I need to use a lowercase lambda symbol.

The lyx documentation states that if I should be able to use the insert symbol, or copy and paste one into the document, but neither of these methods work.

I've had various error messages, firstly it was

"Error: Encoding file grenc.def not found"

Then in the terminal I ran the commands

sudo tlmgr install textgreek  
sudo tlmgr install greek-fontenc

And now the error message I get is

"LaTeX Error: This NFSS system is not set up correctly"

Is there any simple way to solve this problem? I've tried reinstalling lyx but that has not helped.

  • You can also write $\lambda$ inside ERT.

I've solved the problem. For anyone else looking I ran the commands:

sudo apt-get install texlive-lang-greek
sudo tlmgr install cbfonts

and it worked :)
