so I will ignore the font specification.
[Wizards can fix TFM files using TFtoPL/PLtoTF.]
You might try inserting a different font spec;
e.g., type `I\font<same font id>=<substitute font name>'.
The file was successfully rendered on other machine.
How can I fix it?

How do I install the Greek support file?
I made a full installation of the tex-live on my computer (Linux Ubuntu). How can I verify that Lyx is using this installation (at the university, I installed the Lyx on windows, and worked with no additional considurations).
