Re: Use a second monitor to prevent radiation emissions being read..?
You're being a bit harsh on the folks here -- and entirely unfair to them, as well.
... but little regard for personal privacy.
One person, in fact, already told you the way to avoid electronic surveillance -- but surrounding yourself with a Faraday cage. A quick Google on this will reveal several articles on how to make one cheaply.
This website is for support of Ubuntu-related issues -- which yours clearly is not. So, yeah, you should search for a website that focuses on evading electronic surveillance -- realizing that Googling extensively for such information could very well cause you to become a "person of interest" to those in the "intel ..." community.
Maybe I should try a different website.

Will not respond to PM requests for support -- use the forums.
