Xander314 » Mon Sep 05, 2011 12:37 pm

Hi. I'm using TexMaker on Ubuntu 11.04, with whichever tex distribution the package manager installed by default.

My problem is this:
even if $\lambda(i) \neq 0$ for $i > j$.

The problem is that \neq always appears as an equals sign = in the produced file. Any ideas why this might be and how I can fix it?

I've seen this problem and made some suggestions here: LaTeX vs pdflatex on \neq.

Posting just one single line of code is useless. Build a minimal example that is compilable out of the box and reproduces the undesired behaviour clearly. The below example works fine for me.

  $\lambda(i) \neq 0$ for $i>j$
